Kitchen:

interaction syles

monitor is too obtrusive, not ambient
mapping of plates vs. info (same vertical line)
less visual info -> only calories (need to be confirmed with nutritionist)

discussion
read: submitted paper

Readings:

D. Norman, "The Next UI Breakthrough, Part 2: Physicality", ACM Interations, vol. 14, issue 4, 2007

embodiment -> physicality
e.g. Wii

K. P. Fishkin et al, "Embodied User Interfaces for Really Direct Manipulation", Communications of the ACM, vol. 43, No. 9, 2000

embodied UI: allow users manipulate devices in a variety of ways

D. Chisnell et al, "Where Technology Meets Green Bananas", ACM Interations, vol. 14, issue 3, 2007

"don't want to wait for green bananas to ripen" -> analogy for learning technology: people don't want to have time for unfamiliar devices
design for again

D. Norman, "Simplicity is Highly Overrated", ACM Interations, vol. 14, issue 3, 2007

he argues that people (customers) actually want to have more functions/features instead of simple design.

Reality-based interaction?
http://www.cs.tufts.edu/~jacob/theory/

D. Norman, “The Next UI Breakthrough: Command Lines”, Interactions Magazine, vol. 14, Issue 3, 2007

History: command line à GUI à command line again, since GUI works well only when the number of alternative items or actions is small
Command line: mail, desktop, search engine, OS, etc. à answer engine
More efficiently, flexible, robust with synonyms (think about WordNet), labels, tags, esp. when files are difficult to manage with visual structure
(recall the project of searching/executing applications by commands, shown in CHI07 and before)

F. Sampson, “Why Do I Want Ambient Intelligence?”, Interactions Magazine, vol. 12, Issue 2, 2005

Debate of intelligent in the environment with people

W. Newman et al, “Guide to Successful Submission: Papers”, http://www.chi2005.org/cfp/guide.html, 2005

Main: show contribution à let’s think about how to address our contribution of kitchen
Focus on “tracking/providing nutritional information that traditional cooking process and methods can not provide”?
2 parts: technology (evaluate: accuracy); interface / information visualization (evaluate: how well people can get the info)
Persuasion / behavior change: leave it to next stage?

CUTTING SCALE 2006

"Here is a concept for a cutting board that has an integrated scale
within a defined area on it's surface. Ingredients can be cut and
measured on the same surface with very little extra effort.

There has been a tranformative trend in cooking based around the
science of food. Central to this is the idea that precise measurement
leads to more possibilities for new flavors. Recipes will become more
demanding, requiring simple ways to be precise in the kitchen.

Cutting scale, measures 10" x 15" and has won a 3rd place in
designboom's "your way to coway" competition. Exhibition in Seoul
Korea to be announced."

We are investigating several applications of such a technology, including communication with mobile phones to collect behaviour data, face recognition to identify members of a family as well as clothing store application."

[CSCW] Collocated Collaborative Work

2006-07-16T22:30:00.000+08:00

Concepts that Support Collocated Collaborative Work
Inspired by the Specific Context of Industrial Designers
H.Wang, E.Blevis
Human-Computer Interaction Design Group, School of Informatics, Indiana University, USA
CSCW 2004

true:

designers:

tend to use large amounts of visual data
need large workspaces to present information in the way that does not clutter the workspace, but is still easy to view and manipulate all at once

especially when engaged in activities that involve sketching and annotation, it is imperative that interaction technologies do not impede the dynamic nature of the
interactions

Insights from observations:

Seating orientation
Reach
Simultaneity
Use of physical objects
Large work-surfaces, one concept to a sheet, retrieval and comparison
Privacy level
Orientation of Documents

Then they design concepts from observations
My Thoughts:

A good paper to understand ways and details of collaboration
To design a good UI for collaboration, there are lots of things for us to think about and consider - we should match or apply these insights to the system

2006-07-12T10:48:00.000+08:00

ARIS: An Interface for Application Relocation in an Interactive Space
Jacob T. Biehl and Brian P. Bailey
Dept. of Computer Science, Univ. of Illinois Urbana, IL, USA
Graphics Interface 2004

ARIS:

an interactive space window manager
to enable a user to better manage information in an interactive space
provides an iconic map of the space that enables a user to visually relocate applications among screens
contribution: provide direct manipulation interface

build on top of Gaia, a middleware OS that manages resources in their Active Space Lab

iteration I: multiple Low-fidelity prototypes

users dislike:

select and drop
use of a back and forth gesture
textual list

users like:

select a button from the title bar
iconic map interface
want strong orientation cues

iteration II: revised low-fidelity prototype
lessons learned:

enable a user to initiate a window relocation task from a window's title bar
a 2D iconic map of the space may be good enough for window relocation tasks
provide feedback:

in the space as a user interacts with the iconic map
that transcends the end of the relocation task

users believe that the use of an interactive space could enhance collaborative work
...

My Thoughts:

although our scenario is different from theirs, and also we want it to be automatic map, however, is the difference big enough? Or we just combine different works together?
speaking to UI, our original rough idea is almost the same... just that users don't need to orient themselves
doing rough prototypes => tradeoff: time and results/expectations
we should really think of a novel and different interface to achieve our goal, or works are too similar, but, this is not easy

the creation of a guiedlines document engages the design community in a lively discussion of input or output formats, action sequences, terminology, and hardware devices.
examples: navigating the interface, organizing the display, getting the user's attention, facilitating data entry

2.3 (middle-level) Principles

while guidelines are narrowly focuesd, principles tend to be more fundamental, widely applicable, enduring, and need more clarification.
no single design can satisfy all users and situations => must characterize
determine users' skill levels

"know thy user" - difficult, often undervalued
all design should begin with an understanding of the intended users, including population profiles
the process of getting to know the users is never ending: much to know, keep changing
novice of first-time users; knowledgeable intermittent users; expert frequent users

identify the tasks

the set of tasks must be determined before design can proceed => task analysis (involve long hours of observing and interviewing users)
use a matrix of users and task - include frequenicies

choose an interaction style (blending may be approprate when required tasks and users are diverse)

direct manipulation

users' tasks can be greatly simplified by visual representation of the world of action
appealing to novice

menu selection

read a list of items => select the one most appropriate to their task => observe the effect
have clear stucture to decision making
for novice, intermittent users, applealing to frequent users

form fillin (fill in the blanks)

data entry is required
see a display of related fields => move a cursor among the fields => enter data where desired
some trainning may be necessary
appropriate for knowledgeable intermittent users or frequent users

command language

provide strong feeling of being in control
error rates are high, training is necessary, retention may be poor

natural language

limited sucess thus far
provide little context for issuing the next command
slower, more cumbersome
knowledgeable users

8 golden rules of interface design

strive for consistency
cater to universal usability
offer informative feedback
design dialogs to yield closure
prevent errors
permit easy reversal of actions
support internal locus of control
reduce short-term memory load

2.4 (high-level) Theories

levels of analysis throries

(top-down nature, convenient, effective in early days with command-line input, but relevant today)
conceptual level - users' mental level of interactive system
semantic level - decribes the meanings conveyed by user's input and by computer's output display
syntactic level - defines how user actions that convey semantics are assembled into complete sentences that instruct the computer to perform certain tasks
lexical level - deals with device dependencies and with the precise mechanisms by which users specify the syntax

stages-of-action models

7 stages of action that users go through in trying to use interactive products (arranged in a cyclic pattern):

forming the goal
forming the intention
specifying the action
executing the action
perceiving the system state
interpreting the system state
evaluating the outcome

4 principles of good design:

the state and the action alternatives should be visible
there should be a good conceptual model with a consistent system image
the interface should include good mappings that reveal the relationships between stages
users should receive continuous feedback

critical points where user failures can occur: users...

can form an inadequate goal
might not find the correct interface object 'cuz of an incomprehensible label or icon
may not know how to specify or execute a desired action
may receive inappropriate or misleading feedback

GOMS and the keystroke-level model

GOMS: goals, operators, methods, and selections rules

users: begin by formulating goals & subgoals
=> think in terms of operators
=> achieve goals by using methods
work nicely for describing steps in decision making while carrying out interaction tasks

keystoke-level

simplified version of GOMS model

Consistency through grammers

a command language or set of actions should be orderly, predictable, describable by a few rules => easy to learn and retain
action grammar
task-action grammar (TAGs)

widget-level theories

some situation: hard to accept low level of detail
alternative approach: follow the simplifications made in the higher-level UI building tools
create a model based on widgets supported in the tools

context-of-use theories

profound scientific method of experimental and cognitive psychology
cognitive model of orderly human plans
physical space became an important notion for those who began to think more about ubiquitous, pervasive, and embedded devices
other models: emphasize the social environment, motivations of users, or the role of experience
especially relevant to mobile devices and ubiquitous computing innovations

2.5 (high-level) Object-Action Interface (OAI) Model

emphasize on the visual display of user-task objects and actions
understanding the task => create the metaphoric representations => make the interface actions visible to users

[UI] How about our project?

2006-07-01T22:07:00.000+08:00

we should understand what users really need first.
i'm not sure whether our design really provideｓ a good solution or not.
our concept is great, and does hit the problem (according to the book about collaboration), but the UI part has a big question mark.
it will be better to survey / do user study before we just implement.
visibility: according to our current design, will users really look at it? or will they be bothered?
we can neither ask them to stop working and just watch our system, nor ask them set up every working software as transparent background - that doesn't make sense, not good UI.
we should provide an UI for users to focus on their work well (see section 1.4)
are there any professors we can consult with about UI in NTU?
(to be continued...)

[UI] Ch10 Collaboration

2006-07-01T17:34:00.000+08:00

(Designing the User Interface, Ben Shneiderman and Catherine Plaisant, Addison-Wesley, 2004, ISBN 0-321-19786-0)

10.1 Introduction

CSCW (computer-supported cooperative work): new acronym

still debate whether it includes copperative, collaborative, and competitive work
focus on:

designing and evaluating new tech to suport work process
study social exchanges, learning, games, entertainment

groupware

current trends lead to the suggestion that most computer-based tasks will become collaborative, just as most work environments have social aspects
collaboration: motivating force for using computer -> direct collaboration (direct manipulation of display elements is part of larger goal)

10.2 Goals of Collaboration

people collaborate 'cuz doing is so satisfying or productive
collaboration can have purely emotionally rewarding or specific task-related goals
analyzing:

focused partnerships are collaborations between 2-3 people who need each other to complete a task
lecture or demo formats have 1 person sharing info with many users
conferences: many-to-many msg
meeting and decision support can be done in a face-to-face meeting, with each user working at a computer and making simulaneous contributions.
shared window + private window + large-screen projectors -> enable simultanrous shared comments that may be anonymous
...

the potential market for innovative software tools is large, but challenging 'cuz of numerous and subtle questions
reserach in collaborative interfaces is often more complicated than in single-user interface
researchers must invent their own methodologies
collaboration also facilitates awareness of a partner's gaze and body languange and enhances trust-building eye contact

10.5 Face-to-face Interfaces: Same Place, Same Time

work together in the same room: use complex shared technology

10.5.1 electornic meeting room. control rooms, public spaces

computer presentation:

reduce eye contact
turn a lively dialog into a boring monologue in a dark room

challenges

understand the role of technology in support info transfer
recognize the appropriate role of shared contol

benefits:

group memory enables users to pause, reflect on info, and serve as a oermanent record of what occrred

several existing shared workspace:

Capture Lab, LiveBoard, Mimio, SMART Board, etc.

interaction in public spaces with wall displays may be through personal computers, mobile devises, or special input devices.

pros: everyone sees the same display, can work communally to produce a joint and recorded result
cons: coordination may be complex, technology distraction, nice ideas are hard to deliver

the casual nature of display:

facilitates info sharing
promotes awareness of what others are doing

questions for consideration (p446 box10.1)

6.4 3D Interfaces

"enhanced" interface may be better than 3D reality: enable superhuman capabilities
make the interface better than reality
questionable application: those which simple 2D representations would do the job
successful application: game environment, 'cuz increasingly rich social contexts based on spatial cognition
provide 3D desktops and workspaces, sometimes based on office and room metaphors, but not yet spawned successful products.
modest use of 3D techniques: add highlights to 2D interfaces, e.g. button
-> improve use of spatial memory
-> but also distracting (visual complexity)
check list for effective 3D interface:

...
keep text readable
simplify user&object movement
enable users to construct visual groups to support spatial recall

guidelines for inclusion of enhanced 3D features:

provide overview so users can see the big picture
provide history keeping
enable remote collaboration
...

Enhanced 3D interfaces could be the key to making some kinds of 3D teleconferencing, collaboration, and teleoperation popular.

[UI] Ch1 Usability of Interactive Systems

2006-07-01T17:30:00.000+08:00

(Designing the User Interface, Ben Shneiderman and Catherine Plaisant, Addison-Wesley, 2004, ISBN 0-321-19786-0)

1.1 Introduction

HCI (human-computer interaction) began by combining the data-gathering methods and intellectual framework of experimental psychology with the powerful and widely used tools deveoped from computer science.
UI changes many people's life
the motor, perceptual, and cognitive foundations are growing firmer, while the social, economic, and ethical impacts are becoming clearer.
some designers promote:

persuasive technologies that change users' behavior
multi-model or gestural interfaces that facilitate use
affective interfaces that respond to the user's emotional state

1.2 Usability Requirements

making a checklist of subjective guidelines: have thorough understanding of the diverse commmunity of users and the tasks that must be accomplished
when an interactive system is well designed, the interface almost disappears, enabling users to concentrate on their work, exploration, or pleasure.
goals:

ascertain the users' needs

what tasks and subtasks must be carried out
frequent / occasional / exceptional / repair tasks

ensure proper reliability

user's trust of systems is fragile

promote appropriate:

standardization - common UI features across multiple app
integration - file formats
consistency - common action sequence...
portability - potential to convert data and share UI across multiple SW and HW environments

complete projects on schedule and within budget

1.3 Usability Measures

practical evaluation

time to learn
speed of performance
rate of errors by users
retention over time
subjective satisfaction

after multiple design alternatives have been raised, the leading possibilities should be reviewed by designers and users.
high-fidelity online prototypes create a more realistice environment for expert reviews and usability testing

1.4 Usability Motivations

the enormous interest in interface usability arises from:

the growing recognition of how poorly designed many current interfaces are
the benefits elegant interfaces bring to users

exploratory, creative, and collaborative interfaces:

users may be knowledgeable in the task domain, but novinces in the underlying computer concepts
their motivation is high, but so are their expectations

at best, having computer vanish as users become completely when the computer absorbed in their task domains.

provide direct manipulation representation of the world of action
then tasks are carried out by rapid familiar selections or gestures, with immediate feedback and new sets of choices
users can keep their focus on the task, with minimal distraction in operating the interface

VIOs were designed to express intimacy in a rich manner over a low bandwidth connection
evaluated using a logbook which included openended questions designed to understand the context within which the VIO was used.
a single bit of communication has no value
the utility of a single bit of communication cannot be judged by how many packets of information are transmitted and received, but rather are dependent on external factors
Must also evaluate our technology with metrics that go beyond task completion

ComSlipper: An Expressive Design to Support Awareness and Availability
Carnegie Mellon University
CHI2006

difficult to:

maintain a sense of connection with others, to communicate with others in an emotionally rich way
know whether one is available for initiating a conversation in an appropriate context

designing for two people in an intimate relationship
Chose a slipper because it metaphorically represents comfort, warmth, and ease of use.& its wearable and mobile properties
Prototype:

LED: different emotions

covered with aesthetic fabric

communicate through USB port (future: bluetooth)

5 interactions:

presence => warm

anxiety => light, jumping signal

happy => light, brisk flashings

sad => light, slowly drop down signal

missing (I'm thinking of you) => vibration

Future work:

furthur user evaluation

wireless implementation

extending the network from one to one to one-to-many

explore more flexible, personalized interactions

(C4 Smart cup) H. Gellersen, M. Beigl, H. Krull, The Mediacup: Awareness Technology Embedded in an Everyday Object, HUC 1999.

It's a cup augmented with sensing, processing and communication capabilities, and broadcast in smart environments with context.
I think the idea is quite interesting, and they also consider the basic properties - the cup can also be dishwashed, so it is now a cup with more functions and added values that can be helpful to our life and still remain original usage.
Since this paper is published 7 years ago, I think the information is not enough. Check their website (http://mediacup.teco.edu/) - their associated projects are also (even more) interesting.

(C5 Smart mirror) Nicolas Roussel, Helen Evans, Heiko Hansen, Mirrorspace: using proximity as an interface to video-mediated communication, Ubicomp 2003.

It's a video communication system that uses proximity as an interface to provide smooth transitions between peripheral awareness and very close and intimate forms of communication.
I enjoy reading this paper since the following respects:
- It's kind of related to carewall, the project we're trying to work on.
- It points out the problem I wanna solve before: "it felt important to us that people could actually look into each other's eyes, so the camera was placed right in the middle of the screen." But the black dot is not natural. I haven't thought any good ways to solve. -> However, they points out "the majority of the people didn't think about the camera at all." (Really? I wanna try!)
- Interesting idea: "By moving forward or backward, people alter not only their own image but also the image of the remote persons." => But I wonder how smooth the image will be.
- The sharing smae space idea is a little bit horrifying, I think.

(C6 Attentive objects) Pattie Maes, Attentive Objects: Enriching people's natural interaction with everyday objects, INTERACTIONS, 7~8, 2005.

attentive object:
- to make people's lives more convenient - by augmenting objects with sensors, communication and computation, and by using intelligent interface techniques to predict what a person may be interested in.
- to enrich people's natural interaction with everyday objects, to enrich (even enlighten) people's live
I'm looking forward to "interact" with objects - life should be different and more convenient throught this way :)

(C7 Smart chair) S. Mota and R. W. Picard (2003), Automated Posture Analysis for Detecting Learner's Interest Level, Workshop on Computer Vision and Pattern Recognition for Human-Computer Interaction, CVPR HCI, June, 2003.

It provides a system for recognizing naturally occurring postures and associated affective states related to a child's interest level while performing a learning task on a computer.
I think the most difficult part is to recognize posture and interpret, i.e. activity recognition is quite challenging.
Combining with other signals is quite important! e.g. facial expression, etc.

(C1 Context-awareness survey) G. Chen, D. Kotz, A Survey of Context-Aware Mobile Computing Research, Technical Report TR2000-381, Department of Computer Science, Dartmouth College, November 2000.

Context is the set of environmental states and settings that either determines an application's behavior or in which an application event occurs and is interesting to the user.
Context-aware computing is a mobile computing paradigm in which applications can discover and take advantage of contextual information (such as user location, time of day, nearby people and devices, and user activity).
two definitions of context-aware computing:
- Active context awareness: an application automatically adapts to discovered context, by changing the application's behavior.
- Passive context awareness: an application presents the new or updated context to an interested user or makes the context persistent for the user to retrieve later.

Afterthoughts: This survey paper is really helpful since it discusses definitions and also introduces many related works to context-aware computing, helping us not only understand what it really is but also know more about current works. Context-aware computing is indeed important in Ubicomp - we should establish clear concepts to it.

(C2 Sensors survey) Michael Beigl, Albert Krohn, Tobias Zimmer and Christian Decker, Typical Sensors needed in Ubiquitous and Pervasive Computing, First International Workshop on Networked Sensing Systems (INSS) 2004, Tokyo, Japan, June 22-23. 2004.

sensors (in small & cheap devices): capture physical parameters from the environment or objects => input to functions => determine general contextual information.
7 general types of sensors:
- movement
- light
- force
- temperature
- audio
- humidity
- proximity/activity
primary restrictions: form factors & energy consumption
Afterthought: Very interesting! It draws clear and useful classifications of sensors for Ubicomp, making me start to think about objects surrounding me: How do I sense important info? With what kind of appropriate devices? In what way can I implement? etc.

- my slides
- This paper: good for us to understand main ideas and spirits of Ubicomp, and also realize design and implementation issues.
- It seems that if we want to have a new design of Ubicomp, we will be limited by or have to counter hardware issues first. No wonder there are also some discussions about how can we design to make users feel easy to change Ubicomp objects. (e.g. u-Texture: Self-Organizable Universal Panels for Creating Smart Surroundings, Ubicomp 2005)
- However, if we are limited by hardware problems, it is possible that interesting designs will be only ideas. (e.g. Jackie Lee from MIT media lab: physical Word.)
- It is important to understand the history of the field you want to research.

Discussion:

What does it mean for a computer to disappear?

Physical V.S. feeling
Complexity: present給人用的方式感覺
Object展現的方式、樣子 is very important(affordance, e.g. door – you know how to open it)
If computers are as mature as motors, it will be nature

Weiser: focus on user ability, instead of strong computing
less about performance, but principles on applying to daily life
also a trade-off: hope that we can use little attention but achieve high performace/output/work
