The objective:

The problems:

Build interactive systems that involve multiple locations and various input/output devices

• Access to hardware very difficult• Network programming is a pain• Synchronizing software and hardware• Often difficult to get overview of devices

Introduction: What are Phidgets?1

Phidgets are hardware building blocks to create tangible interfaces:

They can for example …

Interface Kit + Sensors Servo Motor RFID Reader Text Display

… provide buttons/sliders for interaction … move objects … identify objects … display messages

LINC: A Digital Family CalendarCarman Neustaedter1, A.J. Brush2, and Saul Greenberg1

1: University of Calgary, Canada, and 2: Microsoft Research, USAcarman@cpsc.ucalgary.ca, ajbrush@microsoft.com, saul.greenberg@ucalgary.ca

Design: LINC was designed using a participatory design process involving twenty primary schedulers. Design stages included: low-fidelity paper prototype design sessions, the design of a medium-fidelity digital prototype, and a formative evaluation. Findings guided the design of a high-fidelity prototype of LINC.

A digital calendar that is as easy to use as a paper calendar and available where families need it: home, work, or on the go.

Shared by Family

Always-on and Inkable

Mobile Access

Work Access

Evaluation: Four families were given LINC running on a slate tablet for our month long field study. All adopted LINC and used it extensively as their primary family calendar. They valued the portability of the tablet, the ability to access their calendar from multiple locations, and the ease in which they could personalize their calendar with ink and color.

Screen Sharingwithin the Community Bar

Kimberly Tee, Saul Greenberg, and Carl Gutwin

What the person sharing seesEach person sharing their screen can control how much others see

Specify what to share, how often to update the shared screen image, and how much detail to share

What others seeOthers can see shared screens in miniature or raise the larger view to see more detail

Zoom and pan to view another’s screen in more detail

Moving to interactionTelepointers can be used to remotely point at an artifact on another’s screen

Screen Sharing Item

Initial experiencesTen co-located and distributed Community Bar

users from our research group shared their

screens on Community Bar.

They used our tool to:

– maintain awareness of what others were doing

– monitor progress and coordinate joint tasks

– determine when others could be interrupted

– engage in serendipitous collaboration

– project a certain image of themselves

People balanced awareness with privacy by using

our built-in privacy protection strategies.

Screen sharing helps people maintain awarenessof what others are working on.
