Pint-sized Proactive Displays

• Convergence of Motes & Displays– Mote processor + radio + LCD– Ultra low power– Future: bi-stable, color, reflective displays

Models for Proactive Displays

• Personal profile + contextual contentis stored in backend infrastructure

• Environment detectsidentifier (e.g., RFID, Mote)

• Environmentcomputes personal profile x contentand displays

1. VariousIdentifiers

Models for Proactive Displays

• Personal profile stored on personal device;Contextual content stored in infrastructure

• Content descriptor is sentto the personal device

• Your personal devicecomputes personal profile x contentand sends resultfor display

Experience UbiComp Project

• Why focus on conferences (e.g., UbiComp)?– Restricted context(s)

• Paper/Poster/Demo sessions, Breaks, Lunch, Reception

– Content is available• Registration info (badges), homepages

– Desire to reveal details about yourself• Show & tell, learn about others & their work

Who is this guy (and why is he asking that question)?

What poster should I see next?(Trip Report: what posters did I see?)

What do we have in common?

Challenges

• Identification & Tracking– RFID, Motes, Personal Server, other handhelds/wearables, …

• Profiles– What does a profile look like?– Where does it come from (explicit / implicit)?– Privacy management

• Contextual Content– What is displayed (in different contexts)?

• Interaction Models– Proactive, interactive, hyperactive, …

• Evaluation– [How] will we have enhanced the UbiComp Experience?
