Proactive Displays “Displays will be everywhere” –What will we do with them? –What will they do for us? How can displays sense & respond appropriately to the people & activities taking place nearby? –Context –Content –Interaction models

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 content is stored in backend infrastructure Environment detects identifier (e.g., RFID, Mote) Environment computes personal profile x content and displays 1. Various Identifiers

Models for Proactive Displays Personal profile stored on personal device; Contextual content stored in infrastructure Content descriptor is sent to the personal device Your personal device computes personal profile x content and sends result for display 1.Content Descriptor 2.Selected Content Privacy management

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?
