Hear&There An Augmented Reality System of Linked Audio Joey Rozier Karrie Karahalios and Judith Donath Sociable Media Group MIT Media Lab ICAD 2000 Conference - April 3, 2000
Overview Project Purpose and Goals Brief Scenario Basic Augmentation Details Hardware Authoring and Playback Security and Privacy
Purpose and Goals Augment Environment with Audio –Augmented Reality (or Mixed Reality) Develop Social Augmentations –Oral Histories –Focus on Authoring Activation Networks - Linking Self-Contained and Portable Limit Use of Visual Cues
Example Scenario Augmented Boston Common Can hear audio “left behind” (maybe history) Guided towards related audio (moo...) Author can add his/her own sound Others are unaware
Augmentation Details The SoundSpot –Basic unit of augmentation –Any type of audio (voice, music, whatever) –“Placed” at a specific location (longitude/latitude) –Has a specified size –Other audio properties (braids, etc.) –User walking “into” SoundSpot hears it
Playback: Basics User dons system Very simple start-up Moves through environment Hears sound tied to location
Playback: Spatialized Sound Each sound “appears” to be coming from center of a SoundSpot Java 3D API Compass attached to headphones Do not deal with environment effects (enclosed spaces, etc.) Future work will improve spatialized sound
Playback: Two Modes Explorer –All SoundSpots activated –Can be very cluttered –Ultimate control with listener Activation Networks
Playback: Activation Networks For Linking and Organizing Sounds Author creates Link Categories –e.g. My Family, About Media Lab Author associates Link Categories with a SoundSpot User can activate Link Category when standing in SoundSpot StartSpots
Playback: Activation Networks Example StartSpot in Boston’s Public Garden –Link Categories SMG: SMG SoundSpots Weeping Willow: interesting SoundSpots about weeping willow trees My Favorites: my favorite SoundSpots –When entering StartSpot, activate “Weeping Willow”; now those “exist” –Weeping Willow spots may have their own LinkCategories
Playback: Directing the User Palm Interface –Easy, intuitive –But uses visual information! Audio Beacons?
Security and Privacy Authentication for Authors Open System for Users Wireless Connection to Server?
Future Work Finish Implementation! More Portable System Temporal Information Other forms of audio augmentation
