3. Functionality Integrating Context Awareness in mobile group communication Multimedia messages with sound and videos Permanent local storage of the messages Project – Goals ‘Supporting Collective and Collocated Use of Contextual Media’ • Create a system that enhances mobile media sharing with context awareness and features for collocated interaction • Create a system that is unique with no commercial or academic substitutes • Create a robust system that can be trialed in the field with at least 8 users Quality • Implement immediacy (instant messaging) • Interaction design • Crossmedia: access to media also through the web • Research logs

4. Media story based messaging time based or threaded message listing simple media stories meta-data with context information static creation information Dual-media messages text & images simple message meta-data with context information Basic user information Online/offline status Remote permanent storage for content (mGroup server) content read from the server storage mGroup - Mobile Group Media
