  2. 2. Overview Interrelativity develops software that integrates sensing and display technologies with online personal content and promotional content to help people relate to one another in shared physical spaces Bringing the best of virtual communities to physical spaces. 3 The Problem We are social: fundamental need for a sense of belonging We are shy: 48% of US population is chronically shy We want to relate to and connect with others, but are often unable or unwilling to do so Even at times and places specifically designed to encourage connections (“third places”) (“ places” 4 2

  24. 24. Looking forward Three key issues for Proactive Displays Context Where should they go? – Trust, desire to relate to others – Macro & micro Content What should they show? – Type: images, text, video, audio, … – Storage: local vs. remote Control How will they know? – Implicit vs. explicit revelation – Anonymity vs. accountability 47 Policy, Legal & Ethical Issues Content Copyright issues Offensiveness Contexts Liability Ownership of Sensor data Physical association with digital content Risks (& rewards) Accountability 48 24
