3. Personal Space • Term “Personal Space” • Originated from social psychology • The region surrounding a person which they regard as psychologically theirs. • The notion of personal space comes from Edward T. Hall “The Hidden Dimension (1966)”, • Intimate space < 1.5 feet • Personal space < 4 feet • Social space < 12 feet • Public space < 25 feet • Invasion of personal space often leads to discomfort, anger, or anxiety • Personal space is also affected by a person's position in society with more affluent individuals demanding a larger personal space Source : Wikipedia ETRI

4. Personalized Space • Personalization involves using technology to accommodate the differences between individuals. • Personalization implies that the changes are based on implicit data. • eliminate repetitive tasks; recognize habits and shorten the path to engage in such habits • provide more specific information that is increasingly relevant to a person’s interests; replace “average” information with information specific to that person’s environment • provide one-stop services; accommodate unique personal preferences Source : Wikipedia ETRI

5. Requirements for the Personalized Space • Personalization of space • Make public space react differently between individuals based on implicit data • Feel the space within reach of any limb of an individual. • Public space into personal space • Exchange implicit data and explicit control among human & things in the public space of an individual • Profile based, behavior based, collaboration based • Requirements of communication for personalized space • Group based communication in public space • Number of communicators in public space will increase dramatically • Guarantee the various quality of service at once ETRI

6. °C °C Public Space & Personalized Space ETRI

7. Specification of the Personalized Space • Radius of public space which will be converted personal space • Sphere with 25 feet radius • Number of communicators involving a collaboration for the personalized space • Gradually increasing from 3~4 to 60~80, or even more ? • Communication type • peer-to-peer, 1-n, n-1 • n-m group-cast (group-chat) • Traffic characteristics • delay tolerant data, real-time control, audio/video stream ETRI

8. Architectural View of the Personalized Space • Independent personal space • Communicators in public space are involving to collaborate with no need of supporting from outside of the public space • Communications within public space • Inter-related personal space • Space is inter-related with the pre-defined spaces • Information for collaboration needs to be provided from outside of the public space • Communication to outside of the public space • Chased personal space • Personalized spaces are following to an individual • Communication between consecutive public spaces ETRI

10. Communication for the Personalized Space • Public space communication • n-m groupcast • at least 25 feet range • nx10 bps ~ m Mbps throughput • ms ~ min latency • Area access communication • Getting to database through core network • Wired or wireless network • Space chasing communication • interonnection between public spaces • nx10 bps ~ m Mbps throughput • ms ~ min latency ETRI

11. Candidate Technologies for the PSC • Public space communication • Bluetooth • ZigBee • UWB • … • Area access communication • Cable Network, Telephone Network • WiFi • Cellular Network • Space chasing communication • Interconnected through area access network • Hand-over between public spaces ETRI

12. Scope of the PSC project • Public space communication • n-m groupchat, nx10 bps ~ m Mbps, ms ~ min • One fits for all • MAC only • Need new PHY & MAC • Area access communication • Use as it is • Space chasing communication • Hand-over between public spaces • Managed on MAC layer ETRI
