Locational Affinity Awareness for BAN Applications <month year> doc.: IEEE 802.15-<doc#> March, 2008 Locational Affinity Awareness for BAN Applications Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Purpose To describe the necessity of locational affinity awareness for the various BAN applications Seung-Hoon Park, Samsung <author>, <company>

Locational Affinity Awareness <month year> doc.: IEEE 802.15-<doc#> March, 2008 Locational Affinity Awareness Recognize the degree of affinity between two nodes in the locational point of view according to the measured parameters related of the physical proximity such as distance, touch, direction, etc It may take time in measuring these parameters to get a certain recognition level Seung-Hoon Park, Samsung <author>, <company>

Locational Affinity Awareness <month year> doc.: IEEE 802.15-<doc#> March, 2008 Locational Affinity Awareness Function A kind of context awareness Automatic connection setup User select an appropriate recommended connection Objectives To lighten loads for connecting proximate BAN devices manually Locational affinity to help context-aware services Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Applicable Cases Medical Patient monitoring or examination [1] Non-medical E-charm [2] (personal item tracking) Smart key Game application Social networking service Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Connection Setup Features When two nodes encounter in the body-around range, the connection to exchange the temporary data should be established by the unconscious way Methods Neighbor node discovery Fast hand-shaking Seung-Hoon Park, Samsung <author>, <company>

March, 2008 Measurement Seung-Hoon Park, Samsung

Encounter related parameter <month year> doc.: IEEE 802.15-<doc#> March, 2008 Encounter related parameter The ratio of encounter The pattern of encounter The type of encounter Normal Touch Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Touch Awareness Features To recognize the close intimacy the type of encounter (Normal, Touch) Very powerful function for easy and intuitive connection setup of BAN devices BAN system can distinguish the on/in-body node from the around-body node Method Human body communication Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Distance Awareness Features The distance between two nodes is measured The degree of affinity can be inferred from the measured distance Method Fine ranging technique Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Direction Awareness Features Recognize whether the conversation is in the face-to-face condition or not Methods RF technology Geo-magnetic sensor Vision/image processing Others? Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Privacy and Security Automatic connection setup for the locational affinity awareness is not secure Authentication should be done for some use-cases An application considering user privacy a group-aware application making a random encounter into authenticated one Identification may be inevitable to get higher security Seung-Hoon Park, Samsung <author>, <company>

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> March, 2008 Conclusion Locational affinity awareness is required for some BAN applications Required Techniques Neighbor node discovery & hand-shaking Ranging Human body communication Authentication or identification Seung-Hoon Park, Samsung <author>, <company>
