3. January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide3 Purpose and Contents The purpose of this presentation is to discuss possible uses case for BAN networks. Contents –Categorization of BAN devices Wearable high data rate (HDR) devices Wearable or implanted low data rate (LDR) devices –HDR and LDR uses cases –HDR and LDR devices on a unique network –Technical requirements –Conclusion

Need to be "forgettable" (no battery to charge, no maintenance) Requirement are => very low power (energy scavenging) and very simple network subscription / unsubscription

January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide6 LDR applications : Health monitoring Mainly composed of : –A network of sensors (move, heart rate, blood pressure distributed on or inside the body). –A gateway that collect those data and forward them to a doctor is something get wrong.

January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide9 Music or movie The interfaces is distributed on several devices –Video glasses are used for display (movie & player interface) and audio. –The wrist movement sensor allow navigation in the interface. Thanks to the microphone the player is able to cancel environmental noise and adapt the volume. Some music can be downloaded via the cell phone Medical and movement sensors allow the system to adapt his behavior to user contextual information's

January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide10 Communication The interface is distributed on several devices –Phone screen can be displayed on the video glasses (video call, mobile internet) or on the watch screen. –Audio is diffused by glasses earphone –User interface rely on the watch and vocal recognition for hand-free internet browsing –A BAN-enabled pen will permit to write e-mail or sms by natural writing. Pedestrian GPS navigation will be improved by feet motion sensors Various motion sensors and video glasses will permit new online videogame User contextual information's allow cognitive behavior of the interface like : –Warn if you are about to leave home whiteout your key –Detect that you are about to forget your passport in the plane

11. January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide11 In your car The phone provide GPS and traffic info to the car navigation system Destination can be extracted from the smartphone contact database The GPS Map and car date are displayed in the glasses (HUD like) Music can be diffused through the audio car system when the player interface uses the video glasses and the wrist sensor. Music can be adapted to the ambient noise and traffic conditions. Medical sensor will allow the car to generate an alarm if the driver become sleepy

12. January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide12 Cognitive behavior ? This means "gather as much contextual informations as possible and adapt consequently" –This include basic things like "automatically switch to silent mode during a scheduled meeting" –This can fuse several kind of datas like : The guys is running (from movement sensor) He has to take a train in 10 minutes (from agenda) We are still fare away of the stations (GPS position)  It seems that we will miss this train The system can then automatically take some complex actions Refuse by default any incoming call (no time to answer) Check online if the train is on-time and retrieve his track number Check online the timeplan, price and exchange possibility for a next train. Compute and propose the fastest way to go to the station Check if we still have some hope to catch this train If not, propose to cancel the ticket an get new one for the next train

13. January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide13 Technical requirements Network mechanisms –We need a very flexible network with automatic subscription / unsubscription mechanism : you don't want to reconfigure your network each time you change your shoes. –Strong security is mandatory : you don't want to broadcast you agenda (HDR devices) as well as the data of your medical sensors (LDR devices) Physical Layer –Maximal ranges is about 2 m –Need high flexibility in Data rates : (from 10 kbit/s to 10 Mbit/s) Energy consumption : HDR devices may be recharged but embedded LDR devices need to be self-sufficient –Every devices (LDR, HDR and implant) need to be able to communicate on a unique network with a kind of "universal" air interface.

14. January 14, 2007Doc: IEEE 802.15-07-0536-00-0ban Jean Schwoerer (France Telecom R&D) Slide14 Conclusion A BAN include a lot of sensors (medical, motion, environmental) Personal objects like smartphone,or PDA contains a lot of data (contact, agenda) A cellphone is the BAN gateway to the outer world A BAN as the unique opportunity to unify all those devices This will change the way we interact with our electronics tools This can lead to a lot of context-aware applications that will make life easier
