Organisation
o 2 complementary teams at France Télécom R&D:
1. Development of telemedicine services prototypes
2. Research on haptic interfaces and tele-gesture
o External partners1. Universities: robot control2. Industrials: making of robot device3. Medical staff: clinical validation

Architecture of the service
o Point to point service linking:1. a « patient » site: Patient + medical
personnel, video, robot, US device
2. an « expert » site: Medical expert, visio, haptic device, image visualisation
o Different Flows … and constraints:
1. Informal communication: Audio/video
2. Diagnosis: Medical images
3. Robot control and gesture: Haptic data

Flow Management
1. Integration of all the flows on one hardware platform2. Handling of the requirements specific to each flow
(delays, rates, priority)3. Handling of the necessary dependency between
flows (synchronisation)4. Modularity -> ISDN, ADSL, ATM, GPRS, UMTS

Transmission of Touch
o use of robotics for robot tele-operation and haptic for “rendering” the force exerted by the robot.
o The transport of the gesture data allows an immersion even more complete and realistic for distant manipulators.
o The haptic command station preserves medical expert proprioception and gesture feelings
