Towards an accurate gesture and body movement estimation using very-small and low-power wearable sensor nodes
The BoWI project stands for Body Wold Interactions and initially stems from a proposal of the CominLabs think tank focused on the society challenge called Digital Environment for the Citizen. It is also related to the social challenge ICT for Personalized Medicine and to the research track Energy Efficiency in ICT. The main objective of the project is the design of pioneer interfaces for an emerging interacting world based on smart environments (house, media, information and entertainment systems…). Basically the project relies on Wireless Body Area Sensor Networks; the aim is the accurate Gesture and Body Movement estimation with extremely severe constraints in terms of footprint and power consumption according to on-body energy harvesting perspectives. The BoWI geolocation approach will combine radio communication distance measurement and inertial sensors and it will also strongly benefit from cooperative techniques based on multiple observations and distributed computation. Different types of applications, as health care, activity monitoring and environment control, will be considered and evaluated along with a human-machine interface expertise.
The first scientific challenge is global and deals with the solution to be interactively invented by all partners: a short-range geolocation method based on distributed and coopering devices processing multisource data issued from radio-communication distance estimation and integrated inertial sensors. It includes several specific contributions:
In practice the BoWi partners aim to deliver the design of basic components, a prototype based on available radio front-ends and energy harvesting devices as well as a system simulator including mm-wave models. Results will also concern the specification of future radio-front ends.
The BoWI team is composed of academic staff of University of Rennes 1, INRIA, UBS University and Telecom Bretagne, members of three CNRS labs located in Brittany IRISA (Lannion, Rennes), IETR (Rennes) and Lab-STICC (Brest, Lorient, Vannes).
