BoWI opens new, unexplored opportunities for interactions between users (inter-BoWI), and between\u00a0users and the environment. Original use cases have been proposed to test the BoWI systems.\u00a0Considering the possibility to identify posture with low-cost low-power resources, the BoWI team came up with three proposals related to posture recognitions<\/p>\n
Combinatorial alphabet<\/h4>\n
The first one (Fig. 1) is the proposal of a combinatorial alphabet of gestures that can be used for\u00a0any control. This idea has two three advantages. First the combination of local simple libraries (ARM, LEG, …)\u00a0gives a huge number of possible postures. Secondly, each local gesture can be identified with precomputed\u00a0signatures that make the discrimination of gestures easier in noisy contexts. Finally the library is meaningless,\u00a0so general, and can be exploited for different types of control.<\/p>\n

Imitation game<\/h4>\n
The second case (Fig. 2) study is a game inspired by the famous toy of the eighties called “Simon”.\u00a0Here the idea is that each player must redo the list of previously registered gestures and add a new one.\u00a0<\/span>The registration and the control is performed by the BoWI system. This game can also be used to populize\u00a0the BoWI Gesture Alphabet.<\/p>\n Fig. 2: Gestural “Simon” game.<\/p><\/div>\n The third case study is the registration of daily gestures to be analysed by physician or occupational therapists.\u00a0Many very practical applications will benefit from this case study such as the monitoring of position at work,\u00a0the monitoring of elder people at home or for functional rehabilitation at home.<\/p>\n Fig. 3: Remote, everyday monitoring.<\/p><\/div>\n SIMON (user vs. Computer)<\/strong><\/p>\n Low cost Outdoor motion capture: BoWI BAN (player gestures) + 2 or 3 \u00a0BoWI nodes as fixed beacons around the field \u00a0(geolocation)<\/p>\n<\/div>\n Social network<\/strong>: share emotion with gestures<\/p>\n<\/a>Functional rehabilitation<\/h4>\n
