Abstract: In a system and method for facilitating wireless communication between agents in a wireless network, each agent is equipped with an agent's device using a main wireless infrastructure and a separate auxiliary wireless infrastructure. Initial contact between any first agent's device and any other agent's device is made within the auxiliary wireless infrastructure, whereas, once this initial contact has been established, all ensuing communications between the first agent's device and the other agent's device take place within the main wireless infrastructure.

Abstract: In a system and method for facilitating wireless communication between agents in a wireless network, each agent is equipped with an agent's device (10a, 10b) using a main wireless infrastructure (2) and a separate auxiliary wireless infrastructure (1). Initial contact between any first agent's device (10a) and any other agent's device (10b) is made within the auxiliary wireless infrastructure, whereas, once this initial contact has been established, all ensuing communications between the first agent's device (10a) and the other agent's device (10b) take place within the main wireless infrastructure.

Abstract: The method obtains a signature (S) of a gesture produced in free space, e.g. for producing gesture recognition commands, by deriving at least one time-evolving signal representative of muscular activity involved in producing the gesture and determining at least one value of a parameter yielded by that signal. The method comprises the steps of: time dividing the time-evolving signal (14) into sub-frames (SF1, SF2, . . . ), and for at least one sub-frame: determining at least one parameter value (Psfi) yielded by the signal over at least a part of that sub-frame, and expressing said parameter value as a component of a vector (S) along a dimension thereof specifically allocated to that sub-frame (SFi), the resultant vector yielding the signature (S) of said gesture. The invention also relates to an apparatus producing such signatures and commands by gesture recognition.
