Abstract (en)
[origin: WO2018069607A1] This device for locating an impact (P) against a transparent interactive surface (12) comprises at least three transducers (PTA, PTB, PTC, PTD) distributed against the transparent interactive surface (12) and at least one computer (14) programmed to locate the impact (P) by analysing differences in the propagation times of travelling mechanical waves coming from the impact (P) towards the transducers (PTA, PTB, PTC, PTD) on the basis of detection instants of the impact (P) that are identified in electrical signals supplied by the transducers. The device further comprises: a protective housing (10), rigidly connected to the transparent interactive surface (12), intended to accommodate at least one portion of an electronic device (16) with a display screen (18) so as to place the display screen (18) facing the transparent interactive surface (12); means (22) for adjusting the display screen (18) so that it can be centred on a marker (R) produced by a marking on the transparent interactive surface (12); and a computer (14) programmed to convert the location of the impact (P) in the transparent interactive surface (12) into a location of the impact (P) in the display screen (18).
