20120274610 | INTERACTION SURFACES - An input apparatus has an interaction surface, an acoustic transmitter located adjacent the surface, an acoustic receiver located adjacent the surface and across the surface from the transmitter, and a processing environment. It is configured to transmit an acoustic signal(s) from the transmitter and to receive the signal or signals at the receiver. It detects the presence of an input object adjacent or touching the interaction surface by detecting an increase in the minimum time of flight, through air, of at least a part of the signal(s). | 11-01-2012 |
20130094329 | CHANNEL IMPULSE RESPONSE ESTIMATION - A human-machine interface system adapted to track movement of an object in air is disclosed. In one aspect, the human-machine interface includes an acoustic transmitter, an acoustic receiver, and logic configured to apply a calculated inverse matrix of an impulse signal transmitted by the acoustic transmitter to a signal received by the acoustic receiver, wherein movement of the object is used to control the machine. | 04-18-2013 |
20130176258 | MOTION FEEDBACK - A user input to a system is processed by receiving reflections of signals from a moving input object. Information relating to the direction of movement of the input object and information relating to the speed of the input object are determined from the reflections. Continual sensory feedback is provided to the user, controlled by a parameter that is repeatedly updated based on the direction and speed of the input object. When no new determination of information relating to the speed or direction of the input object has been made since a previous update, a time-dependent change is made to the parameter. | 07-11-2013 |
20140029384 | USER INTERFACES FOR ELECTRONIC DEVICES - An electronic device comprises a transmitter | 01-30-2014 |
20140176467 | TOUCHLESS INTERACTION - A portable electronic device comprises means | 06-26-2014 |
20140306936 | TOUCHLESS INTERACTION DEVICES - An electronic device comprises a front surface comprising a display screen; a rear surface; at least one ultrasonic transmitter; and at least one ultrasonic receiver. The device may be configured to transmit signals from the transmitter and to receive the signals at the receiver after reflection from an input object and to use the reflected signals to characterise the motion of said input object for controlling a function of the device. At least one of the ultrasonic transmitter and the ultrasonic receiver is disposed on the rear surface of the device. The device may be configured to transmit signals from the transmitter and to receive the signals at the receiver after reflection from a user's hand and to use the reflected signals to detect one of a predetermined set of gestures carried out adjacent to the device when the device is placed on its rear surface on a flat supporting surface. | 10-16-2014 |
20140320390 | OBJECT AND MOVEMENT DETECTION - Motions, positions or configurations off, for example a human hand can be recognised by transmitting a plurality of transmit signals in respective time frames; receiving a plurality of receive signals; determining a plurality of channel impulse responses using the transmit and receive signals; defining a matrix of impulse responses, with impulse responses for adjacent time frames adjacent each other; and analysing the matrix for patterns ( | 10-30-2014 |
