Abstract:
A simplified touch screen system that can sense when an object is held in continuous direct or indirect contact with a transparent substrate of the touch screen system as well as determine a location (e.g., X, Y coordinates) of the object in relation to the transparent substrate. The touch screen system employs capacitance technology to sense whether the object is held in contact with the transparent substrate and acoustic sensing technology to determine a position of the object that is contacting the transparent substrate. The touch screen system requires a reduced number of shielding and isolation layers to be deposited upon the transparent substrate, partially because the touch screen system utilizes a bezel associated with an underlying display to provide shielding against electromagnetic radiation emitted by the display.
Abstract:
An air mouse system is described. The air mouse is configured to periodically transmit RF signals in order to trigger a plurality of ultrasonic transmitters arranged on a television. The ultrasonic transmitters transmit ultrasonic signals when being triggered by the RF signals from the RF trigger. An ultrasonic receiver receives the ultrasonic signals. A processor calculates a location of the air mouse with respect to the ultrasonic transmitters based on time differences of the ultrasonic signals transmitted by the ultrasonic transmitters arriving at the ultrasonic receiver. A series of locations of the air mouse forms a motion trail of the air mouse and the air mouse transmits the motion trail to the television wirelessly. The motion trail is projected as a cursor trail on the television screen by the television, to control the cursor on the television screen by virtue of the motion of the air mouse.
Abstract:
A system for classifying touch events includes a touch screen configured to display an interactive element, one or more vibro-acoustic sensors coupled to the touch screen, a touch event detector configured to monitor the one or more vibro-acoustic sensors and to save vibro-acoustic signals sensed by the one or more vibro acoustic sensors, wherein the touch event detector is further configured to detect touch events in which the interactive element is touched by a first or a second finger part of a user, and wherein the touch events result in generating the vibro-acoustic signals, and a vibro-acoustic classifier configured to classify the vibro-acoustic signals.

Abstract:
A portable measurement system is provided comprising a probe, two trackers, a receiver and a pod. A user interface control captures a location and position of the probe in a three-dimensional sensing space with respect to a coordinate system of the receiver from time of flight waveform analysis. The system suppresses a ringing portion of the received ultrasonic and minimizes distortion associated with ultrasonic transducer ring-down during high-resolution position tracking of the probe and the two trackers. Media is presented according to a customized use of the probe and two trackers during an operation workflow.
Abstract:
A sound wave touch pad includes a housing provided with a plurality of grooves. A pad is exposed on a surface of the housing and inserted into a groove of the housing. The pad is further configured to generate a sound wave when an external force is generated. A sound wave sensor is provided inside the housing and is configured to receive the sound wave generated from the pad
Abstract:
A display input device according to one aspect of the present disclosure includes display portion, piezoelectric element, drive portion, and detection portion. The display portion includes touch panel that detects touched position on display surface. The piezoelectric element is provided on touch panel and vibrates touch panel. In response to touch panel being touched, drive portion applies a voltage to piezoelectric element to vibrate piezoelectric element. The detection portion detects the voltage value of a voltage generated in piezoelectric element by a pressure being applied to piezoelectric element when touch panel is touched. The smaller the voltage value detected by detection portion is, the larger the voltage applied to piezoelectric element by drive portion for vibrating piezoelectric element is. The larger the voltage value detected by detection portion is, the smaller the voltage applied to piezoelectric element by drive portion for vibrating piezoelectric element is.
Abstract:
The motion of an object is characterized by transmitting acoustic signals over first and second transmitter-receiver channels. Information relating to signals received over the first channel is compared with information relating to signals received over the second channel, to identify a similar pattern in both channels arising from reflections from the object. A relative timing difference between the channels, associated with the similar pattern, is used to characterize the motion of the object.
Abstract:
