20120274609 | METHOD AND APPARATUS FOR ACTIVE ULTRASONIC TOUCH DEVICES - A system for determining a user indication is disclosed. The system includes a communication interface configured to send a signal to be used to propagate a freely propagating signal through a propagating medium with a surface and receive the freely propagating signal that has been disturbed by a disturbance on the surface. The system also includes a processor coupled to the communication interface and configured to process the received signal to determine a user indication associated with the disturbance. | 11-01-2012 |
20130127755 | LOCALIZED HAPTIC FEEDBACK - A haptic feedback system is disclosed. The system includes a plurality of remote transmitters that are remote from a location of interest on a surface of the system. The system includes a signal generator that generates a signal for each of the remote transmitters. The remote transmitters propagate the signals through a medium of the surface and the signals interfere at the location of interest such that a localized disturbance is generated at the location of interest. | 05-23-2013 |
20130141364 | USER INTERFACE INTERACTION USING TOUCH INPUT FORCE - Providing a user interface interaction is disclosed. A first set of one or more indicators associated with a first location on a touch input surface and a first force intensity of a touch input provided on the touch input surface is received. A user interface object associated with the first location is determined. A second set of one or more indicators associated with a second location on the touch input surface and a second force intensity of the touch input that has been in continuous contact with the touch input surface at least since the touch input was provided at the first location is received. The user interface interaction based at least in part on the user interface object, the first set of indicators, and the second set of indicators is provided. | 06-06-2013 |
20130141365 | DETECTING TOUCH INPUT FORCE - Detecting a touch input force is disclosed. A signal to be used to propagate a propagating signal through a propagating medium with a surface is sent. The propagating signal that has been disturbed by a touch input with an amount of force on the surface is received. The received signal is processed to determine an identifier associated with the amount of force. | 06-06-2013 |
20130141396 | VIRTUAL KEYBOARD INTERACTION USING TOUCH INPUT FORCE - Providing a virtual keyboard interaction is disclosed. An indicator identifying a force intensity of a touch input provided on a touch input surface is received. It is determined that the touch input is associated with a virtual keyboard. A virtual keyboard interaction is provided based at least in part on the indicator identifying the force intensity of the touch input. | 06-06-2013 |
20130142362 | CONTROLLING AUDIO VOLUME USING TOUCH INPUT FORCE - Controlling an audio volume is disclosed. An indicator identifying a force intensity of a touch input provided on a touch input surface is received. It is determined that the touch input is associated with an audio volume control. The audio volume is controlled based at least in part on the indicator identifying the force intensity of the touch input. | 06-06-2013 |
20140022189 | TOUCH INPUT SURFACE SPEAKER - Processing an audio signal is disclosed. A source audio signal to be rendered by a touch input medium is received. An indication of an event where the touch input medium has been contacted at a location on the touch input medium such that rendering of the source audio signal by the touch input medium is affected by the contact is received. At least a portion of the source audio signal is modified based on an expected effect of the contact on the touch input medium determined using the indication of the detector. | 01-23-2014 |
20140023210 | TOUCH INPUT SURFACE MICROPHONE - Processing an audio signal is disclosed. The audio signal is received from a sensor coupled to a touch input medium. An indication of an event where the touch input medium has been contacted at a location on the touch input medium is received. The event has been captured as an audio signal component of the received audio signal. At least a portion of the audio signal component is reduced from the audio signal. | 01-23-2014 |
20140078112 | USING MULTIPLE SIGNALS TO DETECT TOUCH INPUT - Detecting a location of a touch input is disclosed. Each of a plurality of transmitters coupled to a propagating medium emits a signal that is distinguishable from other signals emitted from other transmitters. The signals from the transmitters are received from at least one receiver coupled to the propagating medium to detect the location of the touch input on a surface of the propagating medium as indicated by an effect of the touch input on each of the distinguishable signals. | 03-20-2014 |
20140247230 | DETECTION OF TYPE OF OBJECT USED TO PROVIDE A TOUCH CONTACT INPUT - Determining a touch contact object type is disclosed. A signal detected due to a touch input object contacting a touch input surface is received. At least a portion of the received signal is compared with one or more signatures of one or more touch input object types. A type of the touch input object contacting the surface is determined based at least in part on the comparison. | 09-04-2014 |
20140247250 | DETECTION OF A NUMBER OF TOUCH CONTACTS OF A MULTI-TOUCH INPUT - Determining touch contact locations is disclosed. A signal that has been disturbed by touch contacts of a touch input on a surface is received. The received signal is transformed to determine a spatial domain signal. The spatial domain signal is compared with an expected signal associated with potential locations of sources of disturbances caused by the touch contacts. The locations of the touch contacts of the touch input are determined based at least in part on the comparison. | 09-04-2014 |
20150070597 | ATTACHING ELECTRICAL COMPONENTS - A touch input device is disclosed. The touch input device includes a touch input medium configured to receive a touch input. The touch input device includes a conductive trace coupled to the touch input medium. The touch input device also includes a transducer electrically coupled to the conductive trace and coupled to the touch input medium via a non-conductive adhesive. | 03-12-2015 |
