An apparatus comprising: an image processor configured to determine at least one image parameter with respect to at least one image displayed on at least one display; a touch controller configured to determine at least one touch parameter with respect to the at least one display configured to display the at least one image; and a tactile effect generator configured to generate at least one tactile signal based on the at least one touch parameter and the at least one image parameter.

Acoustic touch detection (touch sensing) system architectures and methods can be used to detect an object touching a surface. Position of an object touching a surface can be determined using time-of-flight (TOF) bounding box techniques, or acoustic image reconstruction techniques, for example. Acoustic touch sensing can utilize transducers, such as piezoelectric transducers, to transmit ultrasonic waves along a surface and/or through the thickness of an electronic device. Location of the object can be determined, for example, based on the amount of time elapsing between the transmission of the wave and the detection of the reflected wave. An object in contact with the surface can interact with the transmitted wave causing attenuation, redirection and/or reflection of at least a portion of the transmitted wave. Portions of the transmitted wave energy after interaction with the object can be measured to determine the touch location of the object on the surface of the device.

A portable electronic device including: a plurality of sensors configured to generate, in response to a first contact with a body of a user in a vicinity of the portable electronic device, one or more first input signals; a microprocessor; and a memory having stored thereon instructions that, when executed by the microprocessor, control the microprocessor to execute, in response to an analysis of the one or more first input signals indicating that the first contact corresponds to a first gesture, and by the microprocessor, a first command corresponding to the first gesture.

Introduced is an electronic device comprising: a housing forming an outer appearance of the electronic device; an inductor disposed in the housing; a weight body coupled to the inductor and disposed to have a position that changes inside the electronic device according to the movement of the electronic device; a first conductor disposed on a first location of the housing; and a second conductor disposed on a second location of the housing, wherein the electronic device is configured such that a signal of a resonant frequency on the basis of locations of the first conductor, the second conductor, and the weight body is emitted, in response to a signal obtained from an external electronic device. Other various embodiments are possible.

An ultrasonic touch sensing system that uses both compressional and shear waves for touch and water detection is disclosed. When no touch or water is present, less shear and compressional wave energy is absorbed, so both shear and compressional wave reflections do not have significant amplitude decreases. When a finger is in contact with the sensing plate, both shear and compressional wave energy is absorbed, so both shear and compressional wave reflections have significant amplitude decreases. When water is in contact with the sensing plate, compressional energy is absorbed but little or no shear wave energy is absorbed, so while compressional wave reflections have significant amplitude decreases, shear wave reflections do not. From these amplitudes, a determination can be made as to whether no touch is present on the sensing plate, whether a touch is present on the sensing plate, or whether water is present on the sensing plate.

Content is projected onto on the surface of water such that it can be viewed from either above or below the surface. Using distortion mapping, depth sensing, and de-noising, the image can remain unaffected by ripples and allow the user to interact within the body of liquid and/or use it as input. Liquids of different density can be layered on the surface to create different refraction planes. Water currents and jets can be used to actively reduce ripples from user interaction, as well as actively adding or removing liquid from the container to counteract displacement or create effect.

A touch pad pressure detection method and apparatus, a storage medium and a computer device, wherein the method comprises: by means of an elastic wave sensor arranged below a touch pad, detecting a pressing operation on a touch pad to obtain a voltage signal; and determining pressure on the basis of the voltage signal.

An apparatus may include an ultrasonic sensor system, a low-frequency vibration source and a control system. The ultrasonic sensor system may include an ultrasonic receiver and an ultrasonic transmitter configured for transmitting ultrasonic waves in a first frequency range (e.g., 1 MHz to 30 MHz). The low-frequency vibration source may be configured for generating low-frequency vibrations in a second frequency range (e.g., the range of 5 Hz to 2000 Hz). The control system may be configured for synchronizing the generation of the first low-frequency vibrations and the transmission of the first ultrasonic waves.

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. An audio volume is controlled based at least in part on the indicator identifying the force intensity of the touch input.
