An optical touch sensor is disclosed which includes a plurality of light emitting bare dies attached directly to a first printed circuit board and placed at a first edge bordering an object surface, the plurality of light emitting bare dies being commonly encapsulated in a first encapsulation having a first reflective surface, and a plurality of light detecting bare dies attached directly to a second printed circuit board and placed at a second edge bordering the object surface across from the first edge, the plurality of light detecting bare dies being encapsulated commonly in a second encapsulation having a second reflective surface, wherein light emitted from the plurality of light emitting bare dies can be detected by the plurality of light detecting bare dies through reflections of the first and the second reflective surface, and wherein a light beam traveling from the first reflective surface to the second reflective surface is above and substantially parallel to the object surface.

An intelligent hybrid touch display device, including: a touch display unit; a rotary mechanical switch, being integrated with the touch display unit in a body; and a control unit, located in the body and including: a first interface for driving the touch display unit; a second interface coupled with the rotary mechanical switch; a touch and switch detection unit coupled with the first interface and the second interface; a transmission interface for communicating with at least one external device; and a processor and an operating system stored in a memory, the processor being coupled with the touch and switch detection unit and the transmission interface, and being used for executing a control program with a support of the operating system, so that the touch display unit and the rotary mechanical switch can cooperate to provide a hybrid operation for selecting, changing or activating function options.

A controller includes a touch sensor and a proximity sensor. Information on when and where a user touches the surface of the touch sensor is detected. Additionally, information on pre-touch events is detecting. The pre-touch events correspond to a user's finger hovering over the touch sensor within some maximum depth. A display device generates visualizations based on the hover events and the touch events. This can include providing visual feedback in a hover mode where a user's finger is, relative to the touch sensor. Additionally, various forms of navigation information may be provided in the hover mode, as well as other control information.

A system is provided that is capable of storing and presenting within an interface, interactive content. For instance, it is appreciated that there may be a need to effectively present interactive content at a customer site using standard computer equipment. Also it may be beneficial to provide user tools to easily calibrate the system and customize the interactive content to suit the particular interactive content and environment. A distributed system permits the use, customization and display of interactive content among a number of various site locations.

A flat touchscreen monitor that uses touchscreen-effectuating components from a cathode ray tube (CRT) monitor to allow users to upgrade to a flat touchscreen monitor without having to purchase a new flat touchscreen monitor. The flat touchscreen monitor includes first, second, third, and fourth curved-array connectors that were previously configured to electrically attach to a pair of curved-array of IR transmitters and a pair of curved-array of IR receivers, respectively. The monitor further includes first and second straight-array of IR transmitters electrically coupled to the first and second curved-array of connectors, respectively. Additionally, the monitor includes first and second straight-array of IR receivers electrically coupled to the third and fourth curved-array of connectors, respectively. The third and fourth curved-array of connectors are electrically coupled to a touchscreen controller. The straight-array of IR transmitters and receivers may be positioned on all sides of a flatscreen to effectuate the touchscreen operation.

A system and method for generating air plasma by radiating a laser in the air, and making a user feel a somatic sense such as a tactile sense, a thermal sense or the like using a principle of inducing a state change in a medium as a result of a shock wave or an electric field generated by the air plasma.

Influence of external light is suppressed. With a photodetector including a photodetector circuit which generates a data signal in accordance with illuminance of incident light and a light unit which overlaps with the photodetector circuit, a first data signal is generated by the photodetector circuit when the light unit is in an ON state, a second data signal is formed by the photodetector circuit when the light unit is in an OFF state, and the first data signal and the second data signal are compared, so that a difference data signal that is data of a difference between the two compared data signals is generated.

The touch driver circuit comprises a photosensor module, a data writing module, a driver module, and a control module. The data writing module transmits a scan signal at a scan signal terminal to the driver module under the control of the scan signal terminal. When the scan signal drives the driver module to turn on, the driver module outputs a touch sensing signal to the control module; the touch sensing signal decreases with the increase of an intensity of light irradiated on the photosensor module. Under the control of the control signal, the control module outputs the touch sensing signal output by the driver module to the touch signal sensing terminal, thereby realizing the touch sensing function.
