Abstract: A method for displaying an on-screen keyboard is applied a computing device connected to a physical keyboard and a screen, where the physical keyboard includes a plurality of keycaps capable of responding to a touch on the keycap to output a first key signal and responding to a keystroke on the keycap to output a second key signal to the computing device, and the method for displaying an on-screen keyboard includes: displaying an on-screen keyboard on a topmost layer of a display image of the screen; reading the first key signal output by the physical keyboard corresponding to the touch on the keycap; and displaying, according to the first key signal, a first key mark at a position corresponding to the touched keycap on the on-screen keyboard.

Abstract: A display method of an on-screen keyboard, applied to a computing device connected to a physical keyboard, a screen and a sensor, the physical keyboard including a plurality of keys, and the sensor being configured to detect and obtain an operating position image, where the display method of the on-screen keyboard includes: displaying an on-screen keyboard at a topmost layer of a displayed image of the screen; reading the operating position image obtained by the sensor; converting the operating position image into an operating position data, where the operating position data includes relative position data of a key which is touched or is approached; and according to the operating position data, displaying a first key mark at a position corresponding to the key which is touched or is approached on the on-screen keyboard.

Abstract: A keyboard gesture instruction generating method includes: loading an instruction condition definition table, where the instruction condition definition table includes a plurality of gesture instructions, and each gesture instruction includes a plurality of instruction conditions, and each instruction condition has a corresponding defined value; reading an operating position image obtained by a sensor; converting the operating position image into an operating position data, where the operating position data includes relative position data of keys which are referenced; recognizing a gesture event according to multiple sets of the successive operating position data; obtaining a plurality of detected values of the gesture event and comparing the detected values with these defined values; if these detected values match with the defined values of all the instruction conditions of one of the gesture instructions, stopping tracking of the gesture event; and executing the matching gesture instruction.

Abstract: A keyboard device includes a base, a plurality of keys, a light source module, a first sensor, a second sensor, and a control module. An ambient luminance of the plurality of keys is detected by using the first sensor. When the ambient luminance is less than an ambient luminance at which the second sensor can capture a required image, the control module turns on the light source module to provide a light source for the plurality of keys to improve the ambient luminance, so that the second sensor to can clearly capture the required image and obtain the required data by means of analysis.

Abstract: A method for generating a touch control instruction, includes: loading an instruction condition definition table, where the instruction condition definition table includes a plurality of touch control instructions, and each touch control instruction includes a plurality of instruction conditions and definition values corresponding to the instruction conditions; reading a first key signal output by a physical keyboard corresponding to a touch on a keycap; recognizing a touch control event according to multiple consecutive first key signals; obtaining a plurality of detection values of the touch control event and comparing the detection values with the definition values; if the detection values match definition values of all instruction conditions of a touch control instruction, stopping tracing of the touch control event; and executing the matched touch control instruction.

Abstract: A manipulation apparatus includes a body, a connection cable, a connector, and a flexible conduit. The body includes a control element, buttons, and a directional control lever. The control element is in the body and is configured to receive a control signal generated by the buttons and the directional control lever. The buttons are at a first side of the body, and the directional control lever is at a second side of the body. The connection cable is connected to the control element. The connection cable includes a first end and a second end, and the first end is connected to a third side of the body. The connector is connected to the second end of the connection cable. A flexible conduit is outside the connection cable in a sleeve manner, where the flexible conduit extends from the first end of the connection cable to the second end.

Abstract: A keyboard set may be provided on chair armrests. The keyboard set includes a left keyboard, a right keyboard, a first detachable support, a second detachable support, and two multidirectional angle adjusting mechanisms. Each of the left keyboard and the right keyboard includes a plurality of keys. One end of the first detachable support is combined with the left keyboard, and one end of the second detachable support is combined with the right keyboard. The two multidirectional angle adjusting mechanisms are respectively provided between the first detachable support and the left keyboard, and between the second detachable support and the right keyboard.
