The invention provides systems, devices and methods for improved guidance or assistance of data input into a touch screen enabled device such as a mobile phone, tablet, payment terminal etc. The invention is particularly beneficial for use in situations where visual observation of the screen is impaired or not possible, either because of a user's disability or environmental factors. One aspect the disclosure provides a data input assistance device comprising: a body for placement adjacent to a touch screen of an electronic device; at least one input zone provided in the body and arranged to facilitate a user to operate an area of the touch screen via contact with a surface of the screen; and at least one location indicator arranged to communicate, to a software component associated with the electronic device, the location of the input assistance device relative to the touch screen. The invention enables the provision of a virtual input arrangement such as a virtual pinpad, keyboard or keypad, at a location specified by a user. It also enables movement of the virtual input arrangement during use.

An electronic pen cartridge is replaceable with a refill of a stationery ballpoint pen such that the stationery ballpoint pen housing can be reused as the electronic pen housing. The electronic pen cartridge is of a capacitance type and includes a pen tip which is projectable from an opening on one side in an axial direction of the pen housing. Inside the tubular cartridge housing are an electronic circuit including a signal transmission circuit configured to generate a signal to be supplied to a position detection sensor, and a rechargeable power storage device configured to supply a power supply voltage to the electronic circuit. A coil is wound around a rear end portion of the cartridge housing on a side of the cartridge housing opposite from the pen tip side. The power storage device is charged by a current induced in the coil based on an externally supplied magnetic field.

Disclosed is a wireless charging mouse, comprising a wireless power receiving circuit, a wireless radiating circuit, a displacement detecting circuit and a control circuit. The control circuit is electrically connected to the wireless power receiving circuit, the wireless radiating circuit and the displacement detecting circuit. The wireless power receiving circuit wirelessly receives electromagnetic energy from a charging board. The displacement detecting circuit detects the displacement of the wireless charging mouse. The control circuit receives the electromagnetic energy from the wireless power receiving circuit, and outputs a displacement detecting signal to a wireless receiver through the wireless radiating circuit according to the detected displacement obtained from the displacement detecting circuit. When the electromagnetic energy received by the wireless charging mouse is less than a predetermined electromagnetic energy, the control circuit stops outputting the displacement detecting signal to the wireless receiver.

A key structure includes, from top to bottom in sequence: at least one key main body, made of light transmissible material; a key frame, adapted to mount the key main body; an elastic supporting portion, allowing the key main bodies to move back and forth vertically; at least one bump, formed on one side of the elastic supporting portion; a detection module, sensing the action of the key main body and allowing the bump to be in touch therewith selectively; and a display screen, configured on one side of the detection module. A user can see the bottom display screen through the key main body directly, and the elastic supporting portion drives the bumps to move downward to touch the detection module after the user presses the key main body down. Whereby, the applicable range of the present invention is increased by changing the contents of the display screen.

Examples are disclosed that relate to the use of a microstructured adhesive tape for attaching an accessory device onto a computing device. One example provides a system, comprising a computing device, and an accessory device mountable to the computing device via a microstructured adhesive tape on one of the computing device and the accessory device, the microstructured adhesive tape configured to adhere to a mating surface on another of the computing device and the accessory device.

A charging board with an adjustable charging position and a charging method thereof are provided. The charging board includes a control circuit, an indicating circuit and a board body. The board body has a coil accommodating portion, and the coil accommodating portion has a transmitting coil. The transmitting coil can be adjusted in the coil accommodating portion. The control circuit detects the storage position of the transmitting coil, and controls the indicating circuit to output a corresponding indication signal according to the detection result. Thereby, the charging board can be used by a user to adjust the charging position.

An automatic method of setting a desktop background is provided. The automatic method of setting a desktop background is applied to an electronic device which is combined with a protective cover, wherein the protective cover has a conducting area corresponding to a specific shape, location or area. The method includes the following steps of receiving protective cover information generated by a touch screen of the electronic device touching the conducting area of the protective cover; determining whether the protective cover information is in accordance with one of a plurality of preset protective cover information; and setting desktop background displayed by the touch screen according the preset protective cover information when the protective cover information is in accordance with one of the plurality of preset protective cover information.

The invention relates to an input device comprising capacitive detection device having detection surface including first array of array electrodes; electronic evaluation unit electrically connected to array electrodes to form associated electric measuring field array for spatially resolving detection of capacitive influence on detection surface; handling means disposed on detection surface to be movable along an adjustment path parallel to detection surface, in order to perform an operating input; position indicator; and coupling device with a first surface on which a second array of coupling electrodes is formed, and with a second surface on which a third array including spaced-apart contact surfaces is formed. Based on the position of the handling means, contact surfaces are touch-contacted by the position indicator. The coupling device includes several electrically conductive connections to capacitively influence the measuring field array. The electronic evaluation unit is configured to detect position-dependent influence on measuring field array.

Various examples are provided for adapters for virtual reality (VR) hand controllers. The adapters can be coupled to hold the VR controllers in temporal axial alignment. In one example, an adapter includes a first end, a second end and one or more cross members connecting the first and second ends. The first adapter coupled to the second adapter in a fixed temporal orientation via a first coupling assembly installed in the first end or the second end of the first adapter and a second coupling assembly installed in the first end or the second end of the second adapter. For example, the first and second coupling assemblies can include a post coupling assembly and a recess coupling assembly. In another example, a system including two adapters can be coupled together to hold VR hand controllers in a fixed orientation with each other, e.g., in temporal axial alignment.
