An electronic device is disclosed. The electronic device includes an inertial measurement element and a processor. The inertial measurement element is configured to obtain a first inertial measurement data when the electronic device moves. The processor is configured to perform the following operations: establishing a mixed reality environment coordinate system in correspondence according to the real space, and calculating a starting coordinate point of the electronic device in the mixed reality environment coordinate system; converting the first inertial measurement data into a first movement vector in the mixed reality environment coordinate system according to an inertial measurement data mapping model; calculating a first spatial operation point in the mixed reality environment coordinate system according to the starting coordinate point and the first movement vector in the mixed reality environment coordinate system; and executing a 3D scene editing program with the first spatial operation point.

An extended reality space generating apparatus and method are provided. The extended reality space generating apparatus generates a plurality of plane plates, a plate coordinate and a normal vector corresponding to each of the plane plates based on a plurality of point clouds, wherein the point clouds correspond to a real space. The extended reality space generating apparatus compares the plate coordinates and the normal vectors of the plane plates in a visual window to generate an effective plane plate set. The extended reality space generating apparatus generates an extended reality space corresponding to the real space based on the effective plane plate set.

A method for adjusting an optical switch keyboard and an optical switch keyboard using the adjusting method are provided. The optical switch keyboard has a number of key units. The method includes the following steps. A scan signal is applied to one of a number of scan lines by a control unit at a first scan time point. A light is emitted by a light source according to the scan signal. A light emitted by the light source is detected by a detecting element to generate a detecting electric signal. The detecting electric signal is read by the control unit to obtain a first read signal voltage. When the first read signal voltage is outside the voltage range of the pressed state of the key unit, the period of the scan signal is increased by a first predetermined amount by the control unit to obtain an adjusted scan signal.

A keyboard device includes M driving circuits DC()&#x2dc;DC(M), N transition circuits TC()&#x2dc;TC(N), a control module, M column signal lines C()&#x2dc;C(M), N row signal lines R()&#x2dc;R(N) and M*N key units KU()&#x2dc;KU(M,N). The control module performs a scanning process to sequentially scan the M column signal lines C()&#x2dc;C(M) in M scan cycles scan()&#x2dc;scan(M). If the key unit KU(k,x) connected with the k-th column signal line C(k) and the x-th row signal line R(x) is depressed, a scan voltage is transmitted from the k-th column signal line C(k) to the x-th row signal line R(x) through a switch sw(k,x) of the key unit KU(k,x). The transition circuit TC(x) connected with the x-th row signal line R(x) is turned on according to the scan voltage. Consequently, an output voltage Rout(x) from the transition circuit TC(x) has a first voltage level.

A wireless mouse includes a base having a top surface defining a button region and a non-button region, and a top cover including a cover body that separably covers the top surface of the base. The cover body has an inner surface facing the non-button region of the top surface and an integrally formed groove defining member extending from the inner surface into a space disposed between the cover body and the top surface of the base. The groove defining member cooperates with the inner surface of the cover body to define a positioning groove that is open to the space between the cover body and the top surface of the base into which a wireless receiver is received and releasably retained.

A light-emitting keyboard includes a keycap, a frame and a solid-state lighting source. The keycap has a light-entrance portion formed on the periphery thereof, and a touch surface for pressing by user. The keycap is made of light-guiding material and defines a light-guiding path from the light entrance portion to the touch surface. The frame is arranged adjacent to the keycap and surrounds the periphery of the keycap. The frame is made of light-guiding material and forms at least one light-outputting surface. The at least one light-outputting surface is contiguous to the light-entrance portion. The solid-state lighting source is fixed to the frame and emits light from the light-outputting surface into the light-entrance portion by the light-guiding path, and exits from the touch surface of the keycap. The instant disclosure also provides an illuminating structure of the keyboard, and a keycap thereof.

A wireless mouse includes a base, a battery fastener and a top cover. The base has a top portion that is formed with a battery container unit. The battery fastener includes a fastener body connected removably with the top portion of the base. The battery fastener further includes a blockade unit extending from the fastener body and disposed directly above the battery container unit so as to prohibit the battery unit from exiting the battery container unit. The top cover is connected removably with the base for covering the battery container unit. When the top cover is connected with the base, the battery fastener is located between the top portion of the base and the top cover.

The instant disclosure is a resilient pressing member structure having a pressing unit disposed on top of a translucent insulated layer, an upper cover, a light-emitting unit, two conductive layers and a spacer. The pressing unit includes a plurality of pressing members while the cover is formed with a cavity filled with a fluid to achieve the effect of pressure dispersion. A light guiding structure and a light reflecting structure are disposed on the topside and the backside of the insulated layer, respectively. The insulated layer is formed by at least one light unit opening which extends through the insulated layer. The light-emitting unit is hosted inside the light unit opening. Light from the light-emitting unit penetrates the insulated layer and reaches the pressing member. Then the guiding structure directs light while the reflecting structure reflects light towards the pressing member, thus illuminates the pressing member.

A wireless mouse comprising an operating interface, a wireless communication module and a control unit is provided. The wireless communication module is for communicating with a receiver electrically coupled to a computer. When the operating interface is continuously pressed for a first particular period of time, the control unit controls the wireless mouse to enter a power-saving mode. When the operating interface is continuously pressed for a second particular period of time, the control unit recognizes the identity of the wireless mouse via the wireless communication module and the receiver.
