A reversed keyboard assembly is provided. The keyboard assembly includes a display unit, a touch screen placed on top of the display unit; and a top cover placed on top the touch screen, wherein top cover covers the touch screen and the display unit, wherein the top cover includes a plurality of transparent keys located in a predetermined distance above the touch screen for enabling a viewing of images displayed on the display unit.

An electronic device capable of adjusting light emitting frequency includes an oscillator used to generate an oscillation signal, a microcontroller connected to the oscillator, and a light emitting module connected to the microcontroller. The microcontroller is used to define that an oscillation times of the oscillator within a unit time period is an original oscillation times. The microcontroller sets a correspondence between a switching period and the original oscillation times. The microcontroller is further used to receive the oscillation signal to calculate a time elapse. The microcontroller is configured to control on or off of the light emitting module according to the switching period and the time elapse.

One embodiment provides a method, including: detecting, at a wireless charger integrated into an electronic device, a connection of a wearable accessory device, wherein the wireless charger is positioned proximate to a probable user contact position; and transmitting, using the wireless charger and during a period when the connection is established, a charge to the wearable accessory device; wherein the wearable accessory device is worn by a user during the connection. Other aspects are described and claimed.

A button assembly for an electronic device is disclosed. The button assembly integrates a biometric sensor below a top surface of the button. The button assembly is positioned relative to a secondary display of an electronic device. The secondary display can be positioned relative to a keyboard, such as above a top row of keys of the keyboard.

A keypad is provided in the present invention. The keypad includes a keypad shell and a keypad circuit board provided within the keypad shell. The keypad shell is provided with at least two subscriber identity module (SIM) card sockets and a first communication module connected to the SIM card sockets and configured to access the Internet. A SIM card switch is provided between the first communication module and the SIM card sockets. Compared to the prior art, the present invention enables, by means of providing the keypad with the at least two SIM card sockets and the first communication module supporting all major operators, the keypad to access the Internet when connected to a mobile terminal, and ensures uninterrupted Internet data access by switching to a SIM card of a different operator when the SIM card of the current operator has weak reception.

In an example in accordance with the present disclosure, an input movement tracking device is described. The input movement tracking device comprises a tracking device housing and a connector to mechanically attach the tracking device housing to an input device. The input movement tracking device also includes an electrical connector to receive input from the input device to be transmitted to a host computing device. A tracking system disposed within the tracking device housing tracks a position and orientation of the tracking device housing and the input device in physical space and a transceiver disposed within the tracking device housing communicates with the host computing device.

In example implementations, an electronic device includes a primary display, a secondary display, and a keyboard. The secondary display is coupled to the primary display. The keyboard is coupled to the secondary display and includes a first behavior key and a second behavior key. The first behavior key is to change a first display operation of the secondary display while the primary display is active. The second behavior key is to change a second display operation of the secondary display while the primary display is active.

A powered communication system comprises an improved layout of keys configured to treat, mitigate, or delay the onset and reduce the severity of symptoms of carpal tunnel syndrome (CTS) and other pathologies by reducing movement of a user's fingers during typing. A layout of the powered communication system comprises the most-used letters on a home or center row while retaining a plurality of keys in the same placement as the QWERTY keyboard. The powered communication system further comprises customizable function keys to further reduce finger movement and at least one sensor to monitor a user's health while typing.

An information handling system touchscreen display detects touches at a touch detection surface as inputs to the information handling system to report as inputs to an embedded controller. An embedded controller detects placement of a keyboard on the touchscreen display in a forward position and in response commands an infrared position detector to activate to detect finger movement at a virtual touchpad disposed external to the information handling system housing. A microphone disposed proximate the virtual touchpad detects end user taps as inputs and a projector disposed proximate the virtual touchpad illuminates a boundary of the virtual touchpad. When the keyboard is moved from the forward position to a rearward position, a virtual touchpad may be presented on the display and the infrared position detector may be deactivated.

A foldable computing device provides user interface (UI) transitions and optimizations while operating in a productivity mode. When the foldable computing device is operating in productivity mode, it can present a UI below a hardware keyboard placed over a display region and occluding only a top portion of the display region or a software keyboard presented in the display region occluding only the top portion of the display region. If the hardware keyboard or the software keyboard occlude only the bottom of the display region, a UI can be shown above the hardware keyboard or the software keyboard. The foldable computing device can adjust the position of UI windows that are occluded when the hardware or software keyboard is placed on the display region. The foldable computing device can move the UI windows back to their original positions if the hardware or software keyboard no longer occlude the display region.
