A keyboard dock can include a keyboard coupling; a front surface; and a front spacer that extends outwardly from the front surface, where the front spacer and the front surface form a mobile device support.

A portable electronic device includes a base, a first display pivotally connected to the base, a second display, and a linkage mechanism. The first display is movable to be opened or closed relative to the base. The second display is located between the base and the first display. The linkage mechanism includes at least one first link. Two ends of the first link are pivotally connected to the first display and the second display, respectively. When the first display is opened relative to the base, the at least one first link rotates to drive the second display to move up relative to the base. When the first display is closed relative to the base, the at least one first link rotates in an opposite direction to drive the second display to move down to be accommodated between the first display and the base.

An interface device includes an on-panel pad and a sensor controller. The interface device is used to perform an input to an electronic device in response to an operation by a user on a capacitive touch panel display of the electronic device. The on-panel pad causes sensor electrodes included in the touch panel display to generate a two-dimensional pattern of capacitance while the on-panel pad is on the touch panel display. When the two-dimensional pattern generated while the on-panel pad is on the touch panel display has been detected, the sensor controller generates or outputs data including operation information in response to a change in capacitance in a region that is associated with the two-dimensional pattern and that receives an operation of the on-panel pad, the operation information indicating an operation state of the on-panel pad.

Systems, methods, and non-transitory computer readable media for virtually extending a physical keyboard are disclosed. In one implementation, a non-transitory computer readable medium contains instructions that cause a processor to: receive image data representing a keyboard placed on a surface from an image sensor associated with a wearable extended reality appliance; determine that the keyboard is paired with the wearable extended reality appliance; receive an input for causing a display of a virtual controller with the keyboard; display, via the wearable extended reality appliance, the virtual controller in a first location on the surface, with original spatial orientation relative to the keyboard; detect a movement of the keyboard to a different location on the surface; and in response to the detected movement, present the virtual controller in a second location on the surface, with a subsequent spatial orientation relative to the keyboard that corresponds to the original spatial orientation.

Example implementations relate to computing devices with hinge bars, in some examples, a computing device may include a cover with a flexible hinge, a first housing, a first display device included in the first housing, a second housing, a second display device included in the second housing, and a hinge bar located between the first housing and the second housing, where the hinge bar includes an input/output port at an end of the hinge bar, and the hinge bar is electrically connected to the first display device via a first electrical pathway located in the cover and to the second display device via a second electrical pathway located between the second display device and the hinge bar.

An electronic device includes a first body; a second body having a first display device and capable of being physically connected to or separated from the first body, where if the second body is physically connected to the first body, the second body is rotatable relative to the first body; and a third body having a second display device and capable of being physically connected to or separated from the first body, where if the second body is physically connected to the first body, the second body is rotatable relative to the first body.

A computer system including an electronic device and an input device is disclosed. The electronic device includes a touch display area and a control unit. The input device includes a plurality of positioning structures and a grounding piece. The positioning structures are electrically connected to the grounding piece. When the input device is disposed on the touch display area of the electronic device, the control unit detects positions of the positioning structures on the touch display area, calculates a coverage area covered by the input device on the touch display area according to the positions, and determines a range of a display area of the touch display area according to the coverage area.

A cover device of an electronic device is provided. The cover device includes a cover housing configured to cover at least a portion of the electronic device in a first state in which the electronic device is electrically coupled to the cover device, and a bracket including a first surface on which a terminal part is disposed and a second surface which faces the cover housing, wherein the bracket includes at least one first magnet disposed adjacent to the first surface and at least one second magnet disposed adjacent to the second surface, the cover housing includes at least one third magnet, and the at least one third magnet is disposed to align with the at least one second magnet in a second state in which the electronic device is electrically isolated from the cover device.

A detachable electronic device is provided. The detachable electronic device is adapted to a cover with a plurality of folding sections. The detachable electronic device comprises: a body including a first surface and a second surface and a peripheral unit detachably connected to the body and including a pivot portion. The first connector is disposed at the first surface. The pivot portion includes a fixing pivot member and a magnetic pivot member pivotally connected to the fixing pivot member and including a second connector. When the first connector is magnetically attached to the second connector and the body is supported by folding the folding sections of the cover, the pivot portion is raised up by a distance from a support surface against which the peripheral unit abuts.

A plurality of modules are connected to the front side and back side of an electronic device via corresponding attachment/detachment units. The electronic device includes an orientation detection unit that detects the orientation of the electronic device. Based on a selection of a module to be removed and a touch operation on a touch panel of the electronic device, the selected module is determined to be either on the front side or the back side of the electronic device. When the electronic device is in an orientation suitable for removal of the selected module, the module is disconnected from the electronic device by a corresponding attachment/detachment unit.
