Supplementing the movement stroke of a trackpad with a haptic response is one way to restore some or all of a reduced trackpad feel and overall performance caused by a reduction in the movement stroke. However, incorporating haptic responses in a clickable trackpad may interfere with accurate force measurement using physical movement of the trackpad as a proxy. The following describes haptic trackpads with anisotropic compliant spacers. The disclosed haptic trackpads permit selective haptic responses to a user, while also permitting accurate force measurement using displacement of a sensing surface caused by the user's finger(s) as a proxy.

An integrated computational interface device includes a housing, at least one image sensor, and a foldable protective cover. The housing has a key region and a non-key region, and a keyboard associated with the key region. The foldable protective cover incorporates the at least one image sensor. The protective cover is configured to be manipulated into a plurality of folding configurations, including a first folding configuration, wherein the protective cover is configured to encase the key region and at least a portion of the non-key region, and a second folding configuration, wherein the protective cover is configured to stand in a manner that causes an optical axis of the at least one image sensor to generally face a user of the integrated computational interface device while the user types on the keyboard.

A backlight module includes a flexible circuit board and a light guide plate. A first light source assembly, a second light source assembly, and a positioning member are disposed on the flexible circuit board. The light guide plate is disposed over the flexible circuit board and includes a first single key light guide area, a second single key light guide area, and a connection area. The first single key light guide area has a first through hole accommodating the first light source assembly. The second single key light guide area has a second through hole accommodating the second light source assembly. The connection area is located between the first and second single key light guide areas and has an accommodating hole. The flexible circuit board is overlapped with the light guide plate with the positioning member being accommodated in the accommodating hole.

A portable electronic device having a rollable display structure is proposed. When the rollable display panel is unrolled from the display drum inside the housing and drawn out of the housing, a self-standing guide unit guides the rollable display panel to be curved in an arc shape so that the rollable display panel stands upright on its own, whereby the rollable display panel may be maintained in an unrolled state without an additional structure. In this way, the size and weight of a product may be reduced, so that portability of the portable electronic device may be improved.

The disclosure provides a keyboard apparatus, which includes a printed circuit board (PCB), a keyboard module, and a display film. The PCB includes at least one lower pixel electrode disposed on the PCB. The keyboard module includes a transparent substrate, at least one upper pixel electrode, and multiple key mechanisms. The upper pixel electrode and the key mechanisms are disposed on the transparent substrate. The display film is disposed between the PCB and the keyboard module. The display film is adapted to be driven by the upper pixel electrode and the lower pixel electrode to display at least one image, where the image is suitable for presentation through any one of the key mechanisms. The display film includes a bistable display material or an electronic paper material. A first display substrate and a second display substrate of the display film are different from the PCB and the transparent substrate.

A wireless input output apparatus is disclosed. The wireless input output apparatus includes a first housing mechanically coupled to the wireless input output apparatus panel. The first housing is configured to house a plurality of input keys. Each of the plurality of input keys corresponds to one of a character, a letter, a number, a function, and a command. The wireless input output apparatus also includes a second housing mechanically coupled adjacent to the first housing and over the wireless input output apparatus panel. The second housing is configured to house a capacitive touch screen display for rendering visual information. The wireless input output apparatus may be tethered to computer, phone, laptop, tablet, and the like without interrupting workflow when receiving calls, texts, “DMs”, emails and the like.

The present disclosure provides a keyboard, including: a keyboard body; at least one physical key disposed on the keyboard body; at least one virtual key projection device connected to the keyboard body and configured to present, by means of projection, an image of at least one virtual key in a projection area outside the keyboard body; and a click detection device configured to detect whether a finger clicks on the projection area and determine on which virtual key the finger clicks in response to that the finger clicks on the projection area.

A system and method for providing a touch control system are disclosed. In one aspect a touch screen interface on a mechanical keyboard is disclosed. A touch sensing area on a keyboard having mechanical key mechanisms also provides a touch sensing surface. Touch position on the keyboard is detected and used to control a user interface. Unique touch sensing systems are also disclosed.

In certain embodiments, an electronic input device includes a knob assembly defining an annular cavity and including a magnetically attractable armature. The electronic input device also includes a ratchet assembly disposed within the annular cavity and includes a ring magnet. The electronic input device includes a clutch mechanism that has a friction disc assembly, and an electromagnet configured to generate a magnetic field that shifts the friction disc assembly between a first position in which the friction disc assembly prevents rotation of the ratchet assembly and a second position in which the ratchet assembly is free to rotate with the knob assembly. The ring magnet of the ratchet assembly interacts with the magnetically attractable armature to generate a ratcheting feedback in response to rotation of the knob assembly when the friction disc assembly is in the first position.

According to an embodiment, a mousepad comprises a cover layer and an integrated keypad. The cover layer has a lateral extension and an upper surface which is usable for placement (placing, putting down) of a computer mouse. The keypad covers a part of said lateral extension. In an area not covered by the keypad there is a mouse parking area. The mousepad comprises a mouse detector associated with the mouse parking area and a corresponding control unit. The control unit is configured such that the keyboard gets activated when the mouse is inside the mouse parking area and gets deactivated when the mouse is outside the mouse parking area.
