A wearable device and a control method are provided. The wearable device includes: a rotary disk, a housing, a position detecting unit, and a processor. The rotary disk is rotatably connected to the housing. The position detecting unit is disposed between the rotary disk and the housing. The position detecting unit is electrically connected to the processor. The position detecting unit is configured to detect a target position to which the rotary disk is rotated along the housing and to send the target position to the processor. The processor is configured to enable a shortcut function corresponding to the target position. Multiple positions on the housing correspond to multiple shortcut functions. The target position is one of the multiple positions.

A housing of an example of an electronic apparatus has a top surface and a bottom surface and has a flat shape. A power supply section having a flat shape is a power supply section, which is a housing case capable of accommodating a battery or is a battery, and the power supply section is provided at a position inside the housing that intersects with a reference plane perpendicular to the up-down direction. A first substrate is provided parallel to the reference plane on the top surface side relative to the power supply section. A second substrate is provided parallel to the reference plane on the bottom surface side relative to the power supply section. The electronic apparatus includes at least one of a vibrator and a speaker at a position that intersects with the reference plane.

Electromechanical polymer (EMP) actuators are used to create haptic effects on a user interface deface, such as a keyboard. The keys of the keyboard may be embossed in a top layer to provide better key definition and to house the EMP actuator. Specifically, an EMP actuator is housed inside an embossed graphic layer that covers a key of the keyboard. Such a keyboard has a significant user interface value. For example, the embossed key provides the tactile effect of the presence of a key with edges, while allowing for the localized control of haptic vibrations. For such applications, an EMP transducer provides high strains, vibrations or both under control of an electric field. Furthermore, the EMP transducer can generate strong vibrations. When the frequency of the vibrations falls within the acoustic range, the EMP transducer can generate audible sound, thereby functioning as an audio speaker.

A piezo haptic keyboard and touchpad user identification system may comprise a processor receiving an authenticating user input identifying an authorized user of the information handling system, and a controller operably connected to a plurality of piezo electric elements situated beneath the keyboard. The controller may detect haptic hardware typing or touch behavior parameters describing characteristics of a plurality of deformations of the piezo electric elements during interaction between the authorized user and the keyboard, and the processor may use machine learning to identify a repeated pattern of values for a combination of the haptic hardware typing or touch behavior parameters reoccurring during interaction between the authorized user and keyboard. The processor may associate the repeated pattern of values for the combination of the haptic hardware typing or touch behavior parameters with the authorized user for later, passive authentication of a user based on typing dynamics.

A dynamic texture device coupled to an information handling system input/output device adjusts texture at the input/output device surface based upon texture information generated at the information handling system, such as a walking surface in a virtual world defined by a gaming application. Texture at an elastic cover is adjusted by applying variable magnetic fields to a magnetorheological fluid (MRF) disposed under the elastic cover in a reservoir. For example, an electromagnet changes pole orientation and magnetic strength at MRF contained in a reservoir under a keyboard palm rest to simulate walking in a virtual world on different types of surfaces.

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.

This application discloses a wireless keyboard. The wireless keyboard includes a connection portion. The connection portion includes an accommodating cavity with an opening at an end and used for accommodating an electronic stylus. A wireless charging coil is arranged in the accommodating cavity. A charging interface and a wireless charging control module are arranged in the wireless keyboard. The wireless charging control module is connected to the charging interface and the wireless charging coil. The charging interface can receive a direct current signal. The wireless charging control module can convert, if it is detected that a direct current signal is inputted to the charging interface, the direct current signal into an alternating current signal and transmit the alternating current signal to the wireless charging coil. The wireless charging coil generates an alternating electromagnetic field in response to the alternating current signal, to wirelessly charge the electronic stylus.

An accessory device with a cover and keyboard section is described. The keyboard section includes a keyboard and a touchpad, while the cover section includes multiple segments. The cover section orients the electronic device such that a user can access the electronic device, the keyboard, and the touchpad. The cover section is rotationally coupled to the keyboard section by one or more hinge assemblies (including clutches and springs), allowing the cover section and the electronic device to rotate relative to the keyboard section. The cover section includes a first and second segment rotationally coupled together. To further adjust the electronic device, the first segment remains coupled to the electronic device, allowing the first segment and the electronic device to rotate relative to the second segment. The cover section can then suspend the electronic device over the keyboard section, and the electronic device does not contact the keyboard section.

One variation of a keyboard system includes: a substrate including an array of inductors; a tactile layer arranged over the substrate defining an array of key locations over the array of inductors; an array of magnetic elements, each arranged within the tactile layer at a key location configured to inductively couple to an adjacent inductor and configured to move relative to the adjacent inductor responsive to application of a force on the tactile layer at the key location; and a controller configured to read electrical values from the inductors. In response to detecting a change in electrical value at a first inductor, the controller also configured to: register a first keystroke of a first key type associated with a first key location defined over the first inductor; and drive an oscillating voltage across the first inductor to oscillate the tactile layer over the substrate during a haptic feedback cycle.
