A tactile presentation panel according to the present invention includes a tactile presentation voltage generation circuit that generates a voltage signal having a first frequency to be applied to at least one first electrode located in at least a partial region on an operation surface of the tactile presentation panel, and generates a voltage signal having a second frequency different from the first frequency to be applied to at least one second electrode located in at least a partial region on the operation surface of the tactile presentation panel, a charge discharge portion that is connected to the tactile electrode and discharges charges accumulated in a conductive elastic portion, and a touch detection circuit that detects contact of the user with a tactile presentation knob.

The present disclosure generally relates to navigating user interfaces using hand gestures.

A controller for an electronic system may include a linear hand strap adjuster to accommodate different hand sizes of users who may hold the controller in their hand. For example, a linear slot may be defined in the handle at a proximal end of the handle that is adjacent to the neck region where the handle is adjoined to the head. The linear slot may extend longitudinally along the handle. An anchor disposed within the linear slot may protrude from the outer surface of the handle to provide a point of attachment for an end of the hand strap. Accordingly, a first end of the hand strap is configured to be coupled to the anchor, and the anchor is movable along the linear slot to adjust the first end of the hand strap.

A pressure detection structure and an electronic device are provided that improve sensitivity and accuracy of pressure detection. The pressure detection structure includes: N piezo-resistors connected at the first dielectric layer to form a Wheatstone bridge, where an opening of a first cavity is provided on the first surface of the substrate. The two ends, in a first direction, of the vertical projection of a first piezo-resistor among the N piezo-resistors on a contact surface between the N piezo-resistors and the first dielectric layer are located respectively on the two sides, in the first direction, of the vertical projection of the first cavity on the contact surface. The long side of a second piezo-resistor among the N piezo-resistors is perpendicular to the first direction, and the vertical projection of the second piezo-resistor on the contact surface does not overlap with the vertical projection of the first cavity.

An image processing component includes: a display control configured to display a to-be-edited image on a first area in a display area or display a target image after performing an adjustment operation on the to-be-edited image; an image scale adjustment control configured to display, in response to a first control instruction, an image scale adjustment interface on an area in the display area other than the first area, and display a scale touch area and a first overlay function touch area in the image scale adjustment interface; and an image rotation control configured to display, in response to a second control instruction, an image rotation adjustment interface on an area in the display area other than the first area, and display a rotation touch area and a second overlay function touch area in the image rotation adjustment interface.

Aspects of the present disclosure relate to modular expansion systems for use in head-worn computing systems. In an head-worn computer, an electrical connector is adapted to electrically connect with a modular expansion module, wherein the modular expansion module adds a capability to the head-worn computer and is removeably mounted to the head-worn computer, and a mount is adapted to physically secure the modular expansion module to the head-worn computer.

A calibration method and a calibration apparatus for a knob applicable to a touch panel are provided. The knob includes at least one sensing pad. The calibration method includes: obtaining sensed position(s) of each sensing pad by sensing a position of the sensing pad through the touch panel; and calculating a position of a center of the knob by using a formula of a radius of a circumscribed circle according the sensed position(s) of each sensing pad.
