An electronic device may have input-output devices such as sensors, displays, wireless circuitry, and other electronic components mounted within a housing. The housing may have opposing front and rear walls. A display may be formed on a front side of the device and may be overlapped by a front housing wall such as a glass layer. Sensors and other components may be formed on a rear side of the device and may be overlapped by a rear housing wall. The rear housing wall may have a glass portion or other transparent structure through which projectors project images onto nearby surfaces and through which image sensors and other optical sensors receive light. The housing may be supported by a stand. An electrical component in the stand may interact with an electronic device on the stand. Wireless circuitry in an external item may wirelessly couple to wireless circuitry within the housing.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

Head worn computers may include two physically separated cameras mounted on a front surface that capture movements of a finger of the user of the head-worn computer. The head worn computer includes an image source adapted to display content in a see-through display of the head-worn computer, wherein the content is positioned to be perceived by a user as positioned on a surface proximate the head-worn computer. A processor of the head worn computer is adapted to develop a 3D model, based on the captured finger movements and the position of the content, describing an interaction of the finger with the content.

An input device with a projecting function is provided, including: a first input device and a second input device. The first input device has a first projection unit, and the second input device has a second projection unit. The first projection unit and the second projection unit are configured to execute 2D projection or 3D projection. When a projection direction of the first projection unit is the same as that of the second projection unit, the first projection unit and the second projection unit execute the 2D projection. When the projection direction of the first projection unit is perpendicular to that of the second projection unit, the first projection unit and the second projection unit execute the 3D projection. The present disclosure provides a relatively sharp 2D projected image and a function of simplifying a structure of an input device.

Systems, devices, and methods provide for the prevention of laser light escaping a foldable wearable heads-up display (WHUD) when the WHUD is folded. For a WHUD that adopts the form factor of conventional eyeglasses or sunglasses, enabling the WHUD to fold “like glasses” can cause an interruption in the optical path of display light and enable display light to escape into the external environment. This can be hazardous when laser light is used to provide display light. Systems, devices, and methods that automatically detect, sense, and/or respond to the fold configuration state of a WHUD are described. When the WHUD is unfolded a laser-based display operates normally. When the WHUD is folded the laser-based display is disabled to prevent laser light from projecting out of the WHUD through the folded region. Proximity sensors and laser light containing mechanisms also may be employed as alternative or supplementary safety elements.

An image display apparatus includes a display unit configured to display an observation image on a rectangular display area, an observation optical system configured to lead light from the display area to an exit pupil to present an observed image. The observation optical system has a distortion that leads a light flux from at least a first corner portion among four corner portions of the display area to the exit pupil so as to cause the light flux from the first corner portion to form the observed image that has a shape lacking its angled portion corresponding to the first corner portion. A display processor performs a non-display process that does not display the observation image in a second corner portion other than the first corner portion among the four corner portions of the display area.

A tilt platform for use in an HMD comprises a monolithic spring structure including a first outer planar structure, a second outer planar structure, a middle planar structure disposed between the first and second outer planar structures, a first hinge structure coupling the first outer planar structure and the middle planar structure to each other, and a second hinge structure coupling the second outer planar structure and the middle planar structure to each other. The first and second hinge structures have respective first and second hinge axes that are orthogonal to each other. The tilt platform further comprises a first adjustment mechanism configured for tilting the first outer planar structure and the middle planar structure relative to each other about the first hinge axis, and a second adjustment mechanism configured for tilting the second outer planar structure and the middle planar structure relative to each other about the second hinge axis.

An electronic system includes: a raise objects module configured to raise a first object along a Z-axis displaying the first object above a display; a height determination module, coupled to the raise objects module, configured to generate a first adjustment value based on a height determining factor including frequency; and an adjustment module, coupled to the height determination module, configured to adjust the first object along the Z-axis based on the first adjustment value.

A projection method and an electronic device are provided. The method includes: projecting a first projection content from a first projection unit; determining at least one second projection unit of the electronic device in the presence of a first operation; and projecting the first projection content from the at least one second projection unit.

In an example implementation according to aspects of the present disclosure, a method may include receiving, on a touch sensitive mat of a computing system, a touch input associated with a first event type. The method further includes determining whether to transform the touch input associated with the first event type to a different event type, and sending, to an application, the touch input associated with an event type based according to the determination.
