Optical Steering of Component Wavelengths of a Multi-Wavelength Beam to Enable Interactivity
Briefly, in accordance with one or more embodiments, an information handling system comprises a scanning system to scan one or more component wavelength beams into a combined multi-component beam in a first field of view, and a redirecting system to redirect one or more of the component wavelength beams into a second field of view. A first subset of the one or more component wavelength beams is projected in the first field of view and a second subset of the one or more component wavelength beams is projected in the second field of view. The first subset may project a visible image in the first field of view, and user is capable of providing an input to control the information handling system via interaction with the second subset in the second field of view.
PROJECTION OF INTERACTIVE ENVIRONMENT
An interactive environment image may be projected onto one or more surfaces, and interaction with the projected environment image may be detected within a three-dimensional space over the one or more surfaces. The interactive environment image may be a three dimensional image, or it may be two dimensional. An image is projected onto a surface to provide a visual representation of a virtual space including one or more of the virtual objects, which may be spatially positioned. User interaction with the projected visualized representation of the virtual space may be detected and, in response to user interaction, the projected visualized representation may be changed.

OPTICAL DISTANCE SENSING USING A TARGET SURFACE HAVING A NON-UNIFORM DESIGN OF REGIONS OF DIFFERENT REFLECTIVITY
An apparatus, e.g. a proximity sensor module (10), for optical distance sensing includes a target surface (25) having a non-uniform design including a high-reflectivity region and a low-reflectivity region for light of a particular wavelength. The position of the target surface (25) is displaceable within the apparatus. The apparatus includes a light source (12) operable to emit light at the particular wavelength toward the target surface (25), and a photodetector (14) operable to sense at least some of the light emitted by the light source and subsequently reflected by the target surface (25). A processor is operable to correlate an output from the photodetector (14) with a distance to the target surface (25). A wall (22) may separate the light source (12) and photodetector (14) from one another, which can help reduce internal optical crosstalk. The light source (12) and photodetector (14) are mounted and electrically coupled to a substrate (16) that, in turn, can be mounted and electrically coupled to a printed circuit board (PCB) (18) of a host device. The light source (12) and photodetector (14) are surrounded laterally by a spacer or housing wall (20). The target surface (25) may be the backside of a touch interactive display screen (24) in the host device, e.g., a portable computing device such as a smartphone, tablet, wearable device, personal digital assistant (PDA), or personal computer. Circuitry (28) can be implemented, for example, as an integrated circuit chip or other processor and may include software and/or a look-up table stored in memory that allows the circuitry (28) to correlate the measured photodetector signal to a distance. When pressure is provided on the display screen (24) (e.g., by a person pressing her finger on the screen), the display screen is displaced slightly in the direction of the substrate (16) on which the light source (12) and photodetector (14) are mounted. As a result of the displacement, the intensity of light detected by the photodetector (24) changes. The signal measured by the photodetector (24) can be correlated to a distance value. If the distance value is within a specified range (or changes by at least a specified amount), for example, it can trigger some further action in the host device.

The image processing unit (24) includes a sensitivity setting unit that sets a first sensitivity for coarsely moving the index by the swipe operation or a second sensitivity for finely moving the index by detecting a contact operation to the touch panel in the swipe operation, and a movement control unit that moves the index on the basis of the swipe operation on the touch panel and the sensitivity set by the sensitivity setting unit.

In an embodiment, a touch sensitive device includes a touch interface having rows and columns and a signal generator for generating unique orthogonal signals on a plurality of the rows, respectively. A touch processor is identifies touch on the touch interface by processing touch signals present on the columns, and outputting a stream of touch events. A decimator receives the stream of touch events, selectively identifies one or more of the touch events in the stream and assembles information concerning one or more touch events in the stream, and outputs both the selectively identified touch events and the assembled information for use by the touch sensitive device.
