An indicator detection method includes operating in a first mode and operating in a second mode. The first mode includes detecting a position of a first indicator on a operation surface by detecting first light emitted by the first indicator, emitting second light by a light emitting device, and detecting a position of a second indicator on the operation surface by detecting reflected light of the second light reflected by the second indicator. The second mode includes reducing a light amount of the second light when it is determined that the first indicator is in contact with the operation surface, and detecting the position of the first indicator on the operation surface by detecting the first light in a state where the light amount of the second light is reduced.

A manipulating device includes an analog manipulator tiltable or slidable in a first direction perpendicular to a central line along a second direction, and a plurality of manipulating buttons disposed in surrounding relation to the analog manipulator. The manipulating buttons include a first manipulating button positioned off the central line in the first direction. The analog manipulator is tilted or slid in the first direction, a position of an upper end of the first manipulating button along the second direction is higher than a position of an outer edge of the analog manipulator which is closer to the first manipulating button, along the second direction.

A wearable device includes a device housing configured to be worn on a first surface of a user, a set of one or more SMI sensors, and a processor. The set of one or more SMI sensors is mounted within the device housing and configured to emit a set of one or more beams of electromagnetic radiation, with each beam emitted in a different direction extending away from the first surface. The set of one or more SMI sensors is also configured to generate a set of one or more SMI signals containing information about a relationship between the device housing and a second surface. The processor is configured to extract the relationship between the device housing and the second surface from digitized samples of the set of one or more SMI signals.

A modular holding fixture for selectively coupling to a wireless hand-held inertial controller to provide passive optical and inertial tracking in a slim form-factor for use with a head mounted display that operates with six degrees of freedom by fusing (i) data related to the position of the controller derived from a forward-facing depth camera located in the head mounted display with (ii) data relating to the orientation of the controller derived from an inertial measurement unit located in the controller

An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes multiple emitters and detectors coupled with an optical coupler assembly through a waveguide on the surface on the optical-touch sensitive device. Each emitter produces optical beams which propagate in the waveguide via total internal reflection and are received by the detectors. Touch events disturb the optical beams, and are determined based on the disturbances. The waveguide has at least one dead zone on its surface. The dead zone is formed with a cover layer having a top surface and a bottom surface where the bottom surface of the cover layer is directly coupled to the top surface of the waveguide. The cover layer preserves optical beam propagation in the waveguide and makes the dead zone insensitive to touches on the top surface of the cover layer.

A computing system for direct three-dimensional pointing includes at least one computing device, and a pointing/input device including at least one light source and a motion sensor module for determining absolute and relative displacement of the pointing/input device. At least one imaging device is configured for capturing a plurality of image frames each including a view of the light source as the pointing/input device is held and/or moved in a three-dimensional space. Two or more imaging devices may be provided. A computer program product calculates at least a position and/or a motion of the light source in three-dimensional space from the plurality of sequential image frames and from the pointing/input device absolute and relative displacement information, and renders on the graphical user interface a visual indicator corresponding to the calculated position and/or the motion of the light source. Methods for direct three-dimensional pointing and command input are described also.

At a first time point, a first light capturing device at a first spatial location in a three-dimensional (3D) space captures first light rays from light sources located at designated spatial locations on a viewer device in the 3D space. At the first time point, a second light capturing device at a second spatial location in the 3D space captures second light rays from the light sources located at the designated spatial locations on the viewer device in the 3D space. Based on the first light rays captured by the first light capturing device and the second light rays captured by the second light capturing device, at least one of a spatial position and a spatial direction, at the first time point, of the viewer device is determined.

The present seam visually suppresses a gap defined between two adjacent reflective surfaces. The seam comprises a strip of light propagating material and a plurality of lighting units. The strip of light propagating material defines a front surface, two side surfaces and a back surface. The side surfaces of the strip of light propagating material is adapted for being positioning in the gap defined between the adjacent reflective surfaces. The lighting units are positioned along the back surface of the strip of light propagating material and are adapted for propagating light in the strip of light propagating material. When light is propagated in the strip of light propagating material, the gap between the two adjacent reflective surfaces is visually suppressed.

The disclosure comprises a stylus and a touch control system. The stylus comprises a pen body, a pen tip, and a light emitting device. The light emitting device is provided at the pen tip. A non-contacting end of the pen tip is connected to a bottom end of the pen body. The pen body is provided with a control module inside the pen body. The control module is electrically connected to the light emitting device and controls the light emitting device to emit light when a contacting end of the pen tip is applied to a reflective display.

A sensing module, and a Graphical User Interface (GUI) control apparatus and method are provided. The sensing module may be inserted into an input device, for example a keyboard, a mouse, a remote controller, and the like, and may sense a hovering movement of a hand of a user within a sensing area, and thus it is possible to provide an interface to control a wider variety of GUIs, and possible to prevent a display from being covered.
