The present disclosure relates to staggered arrays of individually addressable light-emitting elements for sweeping out angular ranges. One example device includes an astigmatic optical element. The device may also include an array of individually addressable light-emitting elements arranged to emit light towards the astigmatic optical element. The astigmatic optical element may be arranged to focus light emitted from each individually addressable light-emitting element to produce a substantially linear illumination pattern at a different corresponding scan angle within an angular range. The example device may further include a control system operable to sequentially activate the individually addressable light-emitting elements such that the substantially linear illumination pattern sweeps out the angular range. The individually addressable light-emitting elements may be staggered with respect to one another in the array such that the substantially linear illumination pattern sweeps out the angular range continuously.

The present disclosure relates to curved arrays of individually addressable light-emitting elements for sweeping out angular ranges. One example device includes a curved optical element. The device may also include a curved array of individually addressable light-emitting elements arranged to emit light towards the curved optical element. A curvature of the curved array is substantially concentric to at least a portion of the circumference of the curved optical element. The curved optical element is arranged to focus light emitted from each individually addressable light-emitting element to produce a substantially linear illumination pattern at a different corresponding scan angle within an angular range. The device may further include a control system operable to sequentially activate the individually addressable light-emitting elements such that the substantially linear illumination pattern sweeps out the angular range.

Methods for disambiguation and tracking of two or more wireless hand-held controllers with passive optical and inertial tracking within a system having a head mounted virtual or augmented reality display device having a forward facing optical sensor having a field of view, and wherein the display device interfaces with wireless hand-held inertial controllers for providing user input to the display device, with each controller two passive optically reflective markers, one marker being position at or adjacent each end of the controller and being separated by a known distance, and each controller also including an onboard inertial measurement unit for providing inertial data corresponding to its orientation.

Described is an apparatus for designing a pattern for a wearable item, comprising: (a.) position detector adapted to detect a position of at least a portion of a body of a user; and (b.) data processor adapted to compute at least one intersection of at least one virtual object and the portion of the body of the user, and pattern data representative of a pattern for the wearable item based on the intersection. In addition, described is a method for designing a pattern for a wearable item.

A position indicating device includes a housing in which an electronic pen including a pen tip is mountable, a force sense generator configured to generate a force sense, and a processor configured to control the force sense generator to generate the force sense when, with the electronic pen mounted in the housing, a distance between a position of the pen tip of the electronic pen in a virtual reality space and an object in the virtual reality space is equal to or less than a predetermined value.

Provided is a position detection method using a first imaging unit and a second imaging unit that each capture an image of an object. The detection method may include: acquiring a first captured image with use of the first imaging unit; acquiring a second captured image with use of the second imaging unit; defining a position vector of the object based on the first captured image; calculating a first direction vector directed from the second imaging unit to the object with use of the defined position vector; calculating a second direction vector directed from the second imaging unit to the object based on the second captured image; and calculating a position of the object based on the first direction vector and the second direction vector.

A camera integrates a magnet at one end of a housing to magnetically attract and attach the camera to a front side of a peripheral display, such as to support a video conference through an information handling system interfaced with the display. Camera position at a display panel front face is detected, such as with a touchscreen of the display panel or an infrared curtain presented from the camera dock along the display panel front face. Presentation of content at the display is adjusted based upon the camera position, such as to enhance a video conference by placing a window with an active speaker proximate the camera so that an end user of camera appears to be looking the speaker in the eye.

Systems and methods determine a swipe direction of an object on an electronic device to enable the performance of actions in response to the determined swipe direction. The swipe direction may be determined with respect to a biometric authentication sensor of the electronic device. According to certain aspects, signals that indicate the presence of an object may be received from proximity sensor(s) and/or a biometric authentication sensor. The swipe direction of the object may be determined based on the signals. An action may be performed on the electronic device in response to determining the swipe direction. An improved user experience of the electronic device may result through the use of these systems and methods.

In some embodiments, apparatuses and methods are provided herein useful for detecting traffic in a shopping facility. A system for detecting traffic in a shopping facility comprises: a plurality of light emitters coupled to motion sensors configured to emit light when motion is detected by the motion sensor; a light detector having a field of view including at least one of the plurality of light emitters; a database; and a control circuit configured to obtain data from the light detector relating to light emitted from the light emitters, estimate a location of the light emitted from the light emitters based on location data associated with the light emitter stored in the database, and track a path of a customer based on successive light emissions from the light emitters.
