A Robotic control system has a wand, which emits multiple narrow beams of light, which fall on a light sensor array, or with a camera, a surface, defining the wand's changing position and attitude which a computer uses to direct relative motion of robotic tools or remote processes, such as those that are controlled by a mouse, but in three dimensions and motion compensation means and means for reducing latency.

A tracking method, for tracking an object based on a computer vision, includes following steps. A series of images is captured by a tracking camera. A first position of a trackable device is tracked within the images. An object is recognized around the first position in the images. In response to the object being recognized, a second position of the object is tracked in the images.

Devices and methods are disclosed for generating input. In one implementation, a stylus is provided for generating writing input. The stylus includes an elongated body having a distal end, and a light source configured to project coherent light on an opposing surface adjacent the distal end. The stylus further includes at least one sensor configured to measure first reflections of the coherent light from the opposing surface while the distal end moves in contact with the opposing surface, and to measure second reflections of the coherent light from the opposing surface while the distal end moves above the opposing surface and out of contact with the opposing surface. The stylus also includes at least one processor configured to receive input from the at least one sensor and to enable determining three dimensional positions of the distal end based on the first reflections and the second reflections.

An operating device includes a first light-emitting area provided on a front surface of the operating device, a first light-transmitting member that is formed with a material that transmits light and that makes up the first light-emitting area, a second light-emitting area provided on an upper surface of the operating device, a second light-transmitting member that is formed with a material that transmits light and that makes up the second light-emitting area, a light source, and a light guide member adapted to guide light of the light source to the first light-transmitting member and the second light-transmitting member. The light guide member includes a first guide section arranged behind the first light-transmitting member to guide light to the first light-transmitting member, and a second guide section that extends upward beyond a position of the first light-transmitting member toward the second light-transmitting member.

A housing of an example of an electronic apparatus has a top surface and a bottom surface and has a flat shape. A power supply section having a flat shape is a power supply section, which is a housing case capable of accommodating a battery or is a battery, and the power supply section is provided at a position inside the housing that intersects with a reference plane perpendicular to the up-down direction. A first substrate is provided parallel to the reference plane on the top surface side relative to the power supply section. A second substrate is provided parallel to the reference plane on the bottom surface side relative to the power supply section. The electronic apparatus includes at least one of a vibrator and a speaker at a position that intersects with the reference plane.

A gaze monitoring system comprising: an eye tracker comprising; a camera having an optical axis; a first IR source configured to illuminate a user's eyes; the first IR source located relatively near the optical axis of the camera; and at least one second IR source configured to illuminate the user's eyes, the at least one second IR source located relatively far from the camera's optical axis, in a position such that when the gaze angle is too large to get corneal reflection images of the first IR source, the image reflection of the at least one second IR source is visible by the camera, as a corneal reflection.

A wireless position tracking device, a display system, and a wearable device are provided. The wireless position tracking device includes a rigid body, point light sources, a motion sensor, and a wireless transmission module. The rigid body has an inner concave surface, a head, a connecting portion, and a tail. The connecting portion connects the head and tail. The point light sources are fixed to positions outside the inner concave surface. The motion sensor locates in the rigid body for sensing a motion thereof and generating motion information. The wireless transmission module locates in the rigid body and electrically connects the motion sensor for wirelessly transmitting the motion information to the head-mounted device. An image capturing module of the head-mounted device captures a pattern formed by the point light sources. The head-mounted device calculates a relative position of the wireless position tracking device according to the pattern and motion information.

A light emitting user input device can include a touch sensitive portion configured to accept user input (e.g., from a user's thumb) and a light emitting portion configured to output a light pattern. The light pattern can be used to assist the user in interacting with the user input device. Examples include emulating a multi-degree-of-freedom controller, indicating scrolling or swiping actions, indicating presence of objects nearby the device, indicating receipt of notifications, assisting pairing the user input device with another device, or assisting calibrating the user input device. The light emitting user input device can be used to provide user input to a wearable device, such as, e.g., a head mounted display device.

The present disclosure provides an optical tag-based information apparatus interaction method and system. The method includes: using a terminal device to perform image acquisition on an optical tag at a relative fixed position to an information apparatus so as to determine a position and an attitude of the terminal device relative to the optical tag; determining, in conjunction with a predetermined position of each information apparatus relative to the optical tag, the position of the terminal device relative to each information apparatus; acquiring an imaging position of each information apparatus on a display screen of the terminal device, and displaying an interactive interface of each information apparatus at the imaging position thereof on the display screen, such that an interactive operation can be performed on each information apparatus. The disclosure allows a user to control an information apparatus in a field of view anytime and anywhere, and interact with the device as What You See Is What You Get (WYSIWYG).
