Aspects of the present invention relate to methods and systems for imaging, recognizing, and tracking of a user's eye that is wearing a HWC. Aspects further relate to the processing of images reflected from the user's eye and controlling displayed content in accordance therewith.

Provided herein are an auxiliary device and a navigation system using the auxiliary device. The auxiliary device is configured to integrate with a pen mouse. When the pen mouse is tightly combined with the auxiliary device, the auxiliary device determines to use a first cursor displacement information data provided by the pen mouse and/or a second cursor displacement information data provided by the auxiliary device as a control signal for controlling a cursor corresponding to an electronic device according to an operation mode selected by the user.

An optical film includes a substrate, an absorption pattern and a scattering reflection layer. The substrate has a contact surface and a back surface opposite the contact surface, wherein the substrate allows a first light to pass and is made of a non-rigid material. The absorption pattern is arranged on the contact surface of the substrate to absorb the first light. The scattering reflection layer is arranged on the back surface of the substrate to scatter and reflect the first light to the contact surface of the substrate. The foregoing optical film enables an optical reader device to detect variations of the reflected first light, which is caused by deformation of the substrate, so that the corresponding force information can be obtained. A user input system including the foregoing optical film is also disclosed.

Aspects of the present disclosure relate to visual presentation techniques for micro-Doppler signatures. A method may include receiving a micro Doppler signature indicative of a projectile flight path, identifying a beginning trace marker and a termination trace marker, and presenting in a head-worn computing system field of view digital content representative of the projectile flight path, wherein the beginning trace marker and termination trace marker provide a world-lock perspective for a wearer of the head-worn computing system such that the digital content appears to remain referenced to the environment independent of a position of the head-worn computing system.

A method relates to the field of multimedia technologies, and in particular, to a remote control method and apparatus, which are used to implement remote control on a terminal, includes obtaining a presentation image, where the presentation image is an image used to present an operation performed on a terminal, detecting a presentation screen picture in the presentation image according to detection parameter information of the terminal, where the presentation screen picture is a screen picture of the terminal in the presentation image, determining a mapping relationship between a pixel on the presentation screen picture and a pixel on a display screen of the terminal according to parameter information of the presentation screen picture and screen parameter information of the terminal, and controlling the terminal according to information about an operation by a user on the presentation screen picture, and the mapping relationship.

An optical member includes: a substrate; and a dot that is in contact with a surface of the substrate, in which the dot is formed of a liquid crystal material having a cholesteric structure, the substrate includes a liquid crystal layer that is formed on the surface in contact with the dot, and the liquid crystal layer is a layer in which orientation of a liquid crystal compound is immobilized. The optical member includes a dot in a shape having a large maximum height with respect to a diameter, the dot being formed of a liquid crystal material having a cholesteric structure in which orientation disorder is reduced. As a result, the detection sensitivity of the dot pattern in various directions including an oblique direction is high. By using the optical member according to the present invention, an image display device having a high data input sensitivity can be provided.

A sound controlled light pen includes a main body and a sound controlled light emitting structure. The main body includes a pen barrel and a cartridge installed in the pen barrel. The sound controlled light emitting structure is connected to the pen barrel and includes a casing with a transparent portion, a transparent film covered onto the transparent portion, a microphone, a light emitting element, and a controller. The casing A further contains a circuit board provided for installing and electrically connecting the microphone that senses a change of sound and generates a sense signal, the light emitting element that is configured to be corresponsive to the transparent portion, and the controller that controls the light emitting element to emit light after receiving the controller sense signal, so that the sound controlled light pen and the sound controlled light emitting structure have excellent interactions with each other.

An optical touch pen includes a pen case, an operation module, and a power module. The operation module is disposed within an upper cover of the pen case, and includes a pen tip, a supporting part, a circuit board and a multi-directional auxiliary element. The multi-directional auxiliary element is arranged between an inner wall of the upper cover and the engaging structure of the supporting part. The power module is disposed within a lower cover of the pen case. When an external force is applied to the pen tip, the pen tip and the supporting part are shifted in response to the external force, the engaging structure of the supporting part is shifted relative to the multi-directional auxiliary element, and the external force is transmitted downwardly to the circuit board. Consequently, a current switch on the circuit board is triggered and the power module is electrically conducted.

Techniques are disclosed that can be implemented as a system configured for image matching-based pointing and/or selection from information presented in an image displayed by a projection device. A pointing device configured as described herein may be pointed at a target portion of an image displayed by a projection device and allowed to capture an image inclusive of that target portion. In turn, the captured image data may be compared with data pertaining to the original displayed image. The resultant pointing location data can be used to generate one or more pointing indicators within the original image, and the projection device may display the resultant annotated image on screen, in some cases in real time and/or with precision resolution of a single pixel. A subsequent user selection can be made based on the known location of the pointing indicator. The techniques provide for more native human-machine interaction than existing approaches.

An input device includes: a sensor; a detection circuit which, in operation, detects a first indicated position indicated by an electronic pen in a two-dimensional space in accordance with transfer of a signal between the electronic pen and the sensor; one or more processors; and one or more memory devices storing instructions that, when executed by the one or more processors, cause the one or more processors to: detect a second indicated position indicated by the electronic pen in a three-dimensional space, and generate position information of the electronic pen in the two-dimensional space or the three-dimensional space based on the second indicated position and first indicated position. The input device enables a position indicated by the electronic pen and a pen posture of the electronic pen in the three-dimensional space to be detected in a satisfactory manner in view of precision and response speed.
