HMD Temple Touch Sensor for Visual and Audio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays face challenges in operability due to the difficulty in providing sufficient touch-sensitive space for controlling visual and auditory information, making it hard to select and control target information effectively.
Innovation Solution
A head-mounted display with a sensor unit on the temple that divides the touch-sensitive region into distinct areas for controlling visual and auditory information, allowing users to switch between them based on input location and maintaining control until the input is released, providing tactile feedback for confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a head mounted display is lightened and miniaturized to be worn like glasses, then the device becomes more wearable and portable, but the touch-sensitive space for controlling visual and auditory information becomes insufficient
Solution Approach 1:
The patent extends the touch-sensitive area from the limited front surface to the temple portion of the head mounted display, utilizing a different spatial dimension. The sensor unit is positioned on the temple to detect control inputs, effectively expanding the available control area without increasing the device's overall size or weight.
Solution Approach 2:
The temple portion of the head mounted display serves as an intermediary control interface. Instead of requiring direct interaction with a large front panel, the temple acts as a mediator that detects control inputs (such as touching or sliding gestures) and transmits them to control visual and auditory information, enabling operation with minimal front surface area.
2Volume of moving object
If the touch-sensitive space is reduced for miniaturization, then the device becomes more compact and wearable, but the operability for selecting and controlling target information deteriorates
Solution Approach 1:
The control interface is moved to the temple portion, utilizing a different spatial dimension than the traditional front surface. This allows the device to maintain a compact volume while providing sufficient control area on the temple for selecting and manipulating visual and auditory information.
Solution Approach 2:
The temple portion is divided into distinct regions: a first region adjacent to the display unit for controlling visual information, and a second region adjacent to the audio output unit for controlling auditory information. This segmentation allows users to intuitively select control targets based on which information type they wish to control, improving operability despite the compact size.
3Measurement precision
If control regions are divided into separate areas for visual and auditory information, then the precision of control target selection is improved, but the device complexity increases
Solution Approach 1:
The temple portion is segmented into a first region and a second region based on their proximity to different output units. The sensor unit detects which region is being touched and automatically determines the control target (visual or auditory information) based on this spatial information, providing precise control selection without requiring complex additional components.
Solution Approach 2:
The control system automatically determines the control target based on the location of the control input on the temple portion. The sensor unit and controller work together to self-determine whether the user intends to control visual or auditory information based solely on which region is touched, eliminating the need for explicit target selection interfaces or additional complex controls.

AI summary
A method of controlling a head mounted display (HMD) according to one embodiment of the present specification includes the steps of outputting visual information via a display unit, outputting auditory information via an audio output unit, detecting a control input touching a first region or a second region of a temple of the HMD, if the control input is detected in the first region, setting the visual information as control target information, if the control input is detected in the second region, setting the auditory information as the control target information, controlling an output of the set control target information according to an attribute of moving of the control input, which moves in the first region and the second region while maintaining a contact with the temple of the HMD, and if the contact between the control input and the temple of the HMD is released, terminating a control for the output of the set control target information, wherein the first region corresponds to a region adjacent to the display unit of the temple and wherein the second region corresponds to a region adjacent to the audio output unit of the temple.
