Head-Mounted Display Tapping Control via Sensor Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted displays (HMDs) require additional controllers for controlling events on the displayed information, limiting user interaction without external input devices.
Innovation Solution
A head-mounted display system that utilizes tapping as an input signal, detected by a sensor unit and processed by a control unit to change image characteristics such as kind, output, form, and playback speed, eliminating the need for external controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional controllers (touch pad, game pad) are used to control events on displayed information, then control functionality is improved, but device complexity and user convenience deteriorate due to requiring external input devices
Solution Approach 1:
The patent merges the control function with the HMD device itself by enabling direct interaction with the display surface. The display unit is configured to detect user input directly, eliminating the need for separate controllers. This integration allows the HMD to function as both display and control device, resolving the contradiction between control versatility and device complexity
Solution Approach 2:
The HMD device is designed to perform multiple functions: displaying information and detecting user input for event control. The display unit serves dual purposes as both output device and input sensor, enabling the single device to handle both information presentation and interaction control, thereby improving versatility without adding separate components
2Measurement precision
If additional controllers are required for controlling events, then control precision is improved, but ease of operation deteriorates due to needing external input devices
Solution Approach 1:
The HMD device serves itself by incorporating input detection capability directly into the display unit. The display surface detects user input (such as touch or proximity gestures) and processes it for event control without requiring external controllers. This self-service approach improves ease of operation while maintaining control precision through direct user-device interaction
3Extent of automation
If motion detection is used for viewpoint control, then automation is improved, but adaptability deteriorates because motion is limited to viewpoint changes only
Solution Approach 1:
The patent implements dynamic functionality where the display unit can detect multiple types of user input (touch, proximity gestures, etc.) and respond with different control actions. The system dynamically adapts its response based on the type and location of input detected, enabling diverse control applications beyond fixed viewpoint control, such as event selection, information scrolling, and device setting adjustments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to interact with and control image events on the HMD solely through tapping, enhancing user experience by providing intuitive control without additional hardware.
Implementation Method 1
a sensor unit; and a control unit for measuring a tapping applied to the head-mounted display from a measurement value obtained by the sensor unit
Implementation Method 2
the measurement value and the reference value may be based on at least one of a motion of a user who is wearing the head-mounted display and sound generated at the head-mounted display
Data Source
AI summary
A head-mounted display (HMD) may include a sensor unit, a display unit configured to display an image, and a control unit for measuring a tapping applied to the head-mounted display from a measurement value obtained by the sensor unit, and controlling the image displayed on the display unit by using the tapping as an input signal. When the HMD is used, an image displayed on the HMD may be controlled by using a tapping applied to the HMD as an input signal, and thus, an event may be processed without using any additional controller.
