Head-Mounted Display Electrostatic Input Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted displays (HMDs) face challenges with portability and operability due to the need for dedicated input apparatuses and limited input options, which can lead to erroneous operations when the user cannot view the input apparatus.
Innovation Solution
A head-mounted display design incorporating a main body with a display section and an input operation section featuring a first detection element that electrostatically detects user input along a specific axis direction, guided by a first guide section that allows tactile recognition of the detection element's position and direction, eliminating the need for additional input devices and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dedicated input apparatus is provided with the HMD, then input operations can be performed, but portability deteriorates due to the need to carry the input apparatus together with the HMD
Solution Approach 1:
The input operation section is merged into the main body of the HMD, integrating the detection element and guide section directly into the head-mounted display structure. This eliminates the need for a separate dedicated input apparatus while maintaining full input functionality, thereby resolving the contradiction between input capability and portability.
2Ease of operation
If buttons are provided on the HMD as input apparatus, then input operations can be performed, but the occupation area increases which affects the design
Solution Approach 1:
The mechanical button system is replaced with an electrostatic detection element that senses input operations through electrostatic changes. This substitution eliminates the need for physical buttons, reducing the occupation area while maintaining input functionality. The detection element can sense touches or presses without requiring the space needed for mechanical button structures.
3Ease of operation
If the user performs input operations on the HMD, then operations can be executed, but the user cannot view the input apparatus and may perform erroneous operations
Solution Approach 1:
A guide section is introduced as an intermediary between the detection element and the user's finger. This guide section provides tactile feedback and guidance, allowing the user to locate and operate the input area accurately through touch without needing to visually confirm the position. The guide section mediates the interaction, ensuring reliable operations even in dark environments or when the display is not visible.
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
This configuration enhances the portability and operability of the HMD by allowing seamless input operations without the need for external devices and reduces the risk of errors, even when the user cannot visually confirm the input position.
Implementation Method 1
a first detection element that extends in a first axis direction and is provided in the main body and electrostatically detects an operation position in the first axis direction
