Head-Mounted Display Forehead Vibration Housing for Tactile Presence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays lack the ability to provide a heightened sense of presence through immersive experiences.
Innovation Solution
A head-mounted display incorporating a vibration motor housed in a front support section, which is connected to the main body and positioned on the user's forehead, providing vibrations that enhance the sense of presence by interacting with the user's sensory experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vibration motor is added to the head-mounted display, then the sense of presence is enhanced, but the device complexity increases
Solution Approach 1:
The patent combines the vibration motor with the existing housing structure of the head-mounted display. The motor is integrated into the housing that already supports the display panel, merging the tactile feedback function with the structural framework rather than adding a completely separate component system.
Solution Approach 2:
The housing structure serves multiple functions: it supports the display panel, provides structural integrity for the device, and now accommodates the vibration motor. This multi-functionality reduces the need for additional dedicated structures, thereby limiting the increase in device complexity.
2Reliability
If the vibration motor is placed on the forehead area, then the tactile feedback is enhanced, but the stability of motor operation deteriorates
Solution Approach 1:
The patent creates a dedicated localized housing structure specifically designed to accommodate the vibration motor in the forehead area. This localized structure provides the motor with a stable, isolated mounting environment that is optimized for its specific function while maintaining the overall device's balance and comfort.
Solution Approach 2:
The housing structure is designed in advance to provide a stable foundation for the vibration motor before operation begins. The structure includes appropriate mounting features and structural support that prevent motor instability during use, addressing potential stability issues before they occur during motor operation.
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
The vibration motor, when integrated into the display, effectively enhances the user's sense of presence by simulating tactile feedback, while being stably driven and reducing visual disturbances.
Implementation Method 1
a vibration motor 40, which is accommodated in the housing section 34c
