Headset Motion Sensor for Hands-Free Pointing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display systems restrict mobility as they require one hand to operate the control device, limiting productivity in mobile units, especially when the unit is hand-held or mounted.
Innovation Solution
A headset with a built-in motion or inertial sensor that detects movement and translates it into corresponding directional data for a pointing device on a head-mounted display, allowing single-handed operation without needing to look away from the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pointing device is controlled using a mouse or joystick, then the pointing device can be operated, but the user's mobility is restricted and hands-free operation is not achieved
Solution Approach 1:
The patent replaces the mechanical control system (mouse or joystick) with an inertial sensing system. The inertial sensor detects movements of the mobile unit and translates them into pointing device movements, eliminating the need for mechanical control interfaces and enabling hands-free operation.
Solution Approach 2:
The mobile unit itself serves as the control device through its inertial sensor. The device detects its own movements and automatically translates them into pointing device control, making the system self-serving and eliminating the need for external control mechanisms.
2Productivity
If the mobile unit is hand-held, then mobility is maximized, but the other free hand is required to use the control device
Solution Approach 1:
The mechanical control interface is replaced with an inertial sensing system that automatically detects and translates mobile unit movements into pointing device control, enabling single-handed operation without requiring the user to manually operate a separate control device.
3Ease of operation
If the mobile unit is mounted, then stability is improved, but at least one hand is required to use the control device
Solution Approach 1:
The mounted mobile unit uses its own inertial sensor to detect movements and automatically control the pointing device, making the system self-serving and enabling hands-free operation that improves operational efficiency without requiring manual control input.
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 hands-free operation of a pointing device on a head-mounted display, enhancing mobility and productivity by allowing single-handed control and maintaining focus on the display.
Implementation Method 1
When the mobile device is moved, the sensor detects a direction of the movement to generate corresponding direction data
Implementation Method 2
The display displays to the user a corresponding movement of the pointing device which is determined as a function of the corresponding direction data
Data Source
AI summary
A headset comprises an arrangement and a display. The arrangement is situated at least partially on a head of a user. The display is coupled to the arrangement and capable of displaying a pointing device to the user. The headset is coupled to a mobile device which includes a sensor. When the mobile device is moved, the sensor detects a direction of the movement to generate corresponding direction data. The display displays to the user a corresponding movement of the pointing device which is determined as a function of the corresponding direction data.
