Wearable Controller and Hand Imaging Control Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for head-mounted displays (HMDs) in mixed reality and virtual reality techniques cannot select the appropriate application when users control the device without an input device, leading to suboptimal user experience.
Innovation Solution
A control device and method that selects between a first control mode based on hand state imaging and a second control mode involving physical contact with a wearable controller, allowing users to choose their preferred control method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control device uses hand state imaging for control, then the user can control without physical contact, but the control precision and reliability deteriorate compared to physical input devices
Solution Approach 1:
The system dynamically switches between first control mode (hand state imaging) and second control mode (physical controller) based on real-time detection of controller presence and user needs. This dynamic adaptation allows the system to use contactless control when convenient while falling back to precise physical control when needed, resolving the contradiction between ease of operation and control precision.
2Adaptability or versatility
If the control device supports multiple control modes, then the adaptability to user preferences improves, but the device complexity increases
Solution Approach 1:
The control system is segmented into distinct first control mode (hand state imaging) and second control mode (physical controller), each with dedicated processing pathways. The selection unit acts as a gateway that routes to the appropriate segment based on controller detection, managing complexity through structured division rather than monolithic design.
Solution Approach 2:
The control device achieves multi-functionality by integrating both hand state imaging control and physical controller support within a single unified system. The selection unit and processing unit work together to provide universal control capabilities that adapt to different user preferences and scenarios without requiring separate devices.
3Speed
If the control device continuously monitors hand state, then the responsiveness to user input improves, but the power consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic detection triggered by controller presence status changes. The imaging device and controller detection operate in a periodic manner, activating hand state monitoring only when the controller is detected as absent or when mode switching is required, thereby reducing overall power consumption while maintaining responsiveness when needed.

AI summary
A control device controls an electronic apparatus. The control device selects either one of a first control mode and a second control mode as a control mode to control the electronic apparatus. The control device 1) controls the electronic apparatus in accordance with a state of a specific portion of the user determined based on imaging by an imaging unit in a case where the first control mode is selected, and 2) controls the electronic apparatus in accordance with an operation of the user involving a physical contact with a specific operation member in a case where the second control mode is selected. The specific operation member is included in a controller, and the controller is wearable on the hand of the user.
