Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mixed reality environments, users face difficulties in clearly indicating points on virtual images with existing helmet devices, as the position of the user's finger cannot be directly seen, leading to confusion during discussions.
Innovation Solution
An indicator device with a light source unit, positioning elements, and a control unit is integrated into a mixed reality device, allowing the light source unit and positioning elements to be disposed on different axes, enabling controlled light emission and recording of motion trajectories within the mixed reality space to facilitate clear indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user points a position on a virtual image using a mixed reality helmet, then the user can interact with the virtual environment, but the position being pointed cannot be seen by other users, causing confusion
Solution Approach 1:
The patent introduces an indicator device as an intermediary tool between the user's finger and the virtual image. The indicator device includes a light source unit that emits light to mark the pointing position, and positioning elements that enable spatial localization. This intermediary device makes the invisible finger position visible to others through light emission and positional tracking, resolving the information loss problem while maintaining interaction capability.
2Device complexity
If the light source unit and positioning elements are disposed on the same axis, then the structure is simplified, but the positioning accuracy and indication clarity are reduced
Solution Approach 1:
The patent deliberately adopts an asymmetric arrangement where the light source unit and positioning elements are disposed on different axes rather than the same axis. This asymmetric configuration improves positioning accuracy and indication clarity by separating the light emission function from the positioning reference function, allowing the system to more accurately determine the spatial position of the indicator and the direction of light emission.
3Loss of information
If the light-emitting state is continuously activated, then the indication is always visible, but the energy consumption increases
Solution Approach 1:
The patent implements periodic action by controlling the light source unit to emit light in specific patterns (continuous, intermittent, or flashing) based on operational needs. The control unit can switch between different light-emitting states, allowing the system to maintain indication visibility when needed while reducing energy consumption during periods when indication is less critical. This periodic or conditional light emission resolves the contradiction between visibility and energy consumption.

Function Achieved in This Case
The solution effectively allows users to clearly indicate points on virtual images, enhancing discussion clarity and convenience by projecting and recording the light source's motion, thereby improving the usability of mixed reality devices in applications like medicine, maintenance, and remote teaching.

Data Source
AI summary
An indicator device is suitable for a mixed reality device. The indicator device includes a body, a light source unit, at least two positioning elements, a triggering unit and a control unit. The light source unit is disposed on the body and generates a light source. The two elements are disposed separately on the body, wherein the light source unit and the positioning elements are disposed on different axes. The triggering unit is disposed on the body and generates a trigger signal. The control unit is disposed inside the body and is connected to the light source unit and the triggering unit. The control unit receives the trigger signal to generate a first control signal, thereby controlling the light-emitting state of the light source.
