HMD Captured Image Data Control via Operation Step Permissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display (HMD) systems lack the ability to control the usage of captured image data securely and conveniently, particularly in work environments where information leakage is a concern, due to uniform limitations in the basic control program.
Innovation Solution
A head-mounted display apparatus with a storage unit for control data defining operation steps, an imaging unit for capturing external scenes, and a control unit that executes the operation flow, allowing for controlled usage of captured image data by setting permissions for each operation step, switching the imaging unit's state, and managing storage and transmission of the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capturing is limited by a function of a basic control program (OS), then security is improved, but user convenience deteriorates
Solution Approach 1:
The patent segments the capturing control into different operation steps within an operation flow. Each operation step can have independent capturing permission settings, allowing the system to enable capturing only when needed for specific tasks while disabling it otherwise. This granular control resolves the contradiction by providing both security (capturing is disabled by default) and convenience (capturing is automatically enabled when required by the operation flow).
Solution Approach 2:
The patent implements dynamic control of capturing permissions based on the current operation step. The capturing permission is not fixed but changes dynamically according to the execution state of the operation flow. This dynamic approach allows the system to adapt capturing permissions to the current context, achieving both security and user convenience.
2Reliability
If capturing is uniformly limited, then information leakage is prevented, but productivity deteriorates
Solution Approach 1:
The patent divides the operation flow into multiple operation steps, each with independent capturing permission settings. This segmentation allows capturing to be enabled only for specific steps where it is necessary for work completion, preventing information leakage in other steps while maintaining productivity in steps that require capturing.
Solution Approach 2:
The patent pre-defines the operation flow with capturing permissions set for each operation step before execution. This preliminary configuration ensures that capturing is automatically permitted or restricted based on the current step, eliminating the need for manual intervention and maintaining high productivity while ensuring information security.

AI summary
An HMD mounted on a head of a user includes a storage unit configured to store process flow data that defines a process flow including a plurality of work blocks in which an order of execution is predetermined, a camera configured to capture an external scene, and a control unit configured to execute the process flow according to the process flow data. At least any one of the plurality of work blocks in the process flow data includes a setting that determines whether use of captured image data of the camera is permitted. The control unit controls, when executing the process flow, propriety of using the captured image data in each of the work blocks according to the setting of the process flow data about the work block.
