Head-Mounted Processing Apparatus With Camera-Keyed Content Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The convenience of using head-mounted processing apparatuses is reduced due to the time-consuming selection operations required to access content, especially when menu hierarchies are deep, and these operations can diminish the user's sense of immersion.
Innovation Solution
The apparatus includes a content controller with a key content pair information register and restorer that associates the state of content at event occurrence with a registration key, allowing automatic restoration of the content state upon activation by matching camera images or sensor data with stored key content pair information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user performs selection operations using a remote controller to access content, then the user can select desired content, but it takes time to search for the remote controller and perform selection operations, reducing convenience
Solution Approach 1:
The system performs preliminary actions by automatically restoring the content state that was active before the HMD was turned off. The content controller stores the previous content state information and automatically retrieves it upon activation, eliminating the need for users to perform selection operations after turning on the device.
Solution Approach 2:
The system serves itself by automatically managing content state restoration without requiring user intervention. The content controller autonomously detects the previous content state, retrieves stored information, and restores the content automatically, making the system self-sufficient in maintaining user experience continuity.
2Adaptability or versatility
If the menu hierarchy is deep to provide comprehensive content selection, then more content can be organized and accessed, but it requires more search operations and increases the time to find target content
Solution Approach 1:
The system performs preliminary action by pre-storing the content state information including the specific content that was active before shutdown. When the HMD is activated, this stored information is automatically retrieved and applied, bypassing the need for users to navigate through deep menu hierarchies to find their previous content.
3Ease of operation
If the user performs selection operations to access content, then the user can choose desired content, but the operation itself diminishes the user's sense of immersion
Solution Approach 1:
The system performs self-service by automatically restoring the previous content state without requiring any user selection operations. This maintains the user's immersive experience by eliminating interruptions where the user would need to interact with menus or remote controllers, allowing seamless transition back into the content.

AI summary
When an instruction from the user is received or when an event occurs and the head mounted processing apparatus is terminated, a key content pair information register is configured to associate a state of content at the time of the event occurrence with a registration key obtained from an image of a camera at the time of the event occurrence to store them in a memory as key content pair information. When the head mounted processing apparatus is activated, a key content pair restorer is configured to determine whether an image of the camera at the time of apparatus activation is made conformity with the registration key or not on the basis of the key content pair information, and restore the state of the content corresponding to the registration key made conformity with the image in a case where the image is made conformity with the registration key.
