Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) providing virtual reality (VR) to users lack effective kinesthetic and tactile feedback during gameplay, which diminishes the entertainment experience.
Innovation Solution
An information processing apparatus that includes an operation information acquisition section and a control section to generate driving data for kinesthetic and tactile feedback, using a movable section and vibration section in response to user input, simulating virtual interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If kinesthetic feedback and tactile feedback are provided through an operation apparatus in VR, then the entertainment value and physical sensation are enhanced, but the device complexity increases
Solution Approach 1:
The operation apparatus is divided into distinct functional components: a movable section that provides kinesthetic feedback through movement, and a vibration section that provides tactile feedback through vibration. This segmentation allows each component to specialize in one type of feedback, improving overall feedback effectiveness while keeping individual components relatively simple.
Solution Approach 2:
The operation apparatus is designed to serve multiple functions: it acts as both a control device for user input and a feedback device that delivers both kinesthetic and tactile sensations. This multi-functionality reduces the need for separate dedicated feedback devices, thereby managing complexity while enhancing the VR experience.
2Ease of operation
If the movable section moves in response to user input, then kinesthetic feedback is provided, but the device complexity and control difficulty increase
Solution Approach 1:
The movable section is configured to move in response to user input operations, creating a direct feedback loop where the user's action immediately produces a physical sensation. This real-time feedback mechanism enhances ease of operation by making the connection between input and output intuitive, while the simplicity of the movement mechanism keeps complexity manageable.
3Reliability
If the vibration section vibrates to provide tactile feedback, then the entertainment experience is enhanced, but the use of energy increases
Solution Approach 1:
The vibration section provides tactile feedback through periodic vibration rather than continuous operation. By activating vibration only when needed for specific feedback events during gameplay, the system maintains high tactile feedback quality while significantly reducing overall energy consumption compared to continuous vibration.

AI summary
An operation information acquisition section acquires operation information indicating movement of an operation apparatus being held by a user's hand. The operation apparatus includes a kinesthetic sense presentation section that presents a kinesthetic sense to the user's hand and a tactile sense presentation section that presents a tactile sense to the user's hand. A control section controls movement of a virtual device corresponding to the operation apparatus in a space where a virtual object exists, according to the operation information. The control section generates first driving data for driving the kinesthetic sense presentation section and second driving data for driving the tactile sense presentation section, on the basis of a relation between the virtual device and the virtual object.
