Operation Device Tactile Feedback Control via Edge Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operation devices with tactile force sense presenting functions are limited in their ability to present tactile feedback in various modes due to the need for parameter calculation and transmission, resulting in delayed and restricted tactile experiences.
Innovation Solution
An operation device with a movable portion that receives control mode and information instructions, allowing for direct control of tactile feedback using a control unit, interface, and communication unit to present tactile force senses in multiple modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operation device sends operation content to the main unit for parameter calculation and tactile force sense control, then the tactile force sense can be controlled based on calculated parameters, but the response time is delayed and the variety of tactile modes is limited
Solution Approach 1:
The patent extracts the tactile force sense control function from the main unit and relocates it to the operation device. The operation device now includes a control unit that directly controls the actuator based on operation content detected by its own detection unit, eliminating the need to send data to the main unit for parameter calculation. This extraction of the control function to the edge device (operation device) enables immediate tactile feedback without communication delays, resolving the contradiction between response time and control capability.
2Ease of operation
If the main unit calculates parameters and sends control instructions to the operation device, then centralized control is maintained, but the operation device has limited autonomy and response speed
Solution Approach 1:
The patent segments the control system into two independent parts: the main unit that handles game logic and high-level decisions, and the operation device that handles local detection and tactile feedback control. The operation device's control unit independently processes operation content detected by its detection unit and directly controls the actuator without requiring main unit intervention. This segmentation enables fast local responses while maintaining the main unit's centralized control for overall game management, balancing responsiveness and architectural complexity.

AI summary
An operation device has a movable portion movable between a first position and a second position. The movable portion is operated by a user while the operation device is gripped by the user. The operation device receives information identifying a control mode and control information defined for each control mode as an instruction related to control of a tactile force sense, and controls the tactile force sense presented to the movable portion by using the received control information in the control mode identified by the received information.
