Touch Panel Vibration Feedback for Direction Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in accurately performing direction input operations on touch panels without tactile feedback, as they cannot discern changes in input direction, leading to confusion and errors.
Innovation Solution
A game control device and system that determines the region of touch on a touch panel and causes the panel to vibrate when the touch position changes, providing tactile feedback to confirm direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a virtual directional button or lever is used on a touch panel, then the device structure is simplified and portability is improved, but the user cannot obtain tactile feedback when operating, making it difficult to grasp whether the input direction has actually changed
Solution Approach 1:
The patent applies mechanical vibration to the touch panel by causing it to vibrate in response to detected touch positions. When the user touches different regions corresponding to different directions, the touch panel generates tactile vibrations that provide feedback to the user, confirming that the direction input has been registered. This resolves the contradiction by maintaining the simplified virtual button structure while adding tactile feedback capability through vibration.
2Adaptability or versatility
If a virtual directional button is displayed on a touch panel screen, then no physical directional button is needed, but the user cannot discern changes in input direction through tactile sensation
Solution Approach 1:
The patent implements a feedback mechanism where the touch panel provides tactile vibration feedback in response to user touches. When the user touches a region corresponding to a specific direction, the system detects the touch position and causes the panel to vibrate, providing immediate tactile confirmation that the input has been registered. This feedback loop compensates for the loss of tactile information in virtual buttons while maintaining input method versatility.

AI summary
A game control device comprising at least one processor configured to: receive direction input by determining which region, among a plurality of regions set so as to respectively correspond to a plurality of directions, a touch position detected by a touch panel is included in; determine whether or not the touch position has changed from being in one region to being in another region among the plurality of regions; and cause the touch panel to vibrate if the touch position has changed from being in the one region to being in the another region.
