Touch Panel Haptic Feedback via Vibration and Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch sensors, such as those in smartphones and car navigation systems, lack the tactile feedback and auditory cues that mechanical switches provide, resulting in a less satisfying operation experience for users.
Innovation Solution
An electronic apparatus comprising a touch panel, a vibration generator, and a sound generator, controlled by a processor to provide tactile vibrations and auditory feedback when the user interacts with the touch panel, enhancing the operational feedback through visual, tactile, and auditory means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a touch sensor is used instead of a mechanical switch, then the device structure is simplified and reliability is improved, but tactile feedback and auditory cues are lost resulting in poor operation experience
Solution Approach 1:
The patent implements multiple feedback mechanisms to restore tactile and auditory cues lost in touch sensor systems. A vibration generator provides tactile feedback by vibrating the touch panel when a touch is detected, while a sound generator produces audible click sounds to simulate mechanical switch feedback. This multi-sensory feedback approach resolves the contradiction by maintaining reliability through touch sensor technology while restoring operation experience through artificial feedback signals.
Solution Approach 2:
The patent introduces intermediary components (vibration generator and sound generator) that mediate between the touch sensor input and the user's sensory perception. These intermediaries translate electrical signals from the touch sensor into tactile and auditory sensations, bridging the gap between the simplified touch sensor system and the user's expectation of mechanical feedback.
2Ease of operation
If multiple feedback mechanisms (vibration, sound, visual) are added to the touch panel, then operation experience is improved, but device complexity increases
Solution Approach 1:
The patent employs a controller that manages multiple feedback functions (vibration control, sound generation, visual display changes) through a unified control architecture. This multi-functional approach allows the system to provide comprehensive feedback while minimizing control complexity by centralizing the management of all feedback mechanisms in a single control unit.
Solution Approach 2:
The patent combines multiple feedback mechanisms (vibration, sound, and visual elements) into an integrated feedback system controlled by a single controller. By merging these functions under unified control, the system achieves enhanced operation experience while avoiding the complexity that would arise from separate independent control systems for each feedback type.

AI summary
An electronic apparatus includes a touch panel, a vibration generator configured to vibrate the touch pane, a sound generator, and a controller. In response to an operation by the user onto the operation unit, in addition to a control provided to the vibration generator to cause the touch panel to vibrate, the controller performs (i) a control provided to the display screen to change displaying of the operation unit, or (ii) a control provided to the sound generator to generate a sound, or (iv) both the control provided to the vibration generator and the control provided to the sound generator.
