HAPTIC FEEDBACK SUBSTRATE, HAPTIC FEEDBACK APPARATUS AND HAPTIC FEEDBACK METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17620546 titled 'HAPTIC FEEDBACK SUBSTRATE, HAPTIC FEEDBACK APPARATUS AND HAPTIC FEEDBACK METHOD
Simplified Explanation
The present disclosure describes a haptic feedback substrate, apparatus, and method that allow for local control and switching of vibrations to provide different haptic perceptual signals.
- The haptic feedback substrate includes an actuator and multiple vibration units connected to the actuator.
- Each vibration unit has a different inherent frequency.
- The actuator generates a vibration signal and drives the vibration unit with a target inherent frequency to resonate.
- The difference between the target inherent frequency and the frequency of the vibration signal is within a present threshold.
- By controlling the actuator to generate the vibration signal, the vibration unit with a frequency close to or equal to the vibration signal is driven to resonate, providing local haptic feedback.
- The vibration units have different inherent frequencies, allowing for sequential generation of vibration signals with different frequencies to obtain different haptic perceptual signals.
- This technology reduces the size of a touch feedback module, making touch feedback devices more portable and intelligent.
Potential Applications
- Mobile devices: This technology can be applied to smartphones, tablets, and other mobile devices to provide localized haptic feedback for enhanced user experience.
- Gaming: The haptic feedback substrate can be used in gaming controllers to provide realistic and immersive tactile feedback during gameplay.
- Virtual reality: By integrating this technology into virtual reality systems, users can experience more realistic sensations and interactions within virtual environments.
- Medical devices: Haptic feedback can be incorporated into medical devices to provide tactile guidance and feedback during surgical procedures or rehabilitation exercises.
Problems Solved
- Size limitations: The technology reduces the size of touch feedback modules, making them more compact and portable.
- Limited haptic feedback options: By allowing for local control and switching of vibrations, this technology provides a wider range of haptic perceptual signals, enhancing the user experience.
- Lack of portability: The smaller size of the touch feedback module makes touch feedback devices more portable and convenient for use in various applications.
Benefits
- Enhanced user experience: The ability to provide localized haptic feedback and different haptic perceptual signals improves the overall user experience in various applications.
- Compact and portable: The reduced size of the touch feedback module makes it easier to integrate into different devices and enhances portability.
- Intelligent control: The technology allows for intelligent control and switching of vibrations, providing more precise and customizable haptic feedback.
Original Abstract Submitted
The present disclosure provides a haptic feedback substrate, a haptic feedback apparatus and a haptic feedback method. The haptic feedback substrate comprises an actuator and a plurality of vibration units connected to the actuator, wherein each vibration unit has a different inherent frequency, the actuator is configured to generate a vibration signal and drive the vibration unit with the inherent frequency being a target inherent frequency to resonate, and a difference between the target inherent frequency and a frequency of the vibration signal is less than or equal to a present threshold. By controlling the actuator to generate the vibration signal, the vibration unit with inherent frequency being close to or equal to the frequency of the vibration signal is driven to resonate, thereby realizing local haptic feedback. The vibration units have different inherent frequencies, so the actuator may be controlled to sequentially generate vibration signals with different frequencies to realize local control and switching of the vibrations of the multiple vibration units to obtain different haptic perceptual signals. The present disclosure reduces the size of a touch feedback module and makes a touch feedback device more portable and intelligent.
