Haptic Stylus NFC Vibration Feedback for Touchscreens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic input devices lack effective methods for providing vibrational feedback and haptic effects, particularly in portable devices with touch screens, which limits user interaction and immersion in applications like flash content, web browsing, and gaming.
Innovation Solution
A method and apparatus that utilize near field communication to transmit and receive vibration commands between electronic devices, allowing for vibrational feedback and haptic effects through a second electronic device with vibration members, such as a stylus, to enhance user interaction with touch screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is used for input and output, then user interaction capability is improved, but haptic feedback capability deteriorates
Solution Approach 1:
The patent introduces a second electronic device (such as a stylus or external haptic device) as an intermediary to provide haptic feedback to the user. This external device receives vibration commands from the first electronic device (touch screen device) and generates tactile sensations, thereby mediating between the touch screen interface and the user's tactile perception needs.
2Weight of moving object
If portable electronic devices are made smaller and lighter, then portability is improved, but vibration feedback capability deteriorates
Solution Approach 1:
The patent extracts the vibration feedback function from the main portable electronic device and relocates it to a separate second electronic device. This allows the primary device to remain small and lightweight while the haptic feedback capabilities are housed in an external accessory that can be attached or detached as needed.
3Adaptability or versatility
If near field communication is used to transmit vibration commands, then wireless communication capability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic or event-driven near field communication for transmitting vibration commands, rather than maintaining continuous communication. The first electronic device activates NFC transmission only when vibration events occur during application execution, thereby reducing overall energy consumption while maintaining wireless communication capability when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables intuitive haptic feedback and immersive user experiences by providing vibrational cues in response to user inputs on touch screens during various applications, improving interaction accuracy and engagement.
Implementation Method 1
A vibration command is then received by the second electronic device from the first electronic device, and the second electronic device is vibrated in response to the vibration command
Data Source
AI summary
A method of operating a haptic-enabled electronic device includes detecting an input interaction between the haptic-enabled electronic device and a touchscreen-enabled electronic device selecting a vibration command in associated with the input, and vibrating the haptic-enabled electronic device in response to the vibration command.
