How touch screens work:
Capacitive touch screens work by using the electric field induction of the human body. When the finger touches on the metal layer, the capacitance of the contact will change, making the oscillator frequency connected to it change. By measuring the frequency change the touch position can be determined and information obtained.
Capacitive touch panels have a variety of applications in the field of robotics. They are widely used as human-machine interfaces (HMIs) that allow users to seamlessly interact with robots. Capacitive touch panels offer several advantages such as high sensitivity, precision and intuitive interface. It is increasingly being used in robots, where its unique benefits provide a more efficient, intuitive and intelligent interaction.
- High sensitivity and precision:
Capacitive touch panels detect touch points through capacitance, with high sensitivity, and can respond quickly to touch operations.
The touch panel can accurately detect the touch position and support multi-touch, which enables the robot to recognise and respond to complex gesture operations, such as rotation, zoom, etc., and improves the accuracy and flexibility of interaction.
- Durable:
Capacitive touchscreens can withstand more use and wear and tear than traditional mechanical button components, extending the life of the robot.
The surface of the touch screen is usually made of high-strength glass material, which can effectively prevent scratches and breakage, and adapt to a variety of complex working environments.
- Waterproof and dustproof:
Capacitive touch panels excel in dustproof and waterproofing, and are able to work stably in humid or dusty environments, expanding the scope of application of robots in different fields.
- Intuitive and convenient operation:
Capacitive touch screen operation is intuitive, the user does not need to press the screen, just gently touch to achieve interactive operation, reducing the difficulty of use and improving the user experience.
- Easy integration and maintenance:
Capacitive touch screen can be easily integrated into the robot's control system to achieve seamless connection with other components.
Maintenance costs are relatively low, and once a fault occurs, it can be quickly diagnosed and repaired.
