With the continuous upgrading of electronic products and the diversification of consumer needs, multi-touch technology has become an important factor in enhancing product competitiveness. Multi-touch technology can meet the user's demand for a more natural, intuitive and convenient interaction method, and is therefore widely used in smart phones, tablet PCs, laptops, smart TVs and other electronic products. With the advancement of technology, multi-touch technology will become more mature and popular in the future, promoting the further development of the electronics market.
Multi-touch technology not only supports the basic operations of single-touch (e.g., clicking, sliding), but also supports a variety of gestures such as double-click, press, pan, scroll, rotate and other operations. This diversified touch provides users with a richer and more flexible interactive experience. For example, when browsing the web, users can zoom in and out of the page with two fingers; when playing games, more complex operations can be achieved through multi-touch. With the continuous innovation of technology, multi-touch technology will support more kinds of gestures in the future to further enhance the user interaction experience.
Multi-touch technology has a wide range of applications, not limited to the consumer electronics field. It also has a wide range of applications in infotainment, radar interactive systems, LCD monitors, multi-touch walls, electronic whiteboards, intelligent conference panels, smart homes and other fields. For example, in the field of education, multi-touch technology can be applied to electronic whiteboards to achieve multi-user simultaneous operation, interactive teaching and other functions; in the field of smart home, multi-touch technology can be used in intelligent control panels to achieve convenient control of smart home equipment. With the continuous development of the Internet of Things and artificial intelligence technology, multi-touch technology will be applied in more fields.
Can touch screens support customised touch points? The answer is obviously yes. Then, the benefits of touch screen support custom multi-touch?
1. Enhance user experience: Customised touch points can better meet the needs of specific application scenarios, such as gaming, design, medical and other fields, which require more accurate and flexible multi-touch operation, thus enhancing the user interaction experience.
2. Enhance product competitiveness: Through customised touch points, enterprises can produce products with differentiated competitive advantages to meet the diversified needs of different users in the market and enhance the market competitiveness of their products.
3. Optimise cost-effectiveness: customising the number of touch points according to actual needs can avoid unnecessary waste, reduce production costs and improve the cost-effectiveness of products.
Capacitive touch screen multi-touch technology principle:
Capacitive touch screen through the glass screen coated with a transparent film conductor layer (such as ITO, that is, nano indium tin metal oxide), and in the conductor layer plus a piece of protective glass, forming a double-glass design to protect the conductor layer and the inductor. This thin film conductor layer and the human body between the electric field can form a coupling capacitance. When the finger or other conductive objects touch the screen, will change the capacitance value of this coupling capacitance, thus triggering the response of the touch screen.
To achieve multi-touch, capacitive touch screen needs to increase the mutual capacitance of the electrode. Specifically, the screen is divided into chunks, and in each region to set up a set of mutual capacitance module, these modules are working independently. When multiple fingers touch the screen at the same time, each touch point will affect the coupling capacitance between the electrodes in its vicinity, thus changing the capacitance between these electrodes.
Multi-touch specific applications:
On gaming devices, customised touchscreens with a high number of touch points are often required to support more complex game operations and richer interactive experiences. For example, some high-end gaming tablets or gaming consoles may use customised multi-touch screens that support up to 10 points or even more simultaneous touches to meet the diverse operational needs of players in games.
In the field of industrial control, touch screen as an important interface for human-computer interaction, the customisation of its touch points is also particularly important. For example, in the automated production line, the operator may need to control multiple devices or parameters at the same time, then it is necessary to customise the touch screen with enough touch points in order to achieve efficient and accurate operation and control.
In summary, the touch points of the touch screen to support customisation has a variety of benefits, the technical principles of which are mainly dependent on the touch screen sensing technology and production process. Through specific examples can be seen, customised touch screen in a number of fields have a wide range of application prospects.
