Increase the design and application opportunities in many places, such as outer space or underwater due to the limitations of traditional input devices, so that touch screen technology can be used. The touch screen is directly mounted on the surface of the display or around it, so that there is no need to consider enough space or surface area to load a peripheral device. This has led to many new applications, such as car control and mobile communication equipment. For designers, this greatly increases the range of options for loading systems.
Touch screen technology does not need to add other input devices on the desktop or anywhere else, because the input devices have been integrated into the display. Especially when some devices are too compact to be equipped with keyboard or mouse, touch screen is a good choice. Handheld computers and PDAs are examples that are not suitable for using traditional input devices.
Many types of touch screens are very sturdy and durable, and are suitable for use in extremely harsh environments, which destroy traditional input devices. Therefore, it can be used in many places where computers were not suitable before. For example, harsh industrial environments and car repair rooms are the most suitable places for touch screen input.
Touch input also solves other problems faced by traditional input devices. 3 For example, some devices are used at night or in a dark environment, such as in-car controllers or safety and supervisory equipment. Touching an image on a bright display is easier and more accurate than using a keyboard in the dark, especially when people are driving.
Immediate response is small like other input devices such as mouse, trackball and joystick. The user does not need to adjust the hand movement between the moving input device and the corresponding arrow on the screen. Once the user makes a selection, the target will flash or switch to the corresponding screen, and the user can immediately see that the input has been accepted.
Simplify complex systems where large databases are involved, the touch system can simplify information by limiting the number of options or the amount of data displayed at a time. Touch the target step by step to guide the user through a series of complex processes.
Graphical interfaces of touch devices are usually designed with as few options as possible on one screen. Users will not be misunderstood by too much information at a time, because only useful options are provided on the screen.
Easy to operate Touch screen technology provides the quickest path to all digital media, it does not require cumbersome text descriptions. The touch information is rich in graphics and text, and the structure is clear, allowing users to see at a glance. Just touch the relevant button on the screen with your finger to enter the world of information. The touch screen allows a person without any training to use the computer immediately.
