The touch screen system software can come from the original manufacturer (such as an embedded operating system in a mobile phone), or it can be installed later (such as adding a touch screen to a traditional PC). The software should enable the touch screen and the system controller to work together. It will tell the product's operating system how to parse the touch event information from the touch controller. In PC application systems, most of the touch screen operations are like a mouse. This makes touching a certain position on the screen of the touch screen very similar to pressing the mouse continuously. In an embedded system, the embedded controller must compare the information that appears on the screen with the location where the touch is received.
As far as electronic products are concerned, the user interface design must take into account the user's five senses of vision, hearing, taste, smell and touch, on the one hand, and also consider the impact of user needs on the device or system on the other hand. At present, most of the products launched on the market separate the user's vision and touch.
From simple buttons or keys on computer keyboards, mobile phone keyboards, MP3 players, household appliances and even TV remote controls, to more advanced click and scroll features such as volume adjustment sliders, scroll wheels, and track pads, the output position (that is, The user's input or the result of the manipulation action) is completely different from the user's input position. If it can make the input and output, that is, the vision and touch are completely consistent, and this consistency of vision and touch is the advantage of the touch screen.
Although most people use sight and hearing to interact with computers, in some cases, touch is the most suitable. Today, computer technology is increasingly recognizing this and beginning to adopt haptic technology. The sense of touch in Greek means "grab or touch," which refers to the ability of a device to produce output that can be felt (rather than being seen or heard). The tactile output is usually force or vibration. Haptics can also be used to improve the visualization of data, enable users to browse massive amounts of data, and provide an additional communication channel.
The two important applications of haptics are virtual reality and remote operation. Although haptics is used in computer games at a high rate, it can also be applied in the field of industrial control. For example, the sense of touch allows users to touch and feel objects in computer-aided design (CAD), computer-aided manufacturing (CAM), and similar systems. The probe can send digital feedback signals to the design software, and all electronic control and braking systems can provide the operator with actual feedback, thus avoiding the weight and complexity of direct connections or power-assisted mechanical connections.
おそらく、触覚の最も単純な例は、ラジオをチューニングするためのノブに似たノブです。 モーターやブレーキユニットにこのようなノブを装備することで、さまざまなブレーキ装置、ハードブレーキ、さらには弾性ブレーキを設定することができ、これらすべての機能を必要に応じて変更することができます。
