With the increasing popularity of interactive digital signage applications, touch screens have gradually become familiar to the general public. Interaction with digital signage through manual touch has become a recognized way. However, in order to meet the increasing interactive demand of the market, the future of touch screens will never stop at pure manual touch. Many research institutions have conducted more in-depth research on the interactivity of touch screens and have achieved good results.
Can you imagine that one day you will be able to "touch" physical objects through the touch screen? In fact, this day has already arrived. A few days ago, Disney researchers have developed a touch screen that can "deceive" the audience's sense of touch, allowing them to feel that they have touched the real objects on the screen through the touch screen, enhancing the audience's sense of presence.
Coincidentally. Researchers from the Bristol Interactive and Image Group of the British University have developed a force field that allows touch feedback with interactive technology, that is, touch operations can be realized without the user actually touching the touch screen. This system is called UltraHaptics, and it mainly relies on sound radiation, which makes the user’s hand in mid-air feel touched by the vibration of ultrasonic waves. Compared with traditional touch technology, this method undoubtedly deepens the application of human-computer interaction without affecting the simplicity and accessibility.
In the field of digital signage, the importance of interactive applications is self-evident. However, for now, the market's perception of it is still at the conceptual level. At the practical level, its value still needs to be explored. There are many obvious signs. The interactive digital signage that has been constructed has become a "face project". For example, some interactive digital signages installed in highly concentrated places such as airports and high-speed railway stations are still mainly responsible for unilateral information push tasks, and they have not really attracted the audience to interact with them.
An important reason for this embarrassing situation is that the so-called interactive digital signage still requires the audience to take the initiative and is too superficial. With the popularization of applications and the passing of novelty, naturally it can no longer stimulate the audience's interest in interaction. Nowadays, the deepening and diversification of touch technology has greatly improved the initiative of the audience and can more reflect the meaning of interaction.
Compared with traditional digital signage, an important reason why interactive digital signage is so popular is that information push is more active and flexible, especially with the gradual expansion of retail market applications, this necessity becomes more prominent. With the vigorous promotion of manufacturers, the market demand for interactive digital signage has been formed, and technical improvements will give users greater application confidence. It is foreseeable that, driven by the innovation of touch technology, interactive digital signage will enter a substantial popularization period.
