Fujitsu has unveiled an interesting prototype haptic feedback tablet at MWC 2014. The tablet has special technology that makes the screen feel smooth or rough, allowing the user to feel images on the screen. The technology behind the haptic system was developed at Fujitsu Laboratories. The tech is able to create tactile sensations by varying the friction between the touchscreen and the user’s finger.
How the Technology Works
The technology uses ultrasonic vibration on the surface of the screen to create a high-pressure air layer between the user’s finger and the screen. The air between the screen and the finger reduces friction, creating a floating effect. This allows the screen to have a slippery sensation. Fujitsu is then able to cycle that air cushion at a fast rate, creating the ability to make a rough-feeling screen.
The ultrasonic vibrations are finely tuned to produce different textures, making it possible for users to experience a variety of tactile sensations. For instance, when viewing an image of sandpaper, the screen can be made to feel rough, while an image of silk can feel smooth. This opens up a wide range of possibilities for interactive applications, from gaming to virtual shopping experiences.
Applications and Future Prospects
Fujitsu says that it has worked to reduce the power needed by the haptic system. The tech is integrated into a tablet on display at MWC 2014. The tablet allows the user to feel CDs on the screen and gives the user the feeling of plucking strings on a Japanese harp on the screen. Fujitsu wants to commercialize the tech by 2015.
The potential applications for this technology are vast. In the realm of education, students could feel the texture of historical artifacts or geological samples, enhancing their learning experience. In e-commerce, customers could feel the fabric of clothes before making a purchase, providing a more immersive shopping experience. The gaming industry could also benefit significantly, offering players a more tactile and engaging experience.
Moreover, this technology could be a game-changer for accessibility. For visually impaired users, the ability to feel different textures on a screen could provide a new way to interact with digital content, making technology more inclusive.
Fujitsu’s commitment to reducing the power consumption of the haptic system is also noteworthy. One of the challenges with advanced touchscreen technologies is the additional power they require, which can drain battery life quickly. By focusing on energy efficiency, Fujitsu aims to make this technology practical for everyday use.
In addition to the tactile feedback, Fujitsu is exploring ways to integrate this technology with other sensory feedback systems, such as auditory and visual cues, to create a more comprehensive multi-sensory experience. This could lead to the development of new types of user interfaces that are more intuitive and engaging.
Fujitsu’s haptic feedback tablet represents a significant step forward in touchscreen technology. By allowing users to feel different textures on a screen, it opens up new possibilities for interaction and engagement. As Fujitsu continues to refine and commercialize this technology, we can expect to see it integrated into a wide range of applications, from education and e-commerce to gaming and accessibility. The future of touchscreens is not just about what we see, but also what we feel.
