For the past several years technology companies have been working to improve tablet and Smartphone displays. Today life is still without Smartphones, Tablets, and laptop. People spend most of their time on these devices and always think more in terms of technology. So far, most of the company’s efforts have focused on improving screen resolution and pixel density, but this year at Mobile World Congress (MWC) Japanese computer giant Fujitsu moved beyond this, demonstrating a touchscreen technology designed to emulate the textures of objects and materials by introducing first technology to use ultrasonic vibrations to give tactile sensations “Fujitsu Haptic Tablets”.
The Fujitsu Haptic Tablet screen has sensors under the display, which detect when a finger is touching the screen and emit low-powered, regulated, ultrasonic vibrations. Thus Fujitsu Technology work by inducing ultrasonic vibration on the surface of the touchscreen, by this a high-pressure layer of the air is created between the screen’s surface and the user’s fingertip. This method reduces friction, thus creates a floating effect. Taking the advantage of this phenomenon makes it possible to create a slippery sensation on a touchscreen display that had been previously difficult to achieve.
While vibrations in the ultrasonic band require a significant amount of energy, Fujitsu has developed a technology that induces vibrations efficiently at mobile device sizes, and successfully produced a prototype that creates these tactile sensations. It is assumed, this effect would drain a device’s battery, but that will not happen with this Fujitsu Haptic Tablet. Fujitsu provides demo unit that lets us try the haptic display in a variety of scenarios. These included a digital dial lock on a vault, a set of strings on a musical instrument, a crocodile’s back and a sand box.
By testing the dial lock demo, you will notice with the haptic display only works if you interact with it using with one finger. Trying to physically grab the digital lock with two fingers as like you would do in real life; the display only reacted to our index finger. The sand box demo has proved that the display is able to deal with multi-layer textures. This demo required you to brush sand off a mosaic image, and you found the haptic display offered convincing feedback on both layers, changing the feel of the underlying mosaic’s image after you had rubbed the sand off.
With Fujitsu Haptic Tablet we are approaching an era in which simulated realities will be almost as real as the actual reality in which we live every day. This device by itself has the potential to change things in a variety of ways, and seeing just what effects it has should be quite exciting in its own right. Till Fujitsu did not reveal when one can expect to see its haptic display technology implemented in a commercial product, to feel the real experience, but it is expected till end of 2014 or in the early 2015. The Fujitsu Haptic tablet is quite impressing. By adding this tactile sensation feature, Fujitsu is offering customers a totally original experience that breaks new ground in usability and sensory expressiveness.
