Japanese electronics conglomerate Sony is reportedly working to integrate biometric sensors and LCD touch-screen in the control pads of the company's upcoming gaming console PS4 (PlayStation 4).

Citing an unnamed senior developer connected to Sony PS4, UK-based magazine CVG (Computer and Video Games) reported that the Sony R&D department is testing to integrate LCD touch-screen and biometric sensors on the grips of PS4's controller pad.

Another source related to the Japanese company said that PlayStation developers are "trying to emulate the same user interface philosophies as the PS Vita (handheld gaming console)", reported the CVG.

Another one of CVG's major disclosure was that Sony will be abandoning the DualShock controllers in favour of LCD touch screen controllers in its next generation PlayStation 4 console configurations.

DualShock is currently used as a vibration-feedback game pad in all the PlayStation consoles.

DualShock game pad has been the primary console controller of PlayStation consoles ever since it was introduced in 1997 for PS1. It has been upgraded twice since its debut 16 years ago.

In 2000, an improved DualShock version 2 was introduced as a standard configuration unit of the PlayStation 2 console package.

the DualShock version 3 was released in 2008, two years after the PS3 debut.

Now, the next generation gaming console PS4, code-named 'Orbis', is expected to ship with an all new LCD touch-screen game pad equipped with biometric sensors.

The speculations of PS4's debut has also created quite a buzz in the gaming industry. Many technology blogs have predicted that the PS4 is most likely to be unveiled at the upcoming international gaming convention E3 (Electronic Entertainment Expo) in June at the Los Angeles Convention Center.

According to various reports, Sony's rival Microsoft is also expected to unveil its next generation Xbox 720 (code-named Durango) in June at the E3 gaming convention.
