Five unique output devices

Devices that can revolutionize your life !

What is an output device?

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form

1. FFL

Engineers claim their new ultra-thin speakers, as well as looking good and being easy to conceal, will also deliver clearer, crisper sound. Flat, flexible loudspeakers, or FFL, were originally designed using tin foil and baking paper. Since then, it's been fine-tuned using layers of flexible laminates, but they're still about the size of a standard piece of paper.
FLL is similar to Electro-static speakers which have been around for years, but these are more efficient, smaller, lighter, and flexible. So, they can be used in advertising with audio posters, wrapped around corners, mounted in a car's ceiling, or hidden behind a painting.This technology operates at approximately 10% of the power consumption of conventional loudspeakers.

2. The Personal 3D Viewer

1: the Personal 3D Viewer from Sony can pick up from the apparent fall off in interest for 3D TVs, as it provides you with your own personal, immersive, cinema experience.The HMZ-T1 head mounted display features dual OLED screens that provide HD quality viewing, and integrated headphones to deliver virtual 5.1 surround sound. It’s claimed to be equivalent to watching a film on a 700 inch cinema screen.The display can be connected to a PlayStation 3 for high definition 2D and 3D gaming or a blu-ray disc player for a unique cinematic experience.The display can be connected to a PlayStation 3 for high definition 2D and 3D gaming or a blu-ray disc player for a unique cinematic experience.

3. Talking paper

Researchers from Mid Sweden University have constructed an interactive paper billboard that emits recorded sound in response to a user's touch.

The prototype display uses conductive inks, which are sensitive to pressure, and printed speakers.

The team envisages that the technology could be used by advertisers, and in the future, it might even be employed for product packaging.


Believe it or not, a 3D printer that uses chocolate has been developed by University of Exeter researchers - and it prints layers of chocolate instead of ink or plastic.

Although still a prototype, several retailers have already expressed interest in taking on the device.

3D printing using plastic and metal is already widely used in industry to speed up design work.

5. Unphotocopying

The process involves using short laser pulses to erase words and images by heating the printed material to the point that they vaporise.

The researchers say it works with commonly used papers and toner inks and is more eco-friendly than recycling

"When you fire the laser, it hits the thin toner layer and heats it up until the point that you vaporise it," the team's lead author, David Leal-Ayala told the BBC.

"Toner is mostly composed of carbon and a plastic polymer. It's the polymer in the toner that is vaporised.
