Wireless Bluetooth Laser Projection Keyboard India 2021

A keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a surface when a user touches the surface covered by an image of a key, the device records the corresponding keystroke. Projection Keyboard connect to Bluetooth devices, including many of the latest smartphone, tablet, and mini-PC devices with Android, iOS or Windows operating system.

An Wireless Bluetooth Laser Projection optical virtual keyboard was invented and patented by IBM engineers in 1992. It optically detects and analyses human hand and finger motions and interprets them as operations on a physically non-existent input device like a surface with painted or projected keys.

In that way it can emulate unlimited types of manually operated input devices (such as a mouse, keyboard, and other devices). Mechanical input units can be replaced by such virtual devices, potentially optimized for a specific application and for the user’s physiology, maintaining speed, simplicity and unambiguity of manual data input.

In 2002, start-up company Canesta developed a Wireless Bluetooth Laser Projection keyboard using their proprietary “electronic perception technology.” The company subsequently licensed the technology to Celluon of Korea.

A proposed system it is called the P-ISM combines the technology with the small video projector to create a portable computer the size of a fountain pen.

A laser or beamer projects visible virtual keyboard onto level surface. It is a modern input device. A sensor or camera in the projector picks up finger movements. Software converts the coordinates to identify actions or characters.

Some devices project a second (invisible infrared) beam above the virtual keyboard. The user’s finger makes a keystroke on the virtual keyboard.

This breaks the infrared beam and reflects light back to the projector. The reflected beam passes through an infrared filter to the camera.

The camera photographs the angle of incoming infrared light. The sensor chip determines where infrared beam was broken. Software determines the action or character to be generated.

The projection is realized in four main steps and via three modules: projection module, sensor module and illumination module.

The main devices and technologies used to project the image are a diffractive optical element, red laser diode, CMOS sensor chip and an infrared (IR) laser diode.

Connectivity Projection keyboards connect to the computer either through Bluetooth or USB.

Bluetooth dongle technology enables the projection keyboard for point to multi-point connectivity with other Bluetooth devices, such as PCs, PDAs and mobile phone.

The way that Bluetooth projection keyboards connect to devices depends on the specific tablet, phone or computer.

Use the revolutionary new laser virtual keyboard and complete your daily computing activities in an efficient manner.
