Bluetooth virtual projection keyboard, also known as a laser keyboard, is an innovative device that projects a full-sized keyboard layout onto any flat surface, allowing users to type without a physical keyboard. This technology utilizes infrared light to detect keystrokes, providing a unique typing experience.
Key Features
Wireless Connectivity: The keyboard connects to various devices, including smartphones, tablets, and laptops, via Bluetooth, offering users freedom from traditional wired connections.
Compact Design: Lightweight and portable, these keyboards can easily fit into a bag or pocket, making them ideal for on-the-go use.
Laser Projection: The device projects a standard QWERTY keyboard layout onto a flat surface, enabling users to type directly on the projected image. This projection is created using a keyboard pattern projector and infrared light.
Typing Recognition: When a user presses a key on the projected keyboard, the infrared light beam is interrupted, allowing the device's sensors to register the keystroke. This system tracks finger movements in three dimensions, enhancing typing accuracy.
Multi-Functionality: Many models also offer a mouse mode, allowing users to control the cursor and perform actions like clicking and scrolling by tapping on the surface.
Rechargeable Battery: Most virtual projection keyboards come with a rechargeable battery, providing several hours of use on a single charge.
