This is a pocket-sized projector that beams a full-size QWERTY keyboard onto any flat surface and pairs over Bluetooth with phones, tablets, computers and laptops. It adds a built-in display that shows key presses in real time and simulated key-click sound feedback, and some bundles pair it with a projection mouse or a Bluetooth speaker. It suits travelers, minimalists and gadget fans who want to type on a real layout without carrying a keyboard. Against folding Bluetooth keyboards it wins on portability but loses on typing feel, speed and battery life, and owners of similar laser keyboards report a real learning curve and misreads on uneven or bright surfaces.

This device projects a full-size English QWERTY keyboard onto almost any flat surface. It connects over Bluetooth to most Bluetooth-enabled devices, including computers and laptops, so you can type emails and other text without a physical keyboard.
A built-in display screen shows your key presses in real time. Simulated keyboard sounds give audio feedback as you type. The projected keyboard is meant to approach the typing speed of a standard keyboard, and the device is no larger than a matchbook, so it fits in a pocket.
Some versions include a Bluetooth speaker.
