Journal Entry #8 – Proposal

The device I like to choose and talk about, is the virtual keyboard. This tiny device uses laser to project a keyboard on any flat surface. You can then type away accompanied by simulated key click sounds .Laser Virtual Keyboard can approach typing speeds of a standard keyboard and is the size of a matchbook. Below are some key points about this gadget. It actually looks pretty cool too. It
• Projects a full-size laser keyboard onto any flat surface
• Allows the convenience of full-size typing in a tiny form factor
• Connects wirelessly via bluetooth to iPhone, iPad, many Smartphones and most Laptops
• Mouse mode allows you to use your finger as a mouse rather than typing when using with a laptop.
• Rechargeable battery lasts for 150 minutes of continuous typing
• Charges via USB. No drive to install
The controller functions for the laser keyboard is very simple. I listed below what each represent on the cube.
