LightIO Touchless Keyboard User Instruction
This touchless keyboard utilizes infrared light beam detection technology to avoid pushing down key buttons on a keyboard. As seen in the above photo, each key area is surrounded by walls. Each wall has a slit to let a light beam pass. Two light beams cross above each label. When an opaque object, such as a finger or a pencil head, is put inside a cell and blocks both light beams, a key-down signal is triggered. When the object leaves and unblock the light beams, a key-up signal is generated. This keyboard has all the keys and can perform all the functions that a standard keyboard has.
When the light beam passing a row is blocked, the left LED lights up. When the light beam passing a column is blocked, the right LED lights up. A key stroke is generated only when both LED light up.
Plug and play for the first time:
When you plug this keyboard into a Windows computer, the computer will search for Windows Update for driver. Just click on the "Skip..." link and the default driver will load. No need to find any other driver to install.
When you plug this keyboard into a Mac computer, there is usually a message box asking for identying the keyboard by pressing the RIGHT Shift key. But when you trigger the Shift key on the right-hand side, sometimes the message box doesn't disappear. However, just wait several minutes and computer will take inputs from this keyboard.
To connect a USB keyboard to the iPad you must have the Camera Connection Kit accessory. The Camera Connection Kit adapters plug into the Apple 30-pin dock connector port. One of the adapters has a USB port that is officially advertised as a way to connect your digital camera directly to the iPad. It as been tested that connecting this USB keyboard to the adapter works.
It is observed that on about half of the computers this keyboard is plugged in for the first time, the Caps LED is turned on and seems reversed with the letters typed. But it becomes normal when the computer restarts.
