=== Laser projection ===
{{Main|Projection keyboard}}

A laser projection device approximately the size of a computer mouse projects the outline of keyboard keys onto a flat surface, such as a table or desk. This type of keyboard is portable enough to be easily used with [[Personal digital assistant|PDA]]s and cellphones, and many models have retractable cords and wireless capabilities. However, this design is prone to error, as accidental disruption of the laser will generate unwanted keystrokes. This type of keyboard's inherent lack of tactile feedback makes it often undesirable.
