3. Accuracy And Typing Experience

On a normal keyboard I clock in around 80 wpm with a decent accuracy rate, while my speed with the VKB dropped dramatically. I got tons of errors/phantom clicks and spaces that didn’t register. When I first got the assignment, I thought a neat test would be to type the entire article on the VKB. However, this proved to be impractical. My problems with error rates made the VKB relatively unusable. Instead, I’d rather use the onscreen touchpad or thumb board, both of which pale in comparison to typical data entry rates with conventional keyboards.

Playing with the sensitivity settings was frustrating; adjusting them too low meant key presses, such as spaces, weren’t registered. Adjusting them too high resulted in garbage/phantom characters that were dumped in the document.

The VKB projects a QWERTY interface but users will find some of the keys are in the wrong place. This requires modification of one’s typing style to suit the projection/setup. Tactile feedback a user receives from a typical keyboard is absent and takes some getting used to. At times I would find myself on the wrong keys and would have to look down in order to get the proper mount back. My typing did improve after spending some time with the unit but I found I had to constantly go back, edit and correct entries.

In an outdoor setting the projection is nearly invisible; a classroom setting is more manageable but well-lit areas can be problematic, even with the keyboard’s brightest setting. Projection at night is clear, defined and bright.
