Frog pad
From Wikipedia, the free encyclopedia
A FrogPad is type of keyboard developed to be used with only one hand, similar to a Chorded keyboard. As a result, it is not a qwerty or azerty keyboard; it requires one finger to type approximately 85% of average data in English. No more than 2 fingers (opposable thumb and one finger) are required simultaneously for the remainder of data entry. The founder of the company is Linda Marroquin.
