Prevalent Devices LLC Announces World's First Robotic Hand to Successfully Demonstrate Texting Using Phraze-It Digital Texting (PIDT)

Prevalent Devices LLC announced that its one-handed PIDT gestural code was successfully demonstrated by a texting robotic hand. The one-handed gestural texting method for simplified texting joins the Phraze-It on-screen keyboard for typing with fingers on large touch screen keys of Windows Mobile devices.

Prevalent Devices LLC announced the world's first successful demonstration of a robotic hand communicating utilizing the company's gestural alphabet called Phraze-It® Digital Texting (PIDT). The demonstration took place at Cal Poly with a robotic hand created by Mario Garcia and Professor Saeed Niku Ph.D. The project was supported by the Smith Kettlewell Eye Research Institute. Videos of the texting robotic hand are available online at youtube.com.

Created to explore ways of communicating in both ASL Fingerspelling and in PIDT, the robotic hand achieved easy readability in PIDT. The approach is to provide both immediate tactile communication by placing the human hand so as to be in contact with the robotic hand, as well as providing visual communication via readable hand gestures. Fewer lines of code are required to program in PIDT compared with programming for ASL Fingerspelling.

Phraze-It® Digital Texting (PIDT) is a patented simple gestural texting method based on leveraging the familiarity of the five vowels A, E, I, O, and U to simplify the task of texting by hand. In the PIDT gestural alphabet, each vowel is the lead character in a vowel set comprised of that vowel and the consonants immediately following in the alphabet. For example the A is the lead vowel for A, B, C and D. The E is the lead vowel for E, F, G and H. PIDT enables simplified text messaging with one hand.

PIDT assigns the vowel 'A' to the thumb, the 'E' to the index finger, the 'I' to the middle finger, the 'O' to the ring finger and the 'U' to the little finger.

The first gesture of the systematic PIDT code is to bend any one of the thumb, index finger, middle finger, ring finger or little finger to indicate one of the vowels A, E, I, O or U respectively.

The second PIDT gesture to text a vowel is to bend all the fingers- called the Common Gesture. The second PIDT gesture for texting a consonant is to bend the thumb, index finger, middle finger, ring finger or little finger associated respectively with the first, second, third, fourth or fifth consonant following the vowel that precedes such consonant. To illustrate the word 'hello' in PIDT:

First Gesture: Bend            Second Gesture: Bend            Letter
Vowel: E    Index Finger        Letter H    Middle Finger        H
Vowel: E    Index Finger         Letter E     Common Gesture    E
Vowel: I    Middle Finger        Letter L    Middle Finger        L
Vowel: I    Middle Finger        Letter L    Middle Finger        L
Vowel: O     Ring Finger         Letter O     Common Gesture    O

PIDT is a simplified method of one-handed texting also for electronic gloves and virtual environments.
