"Immersion's VibeTonz system is the most exciting opportunity to improve the usability of touchscreens that I have ever experienced," said Scott Weiss, author of Handheld Usability and president of Usable Products, an ease-of-use agency focused on usability research and design of handheld products. "It has to be felt to be believed."

"Touch screen technology in phones is primarily aimed at high-end smart phones and PDAs at present. Touch screen cost reductions and the emergence of applications designed for touch screens will be critical for market growth. Also, the integration of any technology that enhances the user experience and improves ease of use will be important for market adoption," said Stuart Robinson, director of the Handset Component Technologies service at global research and consulting firm Strategy Analytics. "We believe that market conditions are almost ripe for an explosion in touch screen phones and that by 2012 as many as 40% of mobile phones could be using some form of touch sensitive technology."
