Testimonials

Features and Comfort:
"No more monster on my desk... finally someone has integrated the keyboard and mouse into one hand. I wrote a 30,000 line program with the Twiddler in complete comfort"
Dave Oertel, Sr. Software Engineer

Stress:
"I no longer get physical fatigue or stress from having to maintain a constant body posture or hand position"
Will Howery

Mobility:
"I learned in one week. Now my 'workstation' is my recliner and a 17" monitor."
Joe Mumme, Electronics Technician

Product Review:
"Twiddling my way through work is an appealing alternative."
Byte Magazine Product Review

Ease of Use:
"I am an _extremely_ satisfied Twiddler user. I have recovered almost 100% from RSI since switching from the mouse and keyboard to the Twiddler. You seem to have saved my career. I recommend to others, often. I have become an ambidextrous twiddlerer giving one hand a complete rest for extended periods. I have "hotkeyed" java keywords to expediate programming. I was pleased when Handykey serviced and returned my Twiddler in days when it needed a tune-up." (Editor's note: RSI is a complex issue about which Handykey makes no claim of benefit. Mr. Orbanes recovery may have had nothing to do with Twiddler use.)
Julian Orbanes

Technology:
"You can be sitting in front of your computer, or standing away from it, or lying down for that matter, and the on-screen cursor follows the motion of your hand!"
New York Times

Wearables:
"Twiddler was one of the first components I bought when designing my wearable computer. After six years of everyday use, I wouldn't think of using a wearable without one. The convenience and ergonomic benefits become apparent with long-term use. In fact, for the last two years, the Twiddler and my wearable computer have replaced my desktop (e.g. my PhD thesis was written with the Twiddler).

When starting the MIT Wearable Computing Project, I issued every member a Twiddler as their primary text input device. With starting another group at Georgia Tech focused on wearable computing, I've just placed an order for 10 more Twiddler 1's. We've seen typing speeds of 60 words per minute, and an undergraduate has reported speeds up to 30 words a minute with only a weekend of practice. More generally, new users can learn the alphabet in 5 minutes and can be touch typing in an hour. Though it takes time for the fingers to "loosen up" to accomodate the new motion (much like learning to play an instrument or learning how to type on a desktop), many new users are up to 10 words a minute with a weekend's worth of practice, and current non-touch typists remark that it is easier than learning the desktop QWERTY keyboard.' "

"I'd like to say that I have been very happy with the Twiddler. I've been tinkering with wearable computers for some 15 years now, and never come across a better input device. I've designed and built a number of input devices from microswitches and the like -- before the Twiddler was being manufactured, but I really do like the Twiddler, despite its 1 or 2 shortcomings. It gives me the same sense of tactile feedback that I get from a high quality microswitch, enabling me to control various kinds of apparatus without my needing to pay full attention to the screen...If you need any ``testimonials'' from an experienced tinkerer, designer, builder, and user of wearable computing, I'd be happy to recommend Twiddler to wearable computer users, over and above voice (or certainly at least in addition to), eye movement trackers, and all of the other ways of controlling computers or external devices."
