A typical solution, which assumes that pointing sticks frequently go out of calibration, is to interpret a variation below a certain threshold over a given interval, perhaps one or several seconds as being a neutral stick. We wanted to get the PCcompany to see our in-keyboard pointing device. The keyboard, if you recall, lifted up [to reveal] all of the components inside — like a bento box. Bill – let me tell you a little story about Trackpoint! So now we built a graphical interface for designing a transfer function that went through arbitrarily drawn places in the force-to-velocity space.

This is because a user’s finger may run off the edge of a touchpad while positioning the pointer, requiring them to reposition their finger in order to continue. Yamada-san stood up and gave a 45 minute talk about one cell on the learning curve matrix, the only one that showed the pointing stick being worse than a trackpad or trackball,for the first 15 selections.
Yes, I s jbm want to do it NOW.

Piezioelectrics are not at all good for DC analog measurement. It would overshoot and you had to move it slowly back to where you meant to stop. Ashok Chandra sat me down to help me integrate the data from seemly inconsistent experiments done at various labs in the world. We built one for him anyway that bent and brought it to Japan.
The joystick for this had no deadband, it had an exquisite sensitivity and control … we never made an inkeyboard device that shipped with this thnikpad set of algorithms and scenario.
Grrr- it hurt and there was a dent in my finger when I used it. It seems some people used tendon flex to improve pointing- we found this looked like overshoot and we had trouble making the adaptive algorithms stable in the time thinkpzd we gave it.
We fiddled and fiddled – after a short time though we discovered a weird thing. This entire post, including the image editing, was performed with the touchpad. This was the next cool thing.
The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. Also, at the time, it was a nice contrast to the stark geometry of this box. Bob Olyha worked on circuitry- improving everything about stability and calibration trackponit many other things. We made a special application that was a game people played to improve their pointing —as their game play improved the transfer function improved too!
Trackpojnt has that curve at the bottom edge that actually makes it less likely to make a typing error. This page was last edited tracjpoint 14 Novemberat He was fascinated by this concept that an object was simple when you were not using it and complex when you were. I now easily taught a brilliant Joe with a photographic memory digital electronics. Others at IBM research started using our micromanipulation technique.

Product manager and man with deep insight Ikeda and top engineer Trafkpoint Naito both hated the way it felt- Ikeada pushed down hard and showed me how it left a dent in his finger. As soon as we showed the trackpoinf in Cambridge, England at Interact it was obvious it was a great hit.
I did a preliminary study that showed how novices selected faster with it; the product group saw no need to spend the money for that.
Well, they can do that because they have such a huge border. One criticism is that because the pointing stick depends on the user’s applying ihm, it can cause hand cramps although this can be partly solved by setting the sensitivity higher and lifting the finger when the pointer is not being moved.

For the teaching and presentation aid, see Pointer rod. User specific requirements for input devices and software design” PDF. Additionally, if “press-to-select” is enabled, the software may generate unexpected click events trckpoint touching the pointing stick during typing.
If I go back and think about IBM, and its commercial desktop business, one time they said they would never sell a color monitor — wrong. The distinguishing trackpoitn, however was the team approach to decisions and execution throughout the IBM Japan culture, a direct contrast to the processes we had encountered in the US IBM PC groups in the early s.
