Additionally, if “press-to-select” is enabled, the software may generate unexpected click events by touching the pointing stick during typing. At the last moment, the lawyer relented and helped me submit the paperwork correctly. To bolster confidence in our judgment, human factors experiments were run in Austin, Boca, Lexington and Yamato. He went home and told his boss Bob Lawton that they should consider this device for the L40SX computer. A lot of the touchpad’s functionality is dependent on the software drivers. Wow was this weird… we discovered you could only hold the finger in the circle with like 5 or so bits of resolution. Retrieved from ” https:

We tried various transfer functions: We worked on it on the side to begin with… in If the user releases pressure at this point, the change will be interpreted as an instruction to move the opposite direction.

Just like others’ joystick experiences, it skated over the material but when you wanted to stop you couldn’t. But scrolling is out of the question, of course.

We need to talk about the nipple mouse – Hacker Noon

An inplane joystick invention made the post more robust in several ways. At no point was I frustrated or rate-limited by the touchpad. I trsckpoint about thinking of places to put a pointing device that the hand could nab from the home row position… I tried in front of the keyboard … and yes made a mechanical claptrap that year that had X and Y excursion to do this.


So now we built a graphical interface for designing a transfer function that went through arbitrarily drawn places in the force-to-velocity space.

When the strain gauge was in place, the superglue came out. This I hate to say was the beginning of a 9 month long list of tiny successes. The people in Austin, Lexington and Boca seemed disorganized around our innovation. But choice is good, I suppose. Which renders the whole touchpad vs.

Product manager and man with deep insight Ikeda and top engineer Arisama Naito both hated the way it felt- Ikeada pushed down hard and showed me how it left a dent in his finger.

At that point the clay mounted to the desk and pressing it tgackpoint to the sensor moved it towards a strain beam it could be mounted on.

Pointing stick

Another challenge with pointing stick design is identification of the zero position the position where no motion is desired. As soon as we showed the device thinpad Cambridge, England at Interact it was obvious it was a great hit.

ThinkPads have a prominent middle mouse button, but some models have no physical buttons. They improved novice performance and were loved by the special needs community.


Touchpad vs. Trackpoint

I got up and pointed out to everyone’s amazement that while the Japanese’s data was the most carefully taken and cleanest ever produced, it all represented a user’s first experience only: We had to replace the large Measurement System’s joystick package.

Unlike the Trackpolnt decision process, everyone in that meeting went to the next level up meeting and we were required in an embarrassing show to repeat our conflicting talks again.

A Dynamic Pointing Function”. I’m a touchpad man, myself. Jim Lewis ran excellent experiments. From Wikipedia, the free encyclopedia. And, the dual-screen thing I thought was very useful. I reminded them of my “bet my badge” deadline as the time approached.

A Conversation with Ted Selker Interactions. We had believed there was no space between keys for such motion.

The mouse buttons can be operated right-handed or left-handed due to their placement below the keyboard along the centerline. Others at IBM research started using our micromanipulation technique. At that time a thinmpad at Stanford started trying to prototype it based on my ideas but it was time to go off to Atari.
