An analysis of motor performance and users’ expertise”. Like other pointing devices such as mice , touchpads or trackballs , operating system software translates manipulation of the device into movements of the pointer or cursor on the monitor. And, in that design, they taper way off the edges. Pointing sticks were the dominant pointing device for laptops before the advent of the touchpad. Various informal names have been invented, including “nipple mouse”, [20] [21] ” clit mouse” [20] [21] and “nub”. IBM sold a mouse with a pointing stick in the location where a scroll wheel is common now. Unlike the American 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.

Joe learned Basic easily. Better manufacturing processes and jigs simplified the product too. Hmmm, somehow it was hard to control; we fiddled with feedback resistors and capacitors trying to create transfer functions to make good pointing… yuk…. We always hoped that a driver would make the cursors optimize for the purposes they needed the cursor for- this hasn’t happened yet.

It is also a story that Thibkpad would rather you hear from the person who told it to me, Ted Selker, the person mainly behind the trafkpoint. The night before the presentation, we fit it together in its final form: This made calibration impossible.


Others at IBM trafkpoint started using our micromanipulation technique. It still has this mysterious quality to the outside. This page was last edited on 14 Novemberat Ashok ordered us to be extravagant and make John Cock and 96 other interesting people hand-made pointing stick adorned keyboards.

Touchpad vs. Trackpoint

He looked at me gravely, let the moment stretch and then said, “Get two”. Grrr- it hurt and there was a dent in my finger when I used it. It may have life in the future, but at the time it ib, very experimental and added a lot of thickness and such. We made a ground that the piezoelectric devices would touch whe n the key was not pressed….

This was the next cool thing. He liked it- but then, a few weeks later he had a stroke. Personally, I thought that product was kind of cool. The touchpad wins, for me, because it’s such a simple input method — yet it supports some complex, subtle nuances that are surprisingly intuitive: We were happy, so we tried others using it. They might make some mistakes. Many months later, when we were using it in Trckpoint applications on my lovely Lisp machine I finally realized that the “turbo charge” part allowed me to toss the cursor across the screen …to change window context.

How to handle notebook input devices: So, you can type and move the cursor without doing this [mimes a hand shifting between a keyboard and a trackpad].

I recently switched to a work-provided Thinkpad T40 as my primary laptop, and it has both trackpoint and touchpad– great for an apples-to-apples comparison. We wanted to get the PCcompany to see our in-keyboard pointing device. It was also incredibly efficient, as everything that goes into a laptop is generally square.


We need to talk about the nipple mouse

But, if they ever want to make a computer with very narrow borders, they will have to be square. IBM sold a mouse with a pointing stick in the location where a scroll wheel is common now. Picking up one of these expensive silicon gauges by its gold leads broke it. When thinkpa strain gauge was in place, the superglue came out. If you’re looking for an empirical way to prove the superiority of one input method over the other, good luck.

Each of these features is a story in iteself. All EliteBooks excluding series; all models ending with p or w ; all models starting with ncnw or c ; b optionalb optionaltc, tc; Presario models starting with v A pointing stick can be used by pushing with the fingers in the general direction the trackpkint wants the cursor to move.
