now, there's navigation panel on the left.
new index page.
ah, smell the sweet history of trackball.
for history's sake, here's
another dead endeavor
lots research on trackball in past days. They are not dying.
list of Trackballs with Scroll Wheel
old one, new page.
another update today.
this one, is a 3D mouse.
as far as design goes, this one is basically a 4-way joystick, plus up/down sensor, and twist clockwise/anti-clockwise sensor, and a non-tilting NSEW 4-way push sensor.
all in all, it actually is inferior to a design based on trackball or mouse, because, as a joystick, it does not have any instantaneous variable speed capabilities, such as in a mouse or trackball or touchpad.
a better design, would be starting with a trackball, then add up/down sensor, and twist clockwise/anti-clockwise sensor, and a non-tilting NSEW 4-way push sensor.
but, if that, still not good because these added movement doesn't have instantaneous variable speed.
so, a even better design is to 1 trackball, 1 joystick, and another one, may be trackball or joystick. The joystick will be used as 8-way control without instantaneous variable speed. For some movement, it's better that way.
but the problem is that now you have multiple parts that you need to hold, as if needing 2 hands operation.
what is instantaneous variable speed?
first, know that there's continuous change of position (mouse) vs instantaneous jump to position (pen tablet)
instantaneous variable speed is like mouse. A joystick is not. It has constant speed. But some joystick has variable speed, depending how far you push it in one direction. But still, the speed change is not random instantaneous variable.
lots mouse update in a day. This one, has a updated version with 1 extra button, and also has left hand version. Also, there's now a video review.
