I once worked in Tek for a very short period. I got to experience the 2235 and 2465 analog scopes and their controls. The 2465 was a 400 MHz Digitally Controlled Analog Scope.
I also used the Plugin System Scopes and Calibration systems; these were Tek Culture and Tech contribution to the Instrumentation world, it probably evolved into VXI-PXI as uC systems took over.
I also had a chance to look at DSO/Logic Analyzers and the just developed TDS Series. The older tek analog scopes made me understand about usability and panel layouts. Many controls are inevitable in a Analog Scope with Electromechanical Interface.
In a Digital World that can be largely changed using the Monitor and Trackballs. The older BlackBerry phones are also good study for usability before Touch Screens came.
delabs Web Widget and Application Interface Usability Experiments 2003-2008
In 2003 i tried some experiments in Web Interface. I also converted some mini DHTML Widgets i made in 2000. These i later added to iGoogle too. In 2000 it was a Midi Player later an Alarm Clock when iGoogle came. Then a Metronome and Mini-Notes Holder and a Text-Database driven Music Player.
Talking of Touch Screen, i had seen a Monitor in a Universal Pick-Place Assembly Machine. A Huge Pneumatic System, Not a SMT, there was no SMT then. This monitor had IR LED and Opto Transistor Array over the monitor. That sensed the finger Probably.
Capacitive Touch Screens and Accelerometers have given a new dimension to Ergonomics.
Then came Euro controls for Consumer Electronics. Like remote controls. Look at the National Panasonic VCR Remote on the right. It could be in the 90's. It is so easy to operate the VCR, you do not need a manual. Flap a Lid and you have many things to do, including control any brand of TV in tandem with the VCR.
Software or hardware it is the same thing. The way the Common man sees a Gadget, like a Lamp Switch or a Water Tap.
The HTML5 thing also is in the same direction, which empowers Web Designers to make Usable Apps and Sites not just Flashy Mazes where one can get lost for eternity. Some of the sites i built are like that, Labyrinth of Docs which only the Search can Reveal.
