Hello Ken:
I posed the questions as examples of design decisions. However, if anybody has suggestions in that regard I certainly welcome them. Often the eyes of a less interested person have clearer vision from afar than my vision which is too narrowly focused by intense interest in the problem closely at hand. As for that 4x20 display with 3 pushbuttons, it certainly is a minimalist user interface. Obviously MicroSoft had no part in its design ;] Keeper of the Primordial Bit (born of the Big Bit Bang), -= Ron Wiesen =- _____ From: M100 [mailto:[email protected]] On Behalf Of Ken Pettit Sent: Friday, October 23, 2015 18:03 To: Model 100 Discussion Subject: Re: [M100] Program Design is Greatly Influenced by Small Screen of Model T Laptop -- WAS RE: Rasberry PI inside a TRS 80 Model 100 On Fri, Oct 23, 2015 at 10:45 AM, Marko Peussa <[email protected]> wrote: User interface design for small screens is a big topic. Especially for text screens. Unfortunately, I haven't seen much material on it. In factory automation one has to deal with screens a lot smaller than 8x40. And the available keys are usually: four directional buttons, an 'OK' and and 'ESC'. Indeed. I had to make improvements and additions to an automation system with a 4x20 display and only 3 pushbuttons. The company still contacts me ocassionally for minor changes / upgrades to the firmware. Ron, in your original post regarding the preferred method of reporting for the unit of measure, were you posing the questions as simple examples of the design decisions that must be made, or were you looking for feedback from the group regarding the approach you should implement?
