Structured interactivity

I have had long thought sessions about how to make my LED creations interactive. Toying with sensors, buttons, sliders etc… has often wielded “meh” results. In the end, a web/app based approach will probably be best. But how do i make it un-boring? The idea of the Idle render, what is rendered when no interactivity is around, is very important. I had an idea last night about a structured render algorithm that could be made to create really interesting patterns and be structurally interactive.

Most of my render algorithms are very similar, varying slightly in certain ways:

  • Create a color object using an index value starting at 0 ending at “6 x Maximum value of Each LED”
  • Create an X and Y coordinate using either a random number bound to the LED map, or a certain pattern
  • Apply color to a pixel, line, box or circle at X Y co-ordinates
  • render
  • add a delay of d milliseconds
  • apply a canvas shift function of some sort
  • apply a canvas fade function with a fade value f
  • repeat

The above creates some amazingly diverse animations. I plan to write up a simple web interface that allows you to control each step and then send the updates to the MU via wifi.

Here is a rough draft of a web app:


This sends a POST data packet at each change in the interface that looks like this:
