The Doodle Daydream is a collaborative LED grid display that is embedded into the office architecture to encourage playful interactions.

Illustration of the four steps in the interaction flow. First step is to connect to the web app from a mobile device or laptop. Second step is to select a desired colour from the drop-down palette. Third step is the draw the design. Fourth step is to see the design displayed on the Doodle Daydream display.
Interaction flow

It displays drawings sent from with a mobile web application interface which acts similarly to a shared sketch pad. Users contribute their own custom drawings that immediately play back on the display, fostering moment-to-moment playful interactions.

In collaboration with Samitha Elvitigala and Noura Howell, I assisted in:

  • Designing and fabricating the display panel and assembly
  • Recording and editing the video
  • Running the user testing of the system and making the poster that was presented in SUI 2018.

The display panel was designed such that the LED modules (Philips iColor Flex LMX RGB LED) could be press-fitted into the laser-cut acrylic panel that was 1.3 by 0.9 meters. Modules were arranged in an isometric grid (0.05 meters centre-to-centre) which made the display seem to have higher resolution and allowed for more natural-looking drawings. The display assembly was also press-fitted into a window sill at an office space.

The LED modules are encased in plastic cylindrical cases.
