CORONA TOUCH: Touch activated light display

Introducing the “CORONA TOUCH” interactive light display.

Based on ongoing developments for the elderly and/or people with cognitive challenges, CORONA TOUCH is a touch-activated light machine that creates a wide range of beautifully animated and soothing light patterns that emanate from its core.

Here are a few movies (care of Shirley Lee) of the CORONA TOUCH in operation

According to Wikipedia, “A corona (Latin, ‘crown’) is an aura of plasma that surrounds the sun and other stars… ” noting that “… the high temperature of the Sun’s corona gives it unusual spectral features”.  This is fitting for this little machine, as everyone who has played with CORONA TOUCH has been enthralled and attracted by its vivid colours and animated patterns.

Shirley, a friend who is a recreation professional organizing activities and programs for seniors in long-term care, noted

“The smaller interactive light display [CORONA TOUCH] is a hit.  I tried it with 3 residents today.  Two were touching and changing the colors.  One resident was stroking and touching the smooth surface.  With another resident we had to hold the display up so he could see.  He needed prompting (hand-over-hand) to activate the lights.  He liked the pattern with the flashing multi-color patterns.”

Here are a few shots of the CORONA TOUCH that show off some of its amazing colour patterns. As they are all animated – some faster than others – forthcoming video may do it greater justice.

CORONA TOUCH is 120mm (nearly 5″) in diameter and 24mm (1″) thick and is packed with 60 LEDs arranged in 4 concentric rings. A touch sensor in the centre of the top surface allows the user to control both the intensity of the emanating light and the speed of its animation.

A second touch sensor on the bottom assembly works with the top sensor to allow the user to cycle through different light modes. There are currently 9 separate animation modes:

  1. Mode 1:               rainbow_loop(backwards)
  2. Mode 2:               rainbow_loop(forwards)
  3. Mode 3:               rainbow_rings
  4. Mode 4:               ring mode
  5. Mode 5:               gradient
  6. Mode 6 :              confetti: random colored speckles that blink in and fade smoothly
  7. Mode 7:               sinelon: a colored dot sweeping back and forth, with fading trails
  8. Mode 8:              juggle: eight colored dots, weaving in and out of sync with each other
  9. Mode 9:              spirals: colored stripes pulsing at a defined rate

Here are some more images of some of these modes in action (Photo credits: Shirley Lee)

The two-part clam-shell enclosure is designed in SketchUp and cut using my CNC machine. The two parts connect together with 4 recessed M3 machine screws and the only connection to the device is a 5.5mm 9V DC power socket. Internally, there is an Arduino Nano, two capacitive touch sensors, and the 4 concentric addressable LED rings (24, 16, 12 and 8 LEDs respectively). Power is supplied through a 5V step-down DC-DC invertor.

Standby for more images, video and explanation of its design and operation.

      John,
      I do… This is my design – electronics, software and CAD/CAM for the case.
      It is receiving lots of attention as the elderly and those clients with dementia love it… I plan on making more of this unit and building a larger version as well.
      Can I ask what your interest is?

      … Adrian
