A 5-week exercise in empathy and interaction design through the lens of consumer tech that:
Solves a simple problem using programmed Arduino sensors and light effects
Supports and conceals all electronic components
Is conceptually demonstrated by a working prototype
This project required me to be mindful of the size and position of sensors and a microcontroller in my design. Taking on an engineer’s perspective will help me work with them in the future.
Objective
The problem of the missing TV remote was appealing to solve because it turns a relaxing activity stressful. The device would need to detect the Roku remote (popular, easy-to-lose), detect whether or not the TV is on, and signal the user to return the remote using light effects.
Problem
Inspiration
Visually successful minimalist tech, including the Roku remote, is usually comprised of subtle curved surfaces. Organic forms with unique silhouettes are both eye-catching and approachable. Additionally, bottom heavy forms appear safe places to rest fragile devices.
Ideating
Early rectilinear concepts were simplistic and bulky. Some concepts were clearly not accommodating of the necessary hardware: An Arduino Nano, breadboard, photoresistor, IR sensor, and LED strip. Cylindrical forms with angled faces, however, allowed building up and put the demote on display.
Refining
Later, bulky concepts were enhanced with negative space and dimples, but cylindrical forms made dynamic with exaggerated angles and protrusions remained strongest. Front lighting turned out to be most practical for catching user’s attention, and representing where the remote should go.
3D
The first CAD model was thick and overpowering, softened by a tapered back and rounded bottom. Later, hardware supports were incorporated, and repeatedly altered for fit. Remote cutout depth was at times so deep it was hard to grasp the remote or so shallow the remote was not secure. This was addressed in the final iteration.
Finishing Up
The high fidelity model, which followed multiple mid-fidelity iterations, is spray painted black and programmed to emit purple light to match the Roku aesthetic. It is fully functional, containing a soldered circuit programmed with the help of Claude and ChatGPT.
