Join The–Dots


Ever had a doh! moment?, that is the moment when the door slams behind and you slap your forehead realising you left the house without taking the keys.This device is the response to that “thoughtless act”, that daily ritual everybody performs to remember not to forget.

As one of the assignments in Sydney Uni's Master in Interaction Design the brief was observing "thoughtless acts" in everyday routines and try to find a chance for innovation to then design and prototype a device that would assist in people's daily lives.

One of most common ways to remember items is by binding them to a physical location. The concept behind this device is to virtually link items to one significative location: the knob of the exit door.
The device will recognise previously tagged objects and rise an alert with one is missing, identifying the type of item by a color code.

This was a solo project, from concept to assembling the electronics and programming the microcontrollers. Including the filming and edition of the promotional video and the design of logos and poster.

The device was featured in Engadget(US), Amnesia Razorfish (Australia) and Tecmundo (Brazil) technology blogs among others. It's promotional video hosted in Vimeo has overpassed the 4.5k visits to the date.

Work on display in Attract::Relate::Sustain exhibition at The Verge, Sydney.

This assignment was marked with high distinction.
