A-Tire is an automated wardrobe system designed to be used by people who have upper mobility issues, specifically those who have difficulty reaching above shoulder height and below the waistline. The shelf will be at a comfortable height for the user so that they do not need to apply more stress to their aching joints. Its design is similar those to a round drying rack people use to store their clothing. The user uses a cube to select the shelf by colour. Six shelves are coloured to coordinated with the cube’s faces to aid in selection. The colour facing upwards determines the shelf shown. In circumstances where power is unavailable, which is indicated via LED, a treadle enables manual interaction.

A-Tire was created within a month’s time and was for the Physical and Tangible HCI class at the University of Calgary. This project was developed with Michael Hung, Licelot Arias, and Nicole Laursen. A-Tire is powered by an Arduino Mega 2560 and uses a Grove IMU 10DOF (which contains an accelerometer, gyrometer, and magnetometer) in the primary input component, a force-sensitive resistor that helps simulate mechanical input via treadle in sans-power circumstances, a button to switch between powered and sans-power modes, an LED that turns on when in sans-power mode, and a 180 degree servo motor drives the motion of the drum. We used foam board, styrofoam, mini popsicle sticks, skewers, and cardboard to construct our prototype.
