Phase VI Space Glove: Heater Switch Redesign

In collaboration with NASA TCC Wearable Workshop and the University of Minnesota, I worked on a team to redesign a critical component of the Phase VI Extravehicular Mobility Unit (EMU) spacesuit glove: the heater switch. The challenge was to develop a reliable, intuitive switch that could activate and indicate glove heating, while functioning in extreme temperatures and under the physical constraints of pressurized gloves. Through in depth research, user centered testing, and iterative prototyping, we explored ways to enhance astronaut usability in some of the most difficult conditions.
