    This semester, we are sitting in a strange bubble at home. No casual coffee with your friend between the lectures, no physical exchange of cool weaving trick to speed up your assignment, no hugging, no kissing… Instead of crying over all the things we lack, we can try to use the situation positively, as a unique experience of being isolated, connected only (or mostly) via internet with your friends and colleagues, but somehow share the experience together. Perhaps this is a chance to think about how we can design such an online, remote, yet connected experience. This is my proposal for this semester.

    Instead of treating each conductive petal contact of the this fabric tilt sensor as an individual digital input, the petals are connected through a resistive fabric ring. The end petals in this “resistor ladder” connectto GND and VCC to create a voltage divider (just like inside a potentiometer) and the bead makes for a voltage […]
