We explore how embedding a living organism (in this case a slime mold, Physarum Polycephalum) as a functional component of a device, changes the user-device relationship. In our design, the user needs to care for the living organism (through providing food and water) in order for the device to work. When healthy, the organism participates in the device’s functionality by acting as a physical wire that enables power to the watch’s heart rate sensor. As such, caring for the device is intrinsic to its interaction design —with the user’s care, the slime mold becomes conductive and enables the sensor; conversely, without care, the slime mold dries and disables the sensor, and resuming care resuscitates the slime mold.

2. Designing with Chemical Haptics.Jasmine Lu. Design Research Society Bilbao ’22.
Chemical receptors exist all throughout our body and are embedded throughout our skin. In this paper, I discuss my recent explorations in chemosensory interfaces for the skin and what possibilities it enables for the interaction design community. I outline my process of designing with these sensations, discuss how the chemical haptics approach induces uniquely complex sensations, and speculate on chemosensory design futures.

We propose a new class of haptic devices that provide haptic sensations by delivering liquid-stimulants to the user’s skin; we call this chemical haptics. Upon absorbing these stimulants, receptors in the user’s skin are chemically triggered, rendering distinct haptic sensations. We identified five chemicals that can render lasting haptic sensations: tingling (sanshool), numbing (lidocaine), stinging (cinnamaldehyde), warming (capsaicin), and cooling (menthol). To enable the application of our novel approach in a variety of settings (such as VR), we engineered a self-contained wearable that can be worn anywhere on the user’s skin (e.g., face, arms, legs).
