To assist people in practicing mindful breathing and regulate their perceived workload while not disturbing the ongoing foreground task during daily routines, we developed a mobile and personalizable pneumatic-haptic feedback device that provides programmable subtle tactile feedback. The device consists of three soft inflatable actuators embedded w...

This work investigates the structure and mechanical properties of a textile-like material fabricated from polylactic acid (PLA) filament in a fused deposition modeling 3D printing process. Fused deposition modeling has expanded access to 3D printing, but the resultant parts are largely limited to rigid forms. The process characterized in this work...

Microbe-HCI is a community whose works implicate micro-organisms in HCI. This special interest group is a venue for the first gathering of the community, offering an opportunity for networking and structured discussions. It encourages participation from both active and new researchers to microbe-HCI, with the objective of acquiring an overview of p...
Conference Paper
This work introduces “destaining” as an interactive component for the HCI community. While staining happens unintentionally (e.g., spilling coffee), destaining can be used as an intentional design tool that selectively degrades stains on textiles. We explore the design space using silver doped titanium dioxide (TiO2/Ag), stains and light as a set o...

The home is a place of shelter, a place for family, and for separation from other parts of life, such as work. Global challenges, the most pressing of which are currently the COVID-19 pandemic and climate change have forced extra roles into many homes and will continue to do so in the future. Biodesign integrates living organisms into designed solu...

Conference Paper
We present DefeXtiles, a rapid and low-cost technique to produce tulle-like fabrics on unmodified fused deposition modeling (FDM) printers. The under-extrusion of filament is a common cause of print failure, resulting in objects with periodic gap defects. In this paper, we demonstrate that these defects can be finely controlled to quickly print thi...
