Given the subjective experience of pain, self-report is considered essential to its measurement and, in turn, treatment. Through user-centered design approaches, lab studies, and field trials, this research develops novel interfaces and tangible devices that support accurate, quick, and repeated use along with other participant-valued interactions (e.g., discreet, intuitive, highly manipulable).

Key tools developed in this research include:

• Keppi: A pressure-based tangible user interface for pain self-report, designed as a wearable device with multiple form factors including necklace, bracelet, and keychain
• Meter: Novel smartphone-based pain assessment interfaces that support tailored momentary self-assessments for chronic pain management

Emerging directions in this work explore circadian rhythms of pain and cancer pain experiences, including collaborations on pain management for cancer survivors.
