Augmenting Ambient Contexts to Various Applications


Context awareness provides better understanding of user, which can be used in many different ways. I’ve explore augmenting ambient acoustic contexts to conversational agents to extend the capability of the existing smart speakers. I’ve also worked on non-textual communication application that recommends avatars that represent user’s current state so that users can simply select and tap to share their states with friends and family. Lastly, I’ve explored using users’ subtle motion to provide seamless content sharing experience across different devices

Understanding People’s Well-Being from Passively Sensed Data


Sleep is critical to human function, mediating factors like memory, mood, energy, and alertness. Although it is commonly conjectured that a good night’s sleep is important for job performance, this relationship has historically been hard to quantify due to the difficulty of capturing objective measures in real-world contexts. We have explored the relationship between sleep and job performance in the wild, and sleep and sleep tracking app. Also, we have also explored the feasiblity of using mobile app interaction time as an indicator of sleep behavior and job performance

Usable and Reliable Consumer-Facing Mobile Health Applications


There have been increasing number of mobile health applications available for general population. However, the usability and inproper guidance could result in suboptimal performance, if worse, misdiagnosis. To minimize human error in self-diagnosis using mobile phones, I have been building an smartphone application to guide users to perform the task correctly in real-time using computer vision techniques. I am also exploring a method to ensure sensor inputs (e.g., image, audio, accelerometer) are compatible for the machine learning models to perform at its best performance.
