Ubiquitous Computing

glasstabletfitbitThe dream of ubiquitous computing is not so much that computers will be everywhere. That’s the shallow interpretation. It was actually about how we’re going to deal with a world where there are computers everywhere; that is why Mark Weiser (who many people call the father of ubicomp) pushed for making computing invisible-in-use.

As an undergrad, I heard Mark Weiser’s name mentioned every once in a while at lab group meetings. When I read more about him, I decided that I wanted to work at PARC, where “ubiquitous computing” was born. While at Stanford in grad school, I interned at PARC and spent several years reading through the Stanford library archives on Mark Weiser’s work. It inspired me to dig deeper into how we can make computers less demanding of our attention and make them fade into the background of everyday experiences.


With friends like Wendy Ju and Bjoern Hartmann, we took on projects to explore how we might use computation to design automatic doors to be more welcoming (right) and leverage embodied cognition philosophies to encourage interaction designs that take human embodied experience more seriously. This is why I push for robotics to become so (quietly) useful that they become unremarkable.

In 2017, I served as general co-chair along with Khai Truong and Claire Lee in hosting the ACM Ubiquitous Computing / ISWC conference.
