Perceptual Augmentation Systems Lab
Machine-translated · View original
The lab augments human perception and the body using sound, VR/AR, and AI.
AboutAbout the lab
Bridging the gaps that individuals cannot close alone.
The Perceptual Augmentation Systems Lab studies technologies and systems that enable activity in a world where the boundaries between cyberspace and physical space, and between on-site and remote, are blurred.
The lab aims to bridge gaps that individuals cannot fill alone, widen the range of choices open to people, and enable each person to live as fully human as possible.
Using acoustic signal processing, VR/AR, and AI technologies, the lab aims to build systems that augment human perceptual and physical abilities.
On the lab's website, it is presented under the name "XperLab."
Key terms
- Umwelt
- The world as each individual perceives it and gives it meaning.
- Actor chimera
- An entity in which service producers (service actors) are partially merged.
- Nonverbal information
- Information in conversational speech other than the meaning of the words, such as tone of voice and backchannel responses.

ResearchResearch themes
The lab aims to blur the boundary between cyberspace and physical space and to remove the barriers between roles, such as producer and consumer, or on-site and remote. Using acoustic signal processing, VR/AR, and AI technologies, it aims to build systems that augment human perceptual and physical abilities.
*Illustrative imageValue co-creation with merged avatars
The lab builds spaces in VR where services can be provided, and explores future services using avatars in which multiple people are merged into one. It aims to clarify how the actor chimera affects productivity and to establish design methods for value co-creation.
*Illustrative imageUmwelt and sound perception
The lab analyzes how each person's "Umwelt" affects the perception of sound. It aims to apply the results to experience design and service design.
*Illustrative imageMeasuring co-created value from conversational speech
The lab aims to build systems that infer co-created value from nonverbal information in conversational speech, such as tone of voice and backchannel responses. It is developing technology that measures the timing and sense of distance of expert retail staff (joint research with the College of Policy and Planning Sciences) and a medical service that infers patients' psychological state to give them reassurance (joint research with the National Cancer Center).
*Illustrative imageNext-generation psychotherapy through human augmentation
Using remote collaboration technology and acoustic interfaces, the lab develops a new human-augmentation approach to support psychotherapy in clinical settings.
