Center for Cognitive Ubiquitous Computing

Center for Cognitive Ubiquitous Computing. The Center for Cognitive Ubiquitous Computing is a multidisciplinary research unit established at Arizona State University in 2004. Founded and directed by Sethuraman Panchanathan, who later became director of the National Science Foundation, the center focuses on creating intelligent systems that assist individuals, particularly those with disabilities. Its work sits at the intersection of artificial intelligence, human-computer interaction, and pervasive computing.

Overview

The center was launched under the leadership of Sethuraman Panchanathan, then a professor at the Fulton Schools of Engineering at Arizona State University. Its creation was supported by significant funding from the National Science Foundation and aimed to pioneer a new paradigm in assistive technology. The research philosophy emphasizes human-centered design, where technological innovation is driven by the needs of the end-user. This approach has positioned the center as a leader in developing cognitive assistance technologies that are both context-aware and personalized.

Research Focus

Primary research investigates how machine learning and sensor networks can create systems that understand and respond to human intent and the surrounding environment. A major theme is enhancing human perception and cognition, especially for individuals with sensory impairments such as visual impairment or hearing loss. Work includes developing novel computer vision algorithms for scene description and creating haptic technology interfaces for conveying graphical information. The center also explores affective computing to enable systems to recognize and respond to human emotional states.

Key Technologies and Projects

Notable projects have produced groundbreaking assistive devices and software frameworks. The **iCARE** project developed a wearable camera system that could identify currency, read text, and recognize faces for users with visual impairments. Another initiative, **Social Interaction Assistant**, utilized augmented reality and real-time computing to provide conversational cues for individuals with social communication challenges. Research into **multimodal interaction** has led to systems combining speech recognition, gesture recognition, and eye tracking for seamless control of intelligent environments. The center has also contributed to foundational work in mediator-based software architecture for ubiquitous systems.

Collaborations and Partnerships

The center maintains extensive collaborations with academic, governmental, and industrial partners. Within Arizona State University, it works closely with the School of Computing and Augmented Intelligence and the College of Health Solutions. Externally, it has partnered with the National Institutes of Health, the U.S. Department of Education, and the Smith-Kettlewell Eye Research Institute. Industrial collaborations have included projects with Intel, Microsoft Research, and Google. These partnerships facilitate translational research, from fundamental science to deployed prototype testing in real-world settings.

Impact and Applications

The research has had a tangible impact on the field of assistive technology and ambient intelligence. Technologies pioneered have been transitioned to commercial products and open-source platforms, increasing independence for users with disabilities. The work has influenced policy discussions on accessible technology, contributing to standards considered by the World Wide Web Consortium and the International Organization for Standardization. Furthermore, the center's graduates have assumed key roles in industry and academia, spreading its human-centered philosophy to organizations like IBM Research, Apple Inc., and Carnegie Mellon University.
