My research interest lies in situational control of end-user's cognitive distance (or management of attention demands) for seamless interaction between humans and computers. I will extend my research focus from human-centered problems dealing with cognitive or perceptual issues in HCI and the quality of life of people who want to overcome a difficulty in interacting with virtual information spaces (e.g., elder people or cognitively-disabled people).

Research Interest

Minimize Cognitive Distances!

Technology is giving us the ability to present information anywhere and anytime. Despite this ability, there is often a large gap or distance between physical spaces (i.e., the real world) and virtual information spaces. Depending on the relevance of the information being provided, the method of conveying information, and the user circumstances, this distance may be small or large. With a large gap, a user may take more time and may have to expend more cognitive effort to adjust from one space to another. We refer to this gap as the cognitive distance between computing and physical spaces. There are two distinct components that comprise cognitive distance. The first is the cognitive effort required to move one's attention from the physical space to the information space, and to locate the appropriate information within the information space. The second component is the effort required to move back from the information space to the physical space and apply the extracted information to the task at hand. As the effort required for either of these components grows, the overall cognitive distance grows.

Furthermore, if users are required to switch between these two spaces frequently, the impact of the cognitive distance can be even greater. This is particularly true for people who either have a cognitive difficulty, or are completing a task that is time-sensitive or has a high cognitive load associated with it.
