In the two‐alternative forced‐choice (2AFC) paradigm, manual responses such as pointing have been widely used as measures to estimate cognitive abilities. While pointing measurements can be easily collected, coded, analyzed, and interpreted, absent responses are often observed particularly when adopting these measures for toddler studies, which leads to an increase of missing data. Although looking...
We present a method for vision-based speaker identification in a group conversation. The group context in the conversation is modeled by the integrated face direction of group members. Experimental results show that integrated face direction of group members is effective for speaker identification in a group.
Live instructors perspective videos are useful to present intuitive visual instructions for trainees in medical and industrial settings. In such videos, the instructors hands often hide the work area. In this demo, we present a diminished hand for visualizing the work area hidden by hands by capturing the work area with multiple cameras. To achieve the diminished reality, we use a light field rendering...
Instructor's perspective videos are useful for presenting intuitive visual instructions for trainees in medical and industrial settings. In such videos, the instructor's arms often obstruct the trainee's view of the work area. In this article, we present a diminished reality method for visualizing the work area hidden by an instructor's arms by capturing the work area with multiple cameras. To achieve...
Understanding the anatomy of the human body is vital for everyone working in the medical domain. Augmented reality (AR) systems for anatomy teaching, which display virtual information directly on top of a users' body, have proven to facilitate mental mapping compared to traditional teaching paradigms. In this paper, we explore the potential of diminished reality (DR) in the context of anatomy education...
This paper proposes a remote welding robot manipulation system by using multi-view images. After an operator specifies two-dimensional path on images, the system transforms it into three-dimensional path and displays the movement of the robot by overlaying graphics with images. The accuracy of our system is sufficient to weld objects when combining with a sensor in the robot. The system allows the...
