This paper presents the extended work on LazyNav, a head-free, eyes-free and hands-free mid-air ground navigation control model presented at the IEEE 3D User Interfaces (3DUI) 2015, in particular with a new application to the head-mounted display (HMD). Our mid-air interaction metaphor makes use of only a single pair of the remaining tracked body elements to tailor the navigation. Therefore, the user...
In this study, we propose a method for estimating a user's fatigue resulting from mental load, such as office work, based on changes of luminance in facial images. Because these changes are influenced by vital signs such as heart rate and blood pressure, we consider that the level of fatigue is predictable with high accuracy by combining the features in the changes of luminance in the facial area...
This paper proposes an autonomous flying projector (AFP) that projects images from a micro aerial vehicle (MAV) on which a small projector is placed. The AFP works as a public and ubiquitous display, and has a potential for an expansion of projector applications (e.g., a digital signage moving in response to a distribution state of people, and the one following moving targets such as a person and...
The authors aim to develop a community detection system without constraining users. This paper introduces a method to detect communities in which users are engaging in a conversation with each other, by an ambient sensing of body sways and their synchrony between users. We apply an improved ambient sensing chair, which had been developed in our previous study. The system employs wireless force sensors...
