We propose a mind map manipulation system, named MMVR. This system allows multiple users to edit a mind map by using hand gestures and to share it in virtual reality space. To implement the system, we leveraged a hand gesture tracker for quick, easy, and correct handling of mind map elements and a head-mounted display (HMD) for providing a wider workspace than a standard PC's screen. We conducted...
We have been studying a navigation system for the visually impaired using 3D audio. We proposed to give cues on the direction and distance to the target location using a simple 3D guidance audio. We implemented a prototype 3D audio navigation system, and conducted experiments using this prototype. We investigated the influence that sound pressure level differences of navigation sound gave for a route...
Spoken dialog systems are presently used widely. However, some users avoid using them because of poor usability and unattractiveness. In this study, we develop a system that captures the user's movement and estimates the user state. This function is incorporated into the existing spoken dialog system to build a multimodal dialog system. In the experiments, the recognition performance of body motion...
We evaluated usability by feedback of human senses ("Sight", "Hearing", and "Haptics") in non-contact operation system using non-contact display. We performed the experiments in conditions of single, double and all human senses (totally seven conditions). In the experiments, distance between feedback threshold and reaction points, number of operation error and time of...
There are diverse alternatives in the competitive market when a consumer would like to purchase an electronic product; however, choosing a suitable electronic product is a challenging problem considering multiple criteria such as price attractiveness, brand, functionality, usability, performance and warranty. To address this issue, this paper introduces the Primitive Cognitive Network Process (PCNP)...
Due to the continuously growing possibilities provided by technology and its wider application, today's IT products are becoming more and more complex both from technical and managerial standpoints. Very often, multiple parties are involved in their development. Consequently, the organization of the integration and testing of these products gets increasingly complex. Organisations already encounter...
