Speech Title: Braille Recognition System

Abstract: Finger Braille is one of the communication media of deafblind people. In one-handed Finger Braille, a sender dots the left part of the Braille code on the distal interphalangeal (DIP) joints of the index, middle and ring fingers of a receiver, and subsequently dots the right part of the Braille code on the proximal interphalangeal (PIP) joints of the same fingers. To assist communication between deafblind individuals and non-disabled people, we have been developing a Finger Braille recognition system using small piezoelectric accelerometers worn by the receiver. The recognition system recognizes the dotting of Finger Braille by the deafblind person and synthesizes this tactile communication into speech for the non-disabled person. The accelerometers were mounted on the top of finger rings. The results of the evaluation experiment showed that the recognition system could recognize the dotted fingers and positions accurately when the interpreter dotted clearly.

Speech Title: The Effect of Computer Graphics Techniques on Perceiving Depth in Virtual Environments

Abstract: 3D stereoscopic devices have been utilized in a variety of areas such as entertainment, simulation, training, education, and medicine. It provides depth perception advantages, but there are known limitations that prevent users from accurately perceiving depth. The lack of natural depth cues and differences between the user’s actual convergence in reality and the viewer’s convergence on the screen can make depth perception difficult. Researchers have studied techniques to improve the perception of users in examining stereoscopic images and reduce visual fatigue when they use 3D vision technology. Previous studies have produced mixed results, showing a general trend of underestimation in depth perception in 3D environments. This study examines the influence of graphics techniques selectively applied to 3D images for reducing measurement errors. The experimental results presented outcomes in perceiving depth that changed depending on the use of techniques and image types. The study reemphasizes the significance of utilizing depth cues and also suggests future research directions for investigating impacts of depth cues.

Speech Title: Deep Learning Methodologies in Smart Assistive Lifecare Technologies

Abstract: Due to the rapid increase in the elderly population, the field of assistive lifecare technologies is also advancing rapidly. The goal of assistive lifecare technology is to increase the quality of life and to promote the health of residents proactively, especially for the elderly, for ambient assisted living. In general, smart sensors and devices in smart environments are active components of ambient assisted living technologies. Also they provide alternative means of e-healthcare over caregivers or institutional care. In this presentation, how deep learning methodologies can be applied to these smart multi-modal sensors and devices for assistive lifecare technologies. Various topics including human activity recognition, human motion recognition, life event detection, lifelogging, etc. will be covered.
