title: Foot Tracking with Pedestrian Tracking Camera & Foot Mounted IMU
abstract: In the field of gait tracking and analysis, accurate tracking of the trajectory and position of the foot is required to better capture the walking pattern of a person, which would then enable rehabilitation centres to diagnose motor impediments and better predict the health of a patient more reliably. The current standard of tracking involve the use of motion cameras and tracking markers to track the joints of a person however such equipment are usually large, complicated with high operational costs. Furthermore, current systems can only be operated indoors. Being able to track a person's gait pattern reliably both indoors and outdoors with ease can give an extra dimension of data to improve gait tracking and analysis. In this study, we propose a system that can overcome the weaknesses of current systems through the use of a LIDAR enabled smartphone camera that follows a pedestrian with foot mounted IMUs, while 3d body tracking data from the pedestrian and output data from the IMU will be fused through a sensor fusion algorithm to create a better estimation of the pedestrian's foot trajectory and position while being able to track the pedestrian in both indoors and outdoors settings. language of the presentation: English | |||

title: *** The Impact of Avatar Transition in Augmented Reality on Surface Electromyography and Sense of Embodiment ***
abstract: *** Virtual avatars can change the users' appearance not only in virtual reality (VR) but also in augmented reality (AR). Prior studies have shown that avatar appearance can influence the user's attitude and behavior. However, little is known about how the transitions to a new avatar’s appearance impact a user's surface electromyography (sEMG) magnitude and subjective experience. In this paper, active and passive transitions during avatar modification are compared in AR. In the active transition, users see their own image in the beginning, which is transformed into a normal body avatar automatically in 10 seconds. This avatar is then further transformed into a muscular body avatar in 30 seconds as they strongly contract the arm muscles. In the passive transition, users experienced the same transition automatically without physical action. An experiment was conducted to investigate the influence of the two types of transitions on the user’s physical performance and the sense of embodiment (SoE) with the avatar. The results show that participants who experienced the active transition to embody a muscular avatar had an increased sEMG magnitude compared to the passive transition. Furthermore, we found that the active transition positively influenced the sense of agency and the sense of self-location, whereas it negatively impacted the sense of agency. We also confirmed that the active transition increased the sEMG magnitude during embodiment, and the passive transition increased the sEMG magnitudes after embodiment. *** language of the presentation: *** English *** 発表題目: *** この部分を発表題目に *** 発表概要: *** この部分を発表概要に *** | |||
