Development of Virtual Pulse Simulation for Pulse Diagnosis Studies

Abstract

Pulse signals can be used to observe the early sign of patients' health problems. From medical researches, monitoring the characteristic of arterial pulse waveform shows some risk indicator of specific diseases, e.g., hypertension, cardiovascular and heart failure diseases. A simple way to get arterial pulse wave is by using fingers to touch the radial artery position on the wrist. In the traditional Chinese medicine, a physician can use the information of arterial pulse wave-form to identify diseases based on the physician’s ability and experience. The improvement of the skill in pulse measurement can be improved by training using various kinds of pulses that represent each disease. This paper proposes a development of the virtual pulse simulation using Augmented Reality (AR) and haptic device for pulse diagnosis studies under various situations. The pulse simulation generates arterial pulse waveforms based on Sine and Gaussian functions. In this study, the mathematical model can generate the pulse wave like human pulse by setting up specific parameters. We can generate pulse waveform which representing different kinds and states of diseases by varying the mathematical model and parameters such as pulse rate or pulse pressure. The features of this work include how to generate force feedback from the mathematical models using the haptic device and how the virtual 3D can display visual feedback. The pulse simulation is useful for the health sciences students, especially the nursing students in training to identify some diseases. The evaluation of the system was carried out by first-year nursing students regarding usability, satisfaction, and performance.

Design, Development and Evaluation of Haptic and Olfactory based Application for Visually Impaired Learners

“…Haptic devices are widely used in various fields such as, but not limited to, medicine, education, research, and training (Wong, et al, 2018). One of the well-known uses of haptic in the medical field is as a training tool for taking pulse and palpation (Kandee, Boonbrahm and Tantayotai, 2018). 3D systems, previously known as SensAble technologies, has developed a wide range of haptic devices, thereby becoming an option for researchers who do not want to develop their own haptic device (3DSystems, 2020a).…”

Mobile Simulator Control System for Isolating Breathing Apparatus of Software-Hardware Platform

“…The use of consumer fitness trackers of physical activity was considered as a possible solution [15]. However, proprietary operating systems installed on such devices greatly complicate the process of developing and integrating such platforms into training complexes.…”
