Pulse is a vital sign that shows a patient’s health and can be used to identify symptoms. Nursing students have a low chance of practicing the measurement of the different varieties of pulses. Therefore, technology can solve this problem. The main objective of this study was to set up a pulse simulation using Augmented Reality (AR) and a haptic device (Phantom Omni) for generating virtual pulse patterns in normal and abnormal pulse waves by mathematical models. In this thesis, the pulse simulation was developed to support the training of pulse measurement for nursing students. By integrating the haptic device to the pulse simulation, the system provides the feeling of the characteristics of virtual pulse waves by the force feedback response. The methods were as follows: 1) the modeling of the virtual 3D arm; 2) the programming of the square, sine, and Gaussian function for pulse force generation; and 3) the evaluation processes of haptic rendering and performance. The pulse simulation was adjusted to a pulse rate between 40-160 beats per minute (bpm), a pulse force between 0-1 Newton (N), and pulse patterns that can be selected during the training. The evaluation of the accuracy of the pulse simulation in terms of performance was done by a group of experts and nurses. Nursing students conducted the experiments of pulse measurement and evaluated usability satisfaction. The results of the system evaluation were positive in all categories of the questionnaire.
