Abstract

 The process of introducing emotion can be improved through three-dimensional (3D) tutoring system. The problem that still not solved is how to provide realistic tutor (avatar) in virtual environment. This paper  propose an approach to teach children on understanding emotion sensation through facial expression and sense of touch (haptic).The algorithm is created by calculating constant factor (f) based on maximum value of RGB and magnitude force then magnitude force range will be associated into particular colour. The Integration process will be started from rendering the facial expression then followed by adjusting the vibration power to emotion value. The result that achieved on experiment, it show around 71% students agree with the classification of magnitude force into emotion representation. Respondents commented that high magnitude force create similar sensation when respondents feel anger, while low magnitude force is more relaxing to respondents. Respondents also said that haptic and facial expression is very interactive and realistic.

Abstract

In this research, we would like to present virtual reality application that will visualize Graha Amerta Surabaya hospital into Virtual environment. This 3D simulation is for helping people on remembering hospital area. There 3 different categories: road way around hospital, lobby reception and VIP room for patient. Guidance process involve Dijkstra   algorithm for looking shortest path to specific location. The result of simulation still not perfect because of the coordinate of building still not precise. In other ways, there also difficulty of customize the building became look similar with the real, it’s because of the addition on building will increase the number of polygon, there fore memory needs will also increase.
