“…All about the interactivity that considered as the most important aim to be accomplished in the course of games that based on the virtual reality environment. [19] Believed that the main component that makes the 3D Virtual Human animation realistic, possibly will be walking as real, feeling as real, acting as real, gaze moving as real and talking as real. Currently, in the course of 3D Virtual Human animation in gaming domain the 3D Virtual Human come into sight to be quite real like, however there are still existing barriers in expressing emotions of 3D Virtual Human in depth.…”

A Brain-Computer Interface (BCI) is the device that can read and acquire the brain activities. A human body is controlled by Brain-Signals, which considered as a main controller. Furthermore, the human emotions and thoughts will be translated by brain through brain signals and expressed as human mood. This controlling process mainly performed through brain signals, the brain signals is a key component in electroencephalogram (EEG). Based on signal processing the features representing human mood (behavior) could be extracted with emotion as a major feature. This paper proposes a new framework in order to recognize the human inner emotions that have been conducted on the basis of EEG signals using a BCI device controller. This framework go through five steps starting by classifying the brain signal after reading it in order to obtain the emotion, then map the emotion, synchronize the animation of the 3D virtual human, test and evaluate the work. Based on our best knowledge there is no framework for controlling the 3D virtual human. As a result for implementing our framework will enhance the game field of enhancing and controlling the 3D virtual humans’ emotion walking in order to enhance and bring more realistic as well. Commercial games and Augmented Reality systems are possible beneficiaries of this technique.

“…Virtual human (avatar) has been studied often in recent times. Previous researches add human emotion from visual (facial expression) or sound effect to show behaviour of virtual human in virtual environment [12,13,14]. Touch gives a better opportunity to put on virtual human and add his ability to imitate real human due to haptic that can give bilateral exchange from physical world to virtual environment.…”

This study proposes a new method to augment the realism of avatar by using tactile vibration and facial expression. Currently, interactive game still lack of interactivity and immersiveness. In this paper, we create an avatar with some intelligence and emotional features in order to support the realism of avatar. Our approach based on mapping the 2D valence emotion diagram to particular magnitude vibration. We also consider the duration of vibration and the acceleration time that occurred during vibration. Through the experiment we succeed for classifying and mapping into two emotion states: angry and happy. Furthermore, our result has proven to differentiate in detail the emotion levels of angry. The result also compared to the previous result and we have obtained 35% until 55% better than the previous avatar in term of human perception that involved into avatar. This result is believed as well to enhance the interactivity and immersiveness of interactive game for overall.

Recently, Minimally Invasive Surgery(MIS) has come to the front. The research on surgical robot for operational support has been actively done. To use such robots in MIS, it is needed to estimate the environmental impedance as the numerical data and to preserve it as the standard reference value of the safety field of internal organs. In this paper, the environmental model considering nonlinear stiffness in real environment by bilateral control is proposed. The proposed method can estimate environmental model without depending on the initial position of a slave system and environmental surface. To verify the viability of the proposed method, experimental results are shown.
