The virtual human play vital roles in virtual reality and game. The process of Enriching the virtual human through their expression is one of the aspect that most researcher studied and improved. This study aims to demonstrate the combination of facial action units (FACS) and facial muscle to produce a realistic facial expression. The result of experiment succeed on producing particular expression such as anger, happy, sad which are able to convey the emotional state of the virtual human. This achievement is believed to bring full mental immersion towards virtual human and audience. The future works will able to generate a complex virtual human expression that combine physical factos such as wrinkle, fluid dynamics for tears or sweating.

The stroke patient will be having difficulty to control their upper limb, which causes their handling to become weak and unorganized. Conventional therapy designed to retrain the subject ability when it's losses due to stroke. As previous study concern that a subject with strong motivation and concentration of treatment tends to recover better than people who don't follow the program. This research focused on intensifying the training by providing user with Wheel robotic arm to train their upper limb. User will be asked to do exercising on moving particular objects to another position repetitively during a specific period. The robot will help the user to assist and relearn their motoric skill and improve muscle strength and coordination. The result of training is quite convincing when the user gives a positive response toward the practice. Around 86 percent of subject likely prefer the proposed system as their home-based rehabilitation system. The Anova testing with alpha 0.05 shows that there is no significant difference between trained subject and untrained subject on operating the wheeled robotic arm. It's mean the proposed system is reliable and user friendly to be used without an assistant so user can have more flexibility and improve their accomplishment on regaining their motoric skills. The future work will focus on stroke patient testing with more challenge and obstacle in enhancing the effectiveness of the stroke rehabilitation system.

In recent years, Augmented Reality (AR) has received increasing emphasis and researchers gradually promote it Over the worlds. With the unique abilities to generate virtual objects over the real-world environment, it can enhance user perception. Although AR recognised for their enormous positive impacts, there are still a ton of matters waiting to be discovered. Research studies on AR toward conceptual change, specifically in scientific concept, are particularly limited. Therefore, this research aims to investigate the effect of integrating AR on conceptual change in scientific concepts. Thirty-four primary school students participated in the study. A pre-test and post-test were used to assess participants’ understanding of the scientific concepts before and after learning through AR. The findings demonstrated that 82% among them had misconceptions about the scientific concepts before learning through AR. However, most of them (around 88%) able to correct their misconceptions and shifted to have a scientific conceptual understanding after learning through AR. These findings indicate that AR was effective to be integrated into education to facilitate conceptual change.

Robotic technology has affected the education field, and even early education involves robot to attract Kids. Technical education is the notion of giving students knowledge of robots and technology. The main contribution of our research is to provide an interactive way of learning for kids through play and fun method. Two approaches proposed here: first, we provide an interactive game by touching robots body parts to teach kids how they were practising their motoric nerve and the listening to the instruction. In this game, kids asked to find some robot parts such as right hand, or left hand, where it equipped with a tactile sensor. The game difficulty can be increased by setting up the time limit for the answer and make kids touch the body parts of the robot very fast. The second learning method is practising number counting and pronunciation with NAO Robots. The robots will do computer vision processing to analyse and pronounce the kids handwriting with an artificial neural network. The result of implementation has obtained more than 75% success rate on recognition part with loss es than 0.6. The system received strong appreciation from kids and their parent, while This research believed able to attract kids to study in interactive and fun ways.
