Augmented Reality Musical Instrument

Name: Pengzhi Zhou


Playing a musical instrument has been proven to improve cognitive functions, help fight memory loss, reduce stress, lower blood pressure and help prevent depression in the developing brain. But if we want to play the physical instruments we have to come to specify place or just buy them home, and the problem as high price(such as piano) or discommodious that stops many people from getting approach to them. So if we can control the visual 3D instruments using our hands movement, it will be a facility to the people who like to play the varieties kinds of instruments. The aim of this project is to develop a system that allows a person to control a visual instrument using hand gestures. In order to track and recognise the hand gestures, the system must be able to detect and track the customer’s hand and recognise the hand gestures. And because our objective is to control the musical instruments, for lifelike the system will be produced in Augmented Reality environment.
