• Virtual swimmer - to swim in the standard way (the correct way) which means to move his arms, head and legs in the most accurate and correct way .
• Each student wearing the headset can see the virtual swimmer and follow him ( the student will be laying on a table and moving his arms as swimming to give him the feeling like he is in the water and swimming.
• The teacher can control the movement of the virtual trainer for all students at same time, he can pause the trainer at certain point or angle to focus on some information and can navigate all direction of views around the trainer.
• The teacher can control the movement of the trainer arms and /or legs to demonstrate the wrong movements – not important
• No need the students to see each other’s (avatars) but each student will be act like swimming with the same virtual trainer.
• All at same time, which means teacher can control the virtual trainer for all students at same time - from PC if possible and from the VR.
• The environment of university swimming pool.
