A Gamification System Design For Full Body Balance Training Based On Dual-task Theory

The problem of ageing in Chinese society is becoming increasingly serious and falls can cause serious physiological damage to older people and even endanger their lives.Balance training can help older people improve their balance and reduce the risk of falls,but the training process is tedious and difficult to motivate the trainer.In this study,a gamified balance training system was designed in which the trainer has to perform two tasks simultaneously: controlling the center of the trunk to a specified position,and judging the type of target and swinging the upper limb in the direction of the specific target.Compared to traditional balance training methods,this study has three main innovations: the system introduces an additional task of cognitive judgement in body movements,which increases the cognitive load during training and can optimize the training effect;the system includes changes in whole-body posture and the amplitude and angle of training movements are continuously variable,which can better simulate complex real-life scenarios and reduce the idiosyncratic limitations of the training effect The system is designed to make the training process fun and interesting,increasing the motivation of older people and improving their training experience.During training with the system,the trainer’s game score tends to increase with each round.The maximum distance that the trainer could control the center of mass to drift in each direction increased after the training was completed,while the maximum distance that the center of mass could sway decreased when disturbed by random external forces.The results of the game experience scale showed that the trainers were more engaged in the training and felt a positive experience of the game.These results suggest that the system can improve the trainer’s balance and create a good training experience.
