In this paper, several physical activity-based human–computer interaction (HCI) games which are developed and implemented for the improvement of attention, emotion, and sensory–motor coordination will be presented. The interface and the difficulty levels of these games are specially designed for the use of people with different age groups and disabilities. The games involve physical activities for the fulfillment of some basic HCI tasks which require hand and arm motion for control, such as fruit picking and air hockey, with adaptive difficulty levels based on varying parameters of the games and human performance. In the fruit picking game, several fruit images are moving from top to the bottom of the screen. Objective is to collect apples while avoiding the pears. The player’s hand will control the basket that collects the fruits. In the air hockey game, the player will try to score goals against computer-controlled opponent. The player’s hand will control the paddle to hit the puck to score or to defend his/her goal area. The player’s hand is recognized by Kinect RGB-D sensors in both games. Aim of the adaptive difficulty-based system is keeping the players engaged in the games. The games are tested with a group of deaf children (3.5–5 years) as a part of an ongoing project,1 to decrease the stress of the children and increase their positive emotions, attention, and sensory–motor coordination before the audiology tests. The game performances and the evaluation of the therapists show that the games have a positive impact on the children. The games are also tested with a group of adults as a control group, where a mobile EEG device is employed to detect the attention levels. For this purpose, the adults also attended a third game featuring a maze and controlled with Myo sensors.

开发自适应人机交互游戏以评估注意力

在本文中，将介绍几种基于身体活动的人机交互 (HCI) 游戏，这些游戏是为提高注意力、情绪和感觉-运动协调而开发和实施的。这些游戏的界面和难度级别是专门为不同年龄段和残疾的人设计的。这些游戏涉及用于完成一些需要手和手臂运动来控制的基本 HCI 任务的体育活动，例如水果采摘和空气曲棍球，并根据游戏的不同参数和人类表现而自适应难度级别。在水果采摘游戏中，几张水果图像从屏幕顶部移动到底部。目标是收集苹果，同时避开梨。玩家的手将控制收集水果的篮子。在空气曲棍球比赛中，玩家将尝试与电脑控制的对手进球。球员的手将控制球拍击球得分或防守他/她的球门区域。在两款游戏中，Kinect RGB-D 传感器都能识别玩家的手部。基于自适应难度的系统的目标是让玩家参与游戏。作为正在进行的项目的一部分，这些游戏由一群聋哑儿童（3.5-5 岁）进行测试，1在听力学测试前减轻孩子的压力并增加他们的积极情绪、注意力和感觉-运动协调。游戏表演和治疗师的评价表明，游戏对孩子们产生了积极的影响。这些游戏还以一组成年人作为对照组进行了测试，其中使用移动脑电图设备来检测注意力水平。为此，成年人还参加了第三场以迷宫为特色并由 Myo 传感器控制的游戏。
