呼吸是一种无意识和不被注意的功能，一个健康的人每天大约发生20，000次，每年发生1000万次。与身体的其他无意识功能不同，呼吸可以被自主控制和调节。呼吸疗法的引入是为了帮助人们逐渐改善呼吸频率和呼吸量方面的呼吸模式。这是非常重要的人执行的确切指示，因为否则它可能会导致肺部问题。因此，呼吸专家和医生试图在多个练习会话中提供指导和反馈。为了克服这些局限性，这项工作提出并调查人工触觉刺激提供指示和反馈的呼吸练习在真实的时间的表现。所提出的系统包括一个单一的可穿戴传感器，该传感器从与振动电机集成的受试者的脐区域的内部/后部运动来模拟呼吸功能，以在呼吸治疗期间提供触觉生物反馈。研究结果是基于五种不同的瑜伽呼吸模式与10名健康志愿者。实验测试表明，当应用触觉反馈时，用户在呼吸治疗中的表现提高了40%以上。这显示了通过触摸通道来丰富可穿戴和便携式基于触摸的系统的质量的潜力。
Breathing is an unconscious and unheeded function occurs about 20,000 times per day and 10 million times per year by a healthy individual. Unlike other unconscious functions of the body, breathing can be controlled and regulated voluntarily. Breathing therapy was introduced to help people gradually refine their breathing patterns in terms of respiration rate and volume. It is very important for people to perform the exact instructions since otherwise it may cause lung problems. Therefore, the breath specialists and physicians try to provide instructions and feedback over multiple practice sessions. To overcome these limitations, this work proposes and investigates artificial tactile stimuli for providing instructions and feedback on performance of breathing exercises in real time. The proposed system comprises of a single wearable sensor that models the breathing functions from the interior/posterior motions of the subject's umbilical region integrated with a vibration motor to provide haptic biofeedback during breathing therapy. The results are investigated based on five different yogic breathing patterns with 10 healthy volunteers. Experimental tests have shown more than 40% improvement in users' performance in breathing therapy when applying haptic feedback. This shows a potential to enrich the quality of wearable and portable advisory-based systems through the touch channel.
