Despite of the established evidence in favor of exergames for physical rehabilitation their use is limited in Pakistan. In our user study with game developers (N=62), majority (67.7%) of the participants believed that exergames' popularity will increase if cheap alternatives of body tracking devices are available. Perhaps, custom controllers can be used as an affordable alternate input source in exergames but the lack of hardware programming knowledge and shortage of experience in the embedded programming attribute to the little involvement of game developers (11.3% of the participants) in the area of exergames. This paper presents a library for the integration of Arduino based (open-source and low-cost) tailored controllers to be used as input source in Unity3D (most preferred game development engine by 88.7% participants) based exergames. The interface to the library proposes a flexible and easy structure for programming and serve as a template application for a range of exergames.

翻译：尽管已有充分证据表明体感游戏在物理康复中具有积极作用，但其在巴基斯坦的使用仍有限。在我们对游戏开发者（N=62）进行的用户研究中，大多数参与者（67.7%）认为，如果存在价格低廉的体感追踪设备替代方案，体感游戏的普及度将会提高。或许，定制控制器可作为体感游戏中一种经济实惠的替代输入源，但由于缺乏硬件编程知识及嵌入式开发经验，导致游戏开发者在该领域的参与度较低（仅占参与者的11.3%）。本文提出一个用于集成基于Arduino（开源且低成本）定制控制器的程序库，该控制器可作为基于Unity3D（88.7%参与者首选的游戏开发引擎）开发的体感游戏的输入源。该程序库接口提供了灵活易用的编程结构，可作为一系列体感游戏的模板应用。
