Abstract

Previous research proposed a wide range of interaction methods and use cases based on the previously unused back side and edge of a smartphone. Common approaches to implementing Back-of-Device (BoD) interaction include attaching two smartphones back to back and building a prototype completely from scratch. Changes in the device's form factor can influence hand grip and input performance as shown in previous work. Further, the lack of an established operating system and SDK requires more effort to implement novel interaction methods. In this work, we present a smartphone prototype that runs Android and has a form factor nearly identical to an off-the-shelf smartphone. It further provides capacitive images of the hand holding the device for use cases such as grip-pattern recognition. We describe technical details and share source files so that others can re-build our prototype. We evaluated the prototype with 8 participants to demonstrate the data that can be retrieved for an exemplary grip classification.

在整个设备表面实现触摸交互的智能手机原型

之前的研究基于智能手机以前未使用的背面和边缘，提出了广泛的交互方法和用例。实现设备后端交互(BoD)的常见方法包括将两台智能手机背靠背连接起来，并从头开始构建原型。如前所述，设备外形因素的变化会影响握持力和输入性能。此外，由于缺乏成熟的操作系统和SDK，需要付出更多的努力来实现新的交互方法。在这项工作中，我们展示了一个运行Android的智能手机原型，其外形因素几乎与现成的智能手机相同。它还提供了手持设备的手的电容图像，用于握持模式识别等用例。我们描述技术细节并共享源文件，以便其他人可以重新构建我们的原型。我们评估了8名参与者的原型，以证明数据，可以检索一个典型的抓地力分类。
