本文介绍了一种低成本、开源的辅助系统的设计和实现，该系统利用可穿戴设备来支持聋盲人使用马罗西字母进行交流。更具体地说，我们称之为GlovePi的系统由三个主要的低成本组件组成，例如：（i）园丁手套;（ii）Raspberry Pi;（iii）带有扩展板的MPR 121电容式触摸传感器模块。MPR 121模块作为Raspberry Pi和手套中传感器之间的桥梁，允许数据传输。相反，Raspberry Pi作为WiFi热点和服务器将数据传输到客户端（Android应用程序）。通过这种方式，双盲用户可以使用手套使用Malossi字母向其他用户传递信息。以这种方式创建的字符（和短语），将被发送到Android应用程序并显示或收听。已经进行了评估测试，以测量的基础上的假阳性和假阴性的性能，获得有趣的结果，支持这里描述的方法的可行性。
The paper presents the design and implementation of a low cost and open source assistive system exploiting a wearable device in order to support deaf-blind people in communication using the Malossi alphabet. More specifically, the system, that we called GlovePi, is composed by three main low cost components, such as: (i) a gardener glove; (ii) a Raspberry Pi; (iii) a MPR121 capacitive touch sensor module with expansion board. The MPR121 module works as bridge between the Raspberry Pi and the sensors in the glove, allowing the data transfer. Instead, the Raspberry Pi works as a hotspot wifi and as a server to transfer data to the client, an android application. In this way, the deaf-blind user can use the glove to deliver messages to other users, using the Malossi alphabet. The characters (and phrases) in this way created, will be sent to the android application and displayed or listen. Evaluation tests have been performed to measure the performance on the basis of false positive and false negative, obtaining interesting results in supporting to the feasibility of the here described approach.
