PORTABLE TELECOMMUNICATIONS DEVICE FOR DEAF

Nexus Engineering计划在其第一阶段工作和开发的基础上进行构建 一种新型的超小型便携式电信设备，用于 聋人(TDD)。新设备将主要不同于现有的TDD 因为它极其紧凑。设备尺寸应为2.5英寸左右 X 4.5“x 0.6”，便于携带 在日常活动中。这将提供随时付款的途径 电话和其他远离TDD的电话，供聋人或语言使用者使用 受伤了。 在第一阶段中，尺寸为2.4“x 4.3”x 1.4“的全功能TDD (14.45英寸-3)，以及实现TDD的技术 通讯发达。我们的研究表明，这一阶段存在问题 I文本输入技术，解决这个问题的新方法是 在第二阶段中提出。 替代功能将内置到第二阶段设备中，这将 提高其有用性和商业成功。

Nexus Engineering proposes to build upon its Phase I work and develop a new type of very miniature portable telecommunications device for the deaf (TDD). The new device will differ from existing TDD's primarily in its extreme compactness. The device dimensions should be about 2.5" x 4.5" x 0.6", which will allow it to be conveniently carried throughout everyday activities. This will provide ready access to pay phones and other phones away from TDD's for the deaf or speech impaired. In the Phase I a fully functional TDD of dimensions 2.4" x 4.3" x 1.4" (14.45 in-3) was constructed, and the technology to implement TDD communications developed. Our research showed problems with the Phase I techniques for text entry, and a new approach to this problem is proposed in the Phase II. Alternate functions will be built into the Phase II device which will increase its usefulness and commercial success.
