PORTABLE TELECOMMUNICATIONS DEVICE FOR DEAF

Nexus工程公司建议在其第一阶段工作的基础上， 一种新型的非常微型的便携式电信设备， 耳聋（TDD）。 新设备主要与现有的TDD设备不同 在它的极端紧凑。 设备尺寸应为约2.5” x 4.5”x 0.6”，便于携带 在日常活动中。 这将提供便捷的支付方式， 电话和其他电话远离TDD的聋人或讲话 受损 在第一阶段，全功能TDD尺寸为2.4”x 4.3”x 1.4” （14.45 in-3）的基础上， 通讯发达。 我们的研究表明， I技术的文本输入，和一个新的方法，这个问题是 在第二阶段提出。 替代功能将内置于第二阶段设备中， 增加其实用性和商业成功。

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.
