Three sub-projects with how existing and emerging technologies can aid older adults in the work force to maintain high productivity and those who retire to remain independent and to function on a high level despite age- related declines in cognitive, perceptual, and psychomotor capabilities. The first project deals with determining the relative utility and cost effective- ness of standard (mouse) and non-standard (lightpen, speech recognition, gaze selection) computer pointing devices fro adults in pure pointing and in mixed pointing and data entry tasks. The second project focuses on assessing the utility of speech recognition software for younger, middle- aged, and older adults in light of how voice characteristics of older adults (particularly age-related increases in variability) affect performance with this software. These studies investigate training time, accuracy levels, and acceptability of this software for navigation and data entry tasks. The third project focuses on the effectiveness of desktop videoconferencing for a variety of tasks. It investigates the utility of such systems at different transmission bandwidths and image sizes and also compares the relative effectiveness of "voice over Internet Protocol" to telephone communication. Component tasks investigated include conveying emotional state, conveying phonetic information, and collaborating on way-finding tasks. These projects will provide human factors guidelines for how to design usable and useful interfaces for older adults, and how to train their effective use.

三个对现有技术和新兴技术如何帮助劳动力中的老年人保持较高生产力的次要投影，以及那些退休的人保持独立并在高水平上发挥作用，尽管年龄相关，认知，感知和精神运动能力的下降也有所下降。第一个项目涉及确定标准（鼠标）和非标准（Lightpen，语音识别，注视选择）的相对效用和成本效益，计算机指向成年人以纯指向和混合指向和数据输入任务的设备。第二个项目着重于评估年轻，中年和老年人的语音识别软件的实用性，以了解老年人的语音特征（尤其是与年龄相关的可变性）如何影响该软件的性能。这些研究研究了该软件在导航和数据输入任务中的培训时间，准确性水平以及可接受性。第三个项目着重于桌面视频会议对各种任务的有效性。它研究了此类系统在不同的传输带宽和图像大小上的实用性，还将“语音在互联网协议”与电话通信的相对有效性进行了比较。调查的组件任务包括传达情绪状态，传达语音信息以及在找到寻路任务上的协作。这些项目将为如何为老年人设计可用且有用的界面以及如何培训其有效使用的人为因素指南。
