The proposed innovation is an inexpensive, visible light information transfer system (VLITS) to transmit data to a personal data display (PDD) that can be used to convey information to deaf and hard of hearing users. VLITS is remarkably inexpensive because it requires no additional or special wiring other than that already typically installed for existing lighting fixtures. The network uses currently installed visible lighting, such as incandescent or fluorescent lighting, as the carrier medium for the data. The PDD receives information transmitted to a user over ambient room lighting and provides it to the user in graphical or textual form. The system varies the light output of lighting fixtures to transmit data at a sufficiently rapid rate that there is no susceptible visual flicker in light output. Data encoded in the lamp light is sent to a small personal data display that presents textual or graphical information to the deaf and hard of hearing meeting participants, students, travelers or occupants of a building. The system will be developed in connection with deaf and hard of hearing users and will be evaluated and tested by these users to maximize its user friendliness and value. PROPOSED COMMERCIAL APPLICATION: Assistive network for deaf and hard of hearing users comprising: 1. conventional lighting fixtures 2. modified light ballasts 3. graphical/textual receivers

拟议的创新是一种廉价的可见光信息传输 系统(VLITS)将数据传输到个人数据显示器(PDD)，该个人数据显示器可以 用于向聋哑人和重听人传达信息。 VLITS非常便宜，因为它不需要额外的或特殊的 现有照明设备通常已安装的布线以外的布线 固定装置。网络使用当前安装的可见光，例如 白炽灯或荧光灯，作为数据的载体介质。这个 PDD接收通过环境房间照明传输给用户的信息，并且 以图形或文本形式将其提供给用户。系统会改变光线 以足够快的速率传输数据的照明设备的输出 光输出中没有易受影响的视觉闪烁。在灯中编码的数据 被发送到呈现文本或图形的小型个人数据显示器 向聋人和重听人提供信息会议参与者、学生、 建筑物的旅行者或居住者。该系统将于年开发。 与聋人和重听人的联系，并将进行评估和测试 由这些用户最大限度地提高其用户友好性和价值。 建议的商业应用： 为聋人和重听用户提供的辅助网络包括： 1.常规照明灯具 2.改进型轻型镇流器 3.图形/文本接收器
