The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is the development of automatically refocusing reading glasses for the two billion people with presbyopia, a common form of vision loss with age that prevents focusing on nearby objects. Current presbyopia corrections, such as reading glasses, bifocals, or progressive lenses, are unwieldy or unnatural solutions that do not replace healthy vision. An automatically refocusing system will provide an attractive alternative by restoring natural vision, such that objects are brought into focus according to the user’s gaze. Furthermore, the loss in productivity brought on by presbyopia in workers in industrial sectors will open an immediate opportunity in the aging skilled labor market, where an automatically refocusing system will offer significant benefits and users will tolerate a wider range of form factors. This Small Business Innovation Research (SBIR) Phase I project aims to study basic vision science and user behavior in interaction with an automatically refocusing system for presbyopia correction, address design requirements for deployment at scale, and build a prototype system to validate novel focus depth estimation techniques that can reach the power and miniaturization targets of a commercial head-mounted product. Current state-of-the-art eye tracking systems address only the highest performance implementations of full 3D gaze estimation. The main technical objective is the design of a low-power depth estimation technique.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小型企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是为20亿老花眼患者开发自动重新聚焦阅读眼镜，老花眼是一种常见的视力丧失形式，随着年龄的增长，无法聚焦在附近的物体上。目前的老花眼矫正，如阅读眼镜、双光眼镜或渐进镜片，是不实用或不自然的解决方案，不能取代健康的视力。自动重新聚焦系统将通过恢复自然视觉来提供有吸引力的替代方案，使得根据用户的注视使对象聚焦。此外，工业部门工人的老花眼所带来的生产力损失将在老龄化的熟练劳动力市场中立即打开机会，其中自动重新聚焦系统将提供显着的好处，并且用户将容忍更广泛的形状因素。该小型企业创新研究（SBIR）第一阶段项目旨在研究基础视觉科学和用户行为与用于老花眼矫正的自动重新聚焦系统的交互，解决大规模部署的设计要求，并建立一个原型系统来验证新的焦点深度估计技术，该技术可以达到商业头戴式产品的功率和小型化目标。当前最先进的眼睛跟踪系统仅解决全3D凝视估计的最高性能实现。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
