Dynamic Visual Acuity (VA) Test - Market Assessmen

Waterloo的动态视力测试使用不同的视标目标运动、速度、颜色和对比度来评估许多不同的视力，从而解决其竞争对手的局限性。当前竞争性的计算机化动态视力表仅使用在可预测的水平或旋转方向上移动的视标，或者仅使用在白色背景上的高对比度目标。市售动态VA测试均未通过与金标准静态VA测试进行比较或评估重测信度进行验证，这限制了其临床实用性。通过测量静态，随机运动，水平，垂直和倾斜运动以及抖动，滑铁卢的软件克服了可预测性的局限性。它还克服了具有不改变的视标的问题，因为每个呈现的视标是从4到10个不同的字母中随机选择的。它已被验证并用于比较运动员与视频游戏玩家和非运动员的动态VA的研究，用于视力障碍的残奥会运动员的分类研究，以及检查咖啡因对视觉功能影响的研究。 该技术的一些优点包括：（1）允许测量许多不同的静态和动态视力（2）视力可以在高对比度和低对比度下测量，并且具有不同的目标和背景颜色（3）动态视力在常见的临床视力单位中测量，和（4）已被证实具有与临床金标准静态视力测试的重测信度相当的重测信度。 作为该市场评估赠款的一部分，选定的顾问（Adventus）将进行全面的市场分析，以确定最合适的市场机会，沿着与特定细分市场中技术应用相关的技术，营销和财务挑战。有利的市场评估结果将1）制定商业化战略并帮助吸引潜在的许可证持有人2）为提交后续NSERC I2I第1阶段项目提案奠定基础。

Waterloo's Dynamic VA Test assesses a number of different visual acuities using different optotype target motions, speeds, colours and contrasts, thereby addressing limitations of its competitors. Current competitive computerised dynamic VA charts only use optotypes that move in a predictable horizontal or rotational direction or only use high contrast targets on a white background. None of the commercially available dynamic VA tests are validated through comparison with gold-standard static VA tests or assessment of test-retest reliability, which limits their clinical utility. By measuring static, random motion, horizontal, vertical, and oblique motion as well as jitter, Waterloo's software overcomes the limitations of predictability. It also overcomes the issues with having optotypes that do not change because each presented optotype is randomly selected from 4 to 10 different letters. It has been validated and used in research comparing the dynamic VA of athletes to video gamers and non-athletes, in classification research for Paralympic athletes with vision impairment, and in research examining the impact of caffeine on visual function. Some advantages of this technology include: (1) Allows for the measurement of a number of different static and dynamic visual acuities (2) Visual acuities can be measured at high and low contrast, and with different target and background colours (3) Dynamic visual acuity is measured in a common clinical visual acuity unit, and (4) Has been validated with demonstrated test-retest reliability comparable to the test-retest reliability of the clinical gold standard static visual acuity tests. As part of this Market Assessment grant, the selected consultant (Adventus) will perform a thorough market analysis to identify the most suitable market opportunities along with technical, marketing and financial challenges associated with the application of the technology in a particular market segment. A favourable market assessment result will 1) formulate the commercialization strategy and help attract potential licensees 2) form the basis for submitting a follow-on NSERC I2I Phase 1 project proposal.
