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.

Waterloo的Dynamic VA Test使用不同类型的目标运动、速度、颜色和对比度来评估许多不同的视觉敏锐度，从而解决其竞争对手的局限性。目前竞争激烈的计算机动态VA图表只使用在可预测的水平或旋转方向上移动的光类型，或者只使用白色背景上的高对比度目标。市面上可用的动态VA测试都没有通过与金标准静态VA测试或重新测试可靠性评估的比较来验证，这限制了它们的临床应用。通过测量静态、随机运动、水平、垂直和倾斜运动以及抖动，Waterloo的软件克服了可预测性的局限性。它还克服了光型不变的问题，因为每个呈现的光型是从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电子游戏玩家和非运动员的动态VA的研究，视力受损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)可以在高对比度和低对比度下测量视力；以及不同的目标和背景颜色；(3)动态视力是在一个常见的临床视力单位中测量的；(4)经过验证，证明了与临床金标准静态视力测试的测试重测可靠性相当。作为市场评估补助金的一部分，被选中的咨询公司（Adventus）将进行全面的市场分析，以确定最合适的市场机会，以及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有助1)制订商业化策略及吸引潜在持牌机构2)为提交后续的NSERC I2I第一期计划建议书奠定基础。
