Challenges inherent in non-visual Web interaction prevent more than 2 million blind Americans from participating effectively in routine Web-based activities. The existing literature does not provide an understanding of cognition and subjective perception by visually-impaired people in these situations. Without this understanding, any effort to overcome the challenges of non-visual Web interaction will not be adequately informed. This project examines cognitive strategies employed by blind Web users that are distinct from typical sighted users. The research design used a problem solving framework to compare how blind participants and sighted participants "think aloud" while performing a series of web-based tasks. Activities where blind participants have difficulties, evidenced from their verbalizations, will be explored further in order to determine their cognitive strategies and how they differ from the strategies used by sighted persons. Web interaction is important to many day to day activities, including education, work, information seeking, shopping and socializing. More than 2 million visually-impaired Americans cannot participate effectively in these activities. Findings of this project may form the basis for interventions that allow enable blind people to overcome the challenges and participate effectively in all aspects of life that require Web interaction. In addition, it introduces visually impaired high-school students to research through participation. This work is funded by BCS, CISE, OCI, and EHR.

非视觉网络互动中固有的挑战阻止了200多万美国盲人有效地参与基于网络的日常活动。现有的文献并没有提供一个理解的认知和主观知觉的视障人士在这些情况下。没有这种理解，任何努力，以克服非视觉Web交互的挑战将不会充分知情。这个项目研究了盲人网络用户所采用的认知策略，这些策略与典型的视力正常的用户不同。 研究设计使用了一个问题解决框架来比较盲人参与者和视力正常的参与者在执行一系列基于网络的任务时如何“大声思考”。盲人参与者有困难的活动，从他们的言语证明，将进一步探讨，以确定他们的认知策略，以及他们如何不同于正常人使用的策略。网络交互对于许多日常活动都很重要，包括教育、工作、信息搜索、购物和社交。超过200万视力受损的美国人无法有效地参与这些活动。该项目的研究结果可能会形成干预措施的基础，使盲人能够克服挑战，有效地参与需要网络互动的生活的各个方面。此外，它还通过参与将视障高中生引入研究。 这项工作由BCS，CISE，OCI和EHR资助。
