EAGER: The Mind of the Blind on the Web

非视觉网络互动的固有挑战阻碍了200多万美国盲人有效地参与常规的基于网络的活动。现有的文献没有提供对视障人士在这些情况下的认知和主观知觉的理解。如果没有这种理解，任何克服非可视化Web交互的挑战的努力都不会得到充分的了解。这个项目考察了盲人网络用户使用的认知策略，这些用户与典型的有视力的用户不同。这项研究设计使用了一个问题解决框架来比较盲人参与者和有视力的参与者在执行一系列基于网络的任务时“大声思考”的方式。盲人参与者有困难的活动将被进一步探索，以确定他们的认知策略以及它们与有视力的人使用的策略有何不同。网络互动对许多日常活动都很重要，包括教育、工作、寻找信息、购物和社交。超过200万的视障美国人无法有效地参与这些活动。这一项目的结果可能成为干预措施的基础，使盲人能够克服挑战，有效参与需要网络互动的生活的方方面面。此外，还介绍了视障高中生通过参与进行研究。这项工作得到了BCS、CESE、OCI和EHR的资助。

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.
