Detection of a user's visual impairment based on user inputs or device settings, and presentation of a website-related data for sighted or visually-impaired users based on those inputs or settings

摘要

A data processing device is connected to a web data providing unit that provides web data via a network. The web data has at least one of first web data and second web data corresponding to the first web data. A screen reader can be installed on the data processing device. The displaying unit displays the web data. The screen reader voices the first web data displayed on the displaying unit and fails to voice the second web data displayed on the displaying unit. The acquiring unit acquires the web data from the web data providing unit. The determining unit determines, based on visually impaired information indicating that the user is a visually impaired, whether or not the acquiring unit should acquire the first web data from the web data providing unit even if the user instructs the acquiring unit to acquire the second web data from the web data providing unit.
