Method and systems for modifying content of an electronic learning system for vision deficient users
A computer-implemented method for modifying one or more contents of an electronic learning system for a user impaired by a colour vision deficiency. The method includes: generating a vision profile for the user, the vision profile indicating at least a type of the colour vision deficiency, identifying, from the one or more contents, a content to be modified, the content including at least two portions formed of a first colour and a second colour, respectively, the first colour being different from the second colour but the first colour being at least partially indistinguishable from the second colour by the user due to the colour vision deficiency, identifying a content transformation to be applied to the content based on the vision profile, the content transformation including one or more adjustments of the content to accommodate the colour vision deficiency impairing the user; and applying the content transformation to the content.
1 . A computer-implemented method for assessing content for an electronic learning system, the method comprising:
receiving content data from a content creator, the content data being used to generate the content;
determining whether the content is deficient, the content being deficient when at least two portions of the content are formed of a first colour and a second colour, respectively, the first colour being different from the second colour but, to an individual impaired by a colour vision deficiency, the first colour being at least partially indistinguishable from the second colour, wherein determining whether the content is deficient comprises generating a vision profile of a user based on a weighted evaluation of results from at least two different vision tests, wherein a test result is assigned a weight according to a reliability factor for detecting a distinct colour vision deficiency; and
in response to determining the content is deficient, advising the content creator of the deficient content.
2 . The method of claim 1 , wherein advising the content creator of the deficient content comprises:
providing a replacement content for the deficient content, the replacement content being formed of one or more colours distinguishable by the individual impaired by the colour vision deficiency.
3 . The method of claim 2 , wherein the replacement content is selected from one of an alternative content and a modified content.
4 . The method of claim 1 , wherein advising the content creator of the deficient content comprises:
providing a version of the content, the version of the content representing how the content is perceived by the individual impaired by the colour vision deficiency.
5 . The method of claim 1 , wherein:
the content comprises, at least, course content for a course being provided to a group of students, the group of students including one or more students; and
the step of determining whether the content is deficient comprises:
identifying, from the group of students, any student impaired by the colour vision deficiency; and
in response to identifying at least one student is impaired by the colour vision deficiency, indicating the content is deficient if the content is deficient for the at least one student but otherwise, indicating the content is not deficient.
6 . A system for assessing content for an electronic learning system, the system comprising:
an interface module for receiving content data from a content creator, the content data being used to generate the content; and
a hardware processor in electronic communication with the interface module, the hardware processor being configured to:
determine whether the content is deficient, the content being deficient when at least two portions of the content are formed of a first colour and a second colour, respectively, the first colour being different from the second colour but, to an individual impaired by a colour vision deficiency, the first colour being at least partially indistinguishable from the second colour, wherein determining whether the content is deficient comprises generating a vision profile of a user based on a weighted evaluation of results from at least two different vision tests, wherein a test result is assigned a weight according to a reliability factor for detecting a distinct colour vision deficiency; and
in response to determining the content is deficient, advise the content creator of the deficient content.
7 . The system of claim 6 , wherein advising the content creator of the deficient content comprises:
providing a replacement content for the deficient content, the replacement content being formed of one or more colours distinguishable by the individual impaired by the colour vision deficiency.
8 . The system of claim 7 , wherein the replacement content is selected from one of an alternative content and a modified content.
9 . The system of claim 6 , wherein the hardware processor is configured to:
provide a version of the content, the version of the content representing how the content is perceived by the individual impaired by the colour vision deficiency.
10 . The system of claim 6 , wherein:
the content comprises, at least, course content for a course being provided to a group of students, the group of students including one or more students; and
the hardware processor is configured to:
identify, from the group of students, any student impaired by the colour vision deficiency; and
in response to identifying at least one student is impaired by the colour vision deficiency, indicate the content is deficient if the content is deficient for the at least one student but otherwise, indicate the content is not deficient.
