TagIT: supporting blind and partially sighted students by tagging images

Help us test TagIT, a crowdsourcing system to create image tags which will be used to create image descriptions to improve access to online teaching materials for blind and partially sighted students.

Online teaching materials contain many images. Some of these images are only decoration. However, many images are important to understanding the material and being able to learn it. Blind and partially sighted students are not be able to learn effectively if they do not know what is in the images, but lecturers do not have time to provide an explicit explanation of every image they use in their teaching materials.

The TagIT application allows people to easily tag images. These tags will help sighted students who are attending the same course with blind and partially sighted students to provide descriptions of the images used in the teaching materials. Participating in this project will improve your skills in tagging which will make your blog articles, YouTube videos and images easy to find by search engines. Following our image tagging tips will help you learn how to provide good image tags.

Tips To Help You Tag Images:

What is the content of the image: Create simple descriptions by putting what you can see in the image. This can be done by breaking the image down into its basic components. Bear in mind that your tags will be used by students to create more detailed descriptions so you do not have to be overly specific. You can use the information provided with each image to create tags.

Keep your tags relevant to the image content: Keep your tags directly related to the image content. Do not throw in random keywords as this can be considered as tag spamming.

Keep your tags short: Tags are keywords and should ideally be one or two words each.

Avoid words with multiple meanings: words with multiple meanings can be confusing, so if you use one extend your tag to add the right meaning (e.g. the word “Bank” it can mean the land alongside or sloping down to a river (“willows lined the bank”) or lake or a slope, mass, or mound of a particular substance (“a bank of clouds”).

Multiple tags: you can add as much tags as you wish as long as they are relevant to the content of the image.

Here is an example of a set of tags for an image to help you (this is not necessarily a perfect set of tags, but will give you an idea of what might be useful)
