Assignment - view PDF and natively supported files by browsers embedded without Annotate PDF

Many teachers use the annotate PDF feature only to view the submitted work and grade without having to download it. In this context, using the "Annotate PDF" feature uses a considerable amount of storage and processing resources that could be avoided.

Assumptions:

• All modern browsers have a built-in PDF reader
• There is a growing list of file types supported natively by browsers (audio, video, image, PDF...)

Scenario A:

• The activity has been configured to allow the sending of files.
• The feedback type "feedback comments" is active.
• The "Annotate PDF" feedback type is inactive.

On the grader page, the teacher has the option of viewing the PDF and natively supported files by browsers in a modal window without downloading the file.

Scenario B:

• The activity was configured to accept only the sending of files.
• The maximum number of files allowed has been set to one.
• The accepted format it's an image natively supported by browsers.
• The feedback type "feedback comments" is active.
• The "Annotate PDF" feedback type is inactive.

When opening the grader page, the file is embedded in the browser on the left and on the right is displayed options for text comments, grade, etc. (Like to Annotate PDF but without PDF editing features.)

Scenario C:

• The activity was configured to accept only the sending of files.
• The maximum number of files allowed has been set to one.
• The accepted format is a video/audio type natively supported by browsers.
• The feedback type "feedback comments" is active.
• The "Annotate PDF" feedback type is inactive.

When opening the grader page, the video/audio is opened with player on the left and on the right is displayed options for text comments, grade, etc.
