What are the different stimuli that can be uploaded in Affect Lab campaigns?

Depending on the use-case for the campaign, users have the option of uploading images, videos, or website links as stimuli for their campaign. The different stimuli formats, depending on the campaign use-case, are: 

• For a Media Insights Campaign, users can either upload a URL for the video or upload an actual video/image from their systems.

• File types supported: .mp4, .mov, Youtube public URL, Vimeo public URL
• File Size: 100 MB
• Supported Media Duration of all video files put together: 10 Minutes
• Eye Tracking accuracy will grade down for longer media duration. Recommend breaking it down into multiple tests.
• For a Shopper Insights Campaign, users need to select the type of stimuli in question (2D Pack, 2D Shelf, Virtual Shelf, Interactive Shelf, etc.) and either upload a high definition image or (in the case of the virtual shelf and interactive shelf) build it in the platform itself.

  • For a UX Insights Campaign, users have the option of either uploading the URL for a website/prototype or the prototype file itself. Users also need to specify tasks for the website/prototype which is then performed by respondents while their eye-tracking and facial coding data are recorded.

1. Max. number of prototypes that can be tested: 10
2. Formats supported: mix of prototype files and URLs
