I tried building the scenes that came with the SDK and got the following error:
error CS1703: An assembly `Tobii.EyeX.Client.Net20′ with the same identity has already been imported. Consider removing one of the references
Assets/Tobii/Plugins/x86_64/Tobii.EyeX.Client.Net20.dll (Location of the symbol related to previous error)
Assets/Tobii/Plugins/x86/Tobii.EyeX.Client.Net20.dll (Location of the symbol related to previous error)
I’ve seen this problem from time to time. Usually it disappears after I’ve done the following: checked in the Inspector for the files above that one is set to 64 bit and the other to 32 bit, made sure build settings was set to PC, Mac & Linux Standalone – Target Platform: Windows, restarted Unity Editor.
We are working on an updated Unity SDK that will not have this problem. Would you be interested in a pre-release version of this SDK? I could e-mail it to the e-mail address registered with your login here.
Are you planning to make your eye Tracker enabled application/game available to many people? We hope so, and for this reason, we have done our best to make it easy for you to distribute your applications and games built using the Tobii SDKs.
When you download a Tobii SDK you agree to an SDK License Agreement that (with a few exceptions) allows you distribute the Tobii client library files necessary to add eye tracking to your application. One limitation is that you may only use the Tobii Core SDK to develop interactive applications. If you want to develop software for analytical purposes, post processing or aggregation of eye tracking data across multiple users, please Contact Tobii Pro. Also, you may not use the SDK to develop software that is used in so-called high-risk use applications.
We at Tobii also want to do our best to help you reach as many people as possible with your application, and help you to commercialize it if that is your goal. Contact us if you want to know more about what the opportunities will be for you during the current year, and how we expect the market for eye tracking in consumer electronics to evolve.
