The type of project you can submit
You have a clear idea in mind about the end result and the end user of the application. In that case the students will get the ball rolling during oSoc.
You have pretty solid idea, but it still requires some finetuning. You might be uncertain about the feasibility of a certain idea, concept or solution. In this case the students can provide some clarity by providing a new proof of concept. The students will exercise some creative freedom and will spend some time ideating.
No specific guidelines or preferences? You might want the #oSoc experience, but you’re not sure about the expected end result. You're at the right address. Let the students surprise you with their creativity, enthusiasm and skills! The students will take it from here.
