In this paper, we report on our experiences investigating the role of digital technology in face-to-face instruction of students with intellectual disability. In this process, we used a multi-method approach and our findings integrate results from focus groups, interviews, observations, iterative prototyping, and user evaluation. Ultimately, we hope that our ...

Online subtitle databases allow users to easily find subtitle documents in multiple languages for thousands of films and TV series episodes. However, getting the subtitle document that gives satisfactory synchronization on the first attempt is like hitting the jackpot. The truth is that this process often involves a lot of ...

Creating compelling multimedia productions is a non-trivial problem. The problem is compounded when authors want to integrate community media assets: media fragments contributed by a potentially wide and anonymous recording community. In this paper, we report on a hybrid authoring approach that provides mixed support for automated creation and manual ...
