Ach so! is designed to lower the barrier for using video to capture learning and to record events that others could use for learning. It aims to introduce these as useful practices at construction and training sites. Ach so! provides an app to introduce the process of using videos for learning.
The tool is for recording and annotating video clips for learning in construction. It is implemented as an app for Android platform, to be used with tablet computers or smartphones in construction sites or training sites. In ‘Ach so!’, the users record short example videos in four genres, ‘Site overview’, ‘Problem’, `Good work` and ‘Trick of trade’. Depending on genre, there is semantic information gathered to help finding and suggesting useful video clips for learners.
Videos can be connected to real world objects by linking them to nearby QR-code or barcode, or by finding videos recorded near current location.
