An essential aspect in the evaluation of Virtual Training Environments (VTEs) is the assessment of users’ training success, preferably in real-time, e.g. to continuously adapt the training or to provide feedback. To achieve this, leveraging users’ behavioral data has been shown to be a valid option. Behavioral data include sensor data from eye trackers, head-mounted displays, and hand-held controllers, as well as semantic data like a ...

Scene graphs are nodes and edges consisting of objects and object-object relationships, respectively. Scene graph generation (SGG) aims to identify the objects and their relationships. We propose a bidirectional GRU (BiGRU) transformer network (BGT-Net) for the scene graph generation for images. This model implements novel object-object communication to enhance the object information using a BiGRU layer. Thus, the information of all objects ...
