Multimodal Affect Recognition for Adaptive Intelligent Tutoring Systems.
Ruth Janning, Carlotta Schatten, Lars Schmidt-Thieme · 2014
The performance prediction and task sequencing in traditional adaptive intelligent tutoring systems needs information gained from expert and domain knowledge. In a former work a new efficient task sequencer based on a performance prediction system was presented, which only needs former performance information but not the expensive expert and domain knowledge. In this paper we aim to support this approach by automatically gained multimodal input like for instance speech input from the students. Our proposed approach extracts features from this multimodal input and applies to that features an automatic affect recognition method. The recognised affects shall finally be used to support the mentioned task sequencer and its performance prediction system. Consequently, in this paper we (1) propose a new approach for supporting task sequencing and performance prediction in adaptive intelligent tutoring systems by affect recognition applied to multimodal input, (2) present an analysis of appropriate features for affect recognition extracted from students speech input and show the suitability of the proposed features for affect recognition for adaptive intelligent tutoring systems, and (3) present a tool for data collection and labelling which helps to construct an appropriate data set for training the desired affect recognition approach.
