The Multimodal Spatial Description Corpus
The Multimodal Spatial Descriptions
When describing spatial scenes not in the situated environment, humans often describe the scenes with natural language, at the same time complement the verbal descriptions by “placing” the non-visible landmarks in gesture space. To decode such multimodal descriptions, one must interpret speech and gestures in parallel, fuse information from both modalities and build a mental representation of the description. We provide a data set to model the decoding task. The data set provides audio and video recordings of natural scene descriptions, hand motion data tracked by a Leap sensor, as well as manual transcriptions of verbal descriptions and annotations of deictic gestures.
We designed a simplified task to elicit multimodal descriptions. For each description, a scece composed of two circles and a square was shown to the participant on a screen. Participants were instructed to describe the scenes in their own way, as long as mentioning the colour, shape, size and spatial relations of the objects.
In total, the data set includes recordings from 14 native German speakers. To provide some feedback to the participants and create some impression of interactivity (rather than of making a passive recording), after each description a score was shown on the screen, ostensibly reflecting the degree of understanding of an automated system ( In reality, the score was given by a confederate who had the instruction to reward when all attribute types were mentioned).
A detailed description of the resource and a baseline model of real-time understanding of multimodal scene descriptions can be found in the associated paper.
The original spatial scenes, hand motion data, audio transcriptions and deictic gesture annotations can be downloaded here.
