New technologies and especially robotics is going towards more natural user interfaces. Works have been done in different modality of interaction such as sight (visual computing), and audio (speech and audio recognition) but some other modalities are still less researched. The touch modality is one of the less studied in HRI but could be valuable for(More)
This paper describes the participation of the the MRIM research Group of the LIG laboratory in the ImageCLEF scalable concept image annotation subtask 1. We made use of a classical framework to annotate the 500K images of this task: we tuned an existing Convolutional Neural Network model to learn the 251 concepts and to locate bounding boxes of such(More)
Pretend play is a storytelling technique, naturally used from very young ages, which relies on object substitution to represent the characters of the imagined story. We propose a system which assists the storyteller by generating a virtualized story from a recorded dialogue performed with 3D printed figurines. We capture the gestures and facial expressions(More)
This paper studies the problem of images indexing and retrieval related to museum visits. We especially focus on "offline" use of mobile devices (i.e., without connection to a remote server), from the point view of intrinsic quality and the point of view of mobile potential use. We describe three approaches, and we study their qualitative behavior on a test(More)
