Researchers have developed a novel dual-stream Transformer architecture to automate the detection of mutual gaze and joint attention in dual-camera recordings. This new model utilizes frozen gaze-aware backbones and a custom token fusion mechanism to analyze the complex relational dynamics between individuals. Tested on caregiver-infant interactions, the system demonstrated superior performance compared to existing convolutional methods and a state-of-the-art multimodal LLM. The researchers have also released the model and its pre-trained weights to facilitate its use and fine-tuning by behavioral scientists. AI
