Hand-object interactions (HOI) feature regularly in our daily activities in which we use one hand or two to manipulate objects directly or to use various tools. Through HOI, humans excel in manipulation tasks, master new skills, and adapt to complex and continuously changing environments. Recently, there is a surge of interest in understanding and generating hand-object interaction, to support applications in robotics, augmented reality, and other important fields. Such applications usually require a detail
The key goal of this workshop is to assemble experts in 4D vision, hand-object interaction, dexterous manipulation, and animation synthesis to synchronize and coordinate the efforts. First of all, the workshop would help researchers working on 4D HOI understanding to know about dexterous manipulation and tailor their research topics toward interaction-oriented 4D understanding. Secondly, embodied AI researchers could improve their understanding of the limitation of current 4D HOI perception and design their
We have invited a few leading researchers with extensive related experience to make keynote presentations at our workshop. We will also organize a competition to benchmark the current progress of 4D HOI geometric understanding and to also encourage more researchers to join the field. We will organize a panel discussion at the conclusion of our full-day workshop. We envision that such discussions will inspire people and stimulate novel research for 4D hand-object interaction.
