Grasp Sensing for Human-Computer Interaction
In Proceedings of the Fifth International Conference on Tangible and Embedded Interaction (TEI'11), Funchal, Madeira, Portugal, Jan. 2011 (bib)

The way we grasp an object depends on several factors, e.g. the intended goal or the handâs anatomy. Therefore, a grasp can convey meaningful information about its context. Inferring these factors from a grasp allows us to enhance interaction with grasp-sensitive objects. This paper highlights grasping as an important source of meaningful context for human-computer interaction and gives an overview of prior work from other disciplines. This paper offers a basis and framework for further research and discussion by proposing a descriptive model of meaning in grasps. The GRASP model combines five factors that determine how an object is grasped: goal, relationship between user and object, anatomy, setting, and properties of the object. The model is validated both from an epistemological perspective and by applying it to scenarios from related work.
