The concept of affordances has been suggested as a way to understand the effects of information technology (IT) on human behavior and the factors that affect individual IT use. However research has discussed affordances mostly on a conceptual or theoretical level. We empirically investigate different characteristics of affordances to understand the factors that influence users’ understanding of...

Sitting too much is unhealthy, but a widespread habit in many societies. Realizing behavioral change in this area is hard. Our societies promote being seated via the way its places are structured: they are filled with chairs for example. How can we make healthier environments that invite people to move around more? This article shows how philosophical research in the area of embodied/enactive c...

Recently, object affordances have moved into the focus of researchers in computer vision. Affordances describe how an object can be used by a specific agent. This additional information on the purpose of an object is used to augment the classification process. With the herein proposed approach we aim at bringing affordances and object classification closer together by proposing fine-grained aff...

Given that a user interface interacts with users, a critical factor to be considered in improving the usability of an e-learning user interface is user-friendliness. Affordances enable users to more easily approach and engage in learning tasks because they strengthen positive, activating emotions. However, most studies on affordances limit themselves to an examination of the affordance attribut...

We address the problem of predicting affordances for dense 3D geometry scans of real-world scenes. Using an RGBD camera setup we observe people interacting with objects and learn the correlation between body part positions and interacted geometry. We encode this information as affordance maps over 3D geometry and predict affordances for novel scenes where no observations are available.
