Perceiving possibilities for action-affordances-requires sensitivity, accuracy, and consistency. In the current study, we tested children of different ages (16-month-olds to 7-year-olds) and adults to examine the development of affordance perception for reaching through openings of various sizes. Using a psychophysical procedure, we estimated individual affordance functions to characterize part...

We review the psychological notion of affordances and examine it anew from a cognitive systems perspective. We distinguish between environmental affordances and their internal representation, choosing to focus on the latter. We consider issues that arise in representing mental affordances, using them to understand and generate plans, and learning them from experience. In each case, we present t...

Title of dissertation: From Form to Function: Detecting the Affordance of Tool Parts using Geometric Features and Material Cues Austin O. Myers, Doctor of Philosophy, 2016 Dissertation directed by: Professor Yiannis Aloimonos Department of Computer Science With recent advances in robotics, general purpose robots like Baxter are quickly becoming a reality. As robots begin to collaborate with hum...

The paper introduces the concept of affordance within frame semantics as a significant factor in the semantics/pragmatics boundary issue. Specifically, it is argued that expansions of literal meanings, which have been argued to be required for the complete interpretation of sentences, are constrained and guided by affordances, in contrast to the generally assumed complete freedom of the pragmat...

This study extends the learning and use of affordances on robots on two fronts. First, we use the very same affordance learning framework that was used for learning the affordances of inanimate things to learn social affordances, that is affordances whose existence requires the presence of humans. Second, we use the learned affordances for making multi-step plans. Specifically, an iCub humanoid...

To build theory about how to achieve expected benefits from a system implementation, we conducted a longitudinal study of the implementation of an electronic health record (EHR) system at a multi-site clinic using grounded theory methods and a critical realist perspective. We developed a mid-level process theory of how clinics actualize affordances arising from the implementation of an EHR. In ...

How do we know that a kitchen is a kitchen by looking? Relatively little is known about how we conceptualize and categorize different visual environments. Traditional models of visual perception posit that scene categorization is achieved through the recognition of a scene's objects, yet these models cannot account for mounting evidence that human observers are relatively insensitive to the loc...

The role of affordances In our opinion the model would be improved if affordance for action mechanisms were integrated: The potentiation of motor interactions consistent with the conventional use of a perceived tool (Bub et al., 2008). Affordances would easily explain the mechanism underlying the quick choice of the most appropriate tool when an action goal is given. In Figure 1A, bidirectional...

Knowledge needs to traverse through social and cognitive boundaries as it is transformed from information to innovation. Little is known, however, regarding what, if any, role various IT material constraints and affordances play in supporting multidisciplinary innovations involving the complexities of heterogeneous knowledge. The notion of affordance has been used in Human Computer Interaction ...
