Is it possible for humans to navigate in the natural environment wherein the path taken between various destinations is ‘optimal’ in some way? In the domain of optimization this challenge is traditionally framed as the “Traveling Salesman Problem” (TSP). What strategies and ecological considerations are plausible for human navigation? When given a twodimensional map-like presentation of the des...

This paper describes the systematic design method for Product-Service Systems (PSS) where service and product elements are integrated using affordances. In the PSS design method, a service element is composed of the activities from the service blueprint and the functions from the function analysis. The service elements contain the service providers and receivers and their activities and are to ...

Evidence from experiments with single objects indicates that perceiving objects leads to automatic extraction of affordances. Here we examined the influence of implied between-object actions on affordance processing. Images of task-irrelevant object pairs (e.g., a spoon and a bowl) were followed by imperative central targets. Participants made speeded left/right responses to targets, and the re...

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...

Abstract This work investigates how the concept of affordance should be revised following digital evolution. Starting from a review literature about affordance, most acknowledged constructs are compared with variegated definitions artefacts. The paper proposes definition overcoming inconsistencies identified in literature. study is enriched by series interviews to investigate final users' perce...

Mon-Williams and Bingham (2011) developed an affordance model of the spatial structure of reaches-to-grasp. With a single free parameter (P), the model predicted the safety margins (SMs) exhibited in maximum grasp apertures (MGAs), during the approach of a hand to a target object, as a function of an affordance measure of object size and a functional measure of hand size. An affordance analysis...

The present study aimed at determining whether and what factors affect the control of motor sequences related to interactions between conspecifics. Experiment 1 demonstrated that during interactions between conspecifics guided by the social intention of feeding, a social affordance was activated, which modified the kinematics of sequences constituted by reaching-grasping and placing. This was r...
