Abstract Drawing from the social capital framework and socioemotional selectivity theory, this study examines how individuals’ future time perspective (FTP) alters their processes, which further influences well-being. A two-wave survey was conducted across WeChat users possessing different FTPs. The findings showed that bonding bridging accumulation were attributed to differential affordances, ...

The purpose of this single-case study was to explore the lived experiences of a grade 6 teacher and students who used tablets as part of their classroom instruction. Malone and Lepper’s taxonomy of intrinsic motivations for learning is used as a framework for examining whether and how this particular theory of motivation applies equally well for mobile learning. This study reports on the grade ...

Humans demonstrate remarkable capabilities to use a variety of grasp strategies for a given object depending on the context of the task often referred to as grasp affordances in dexterous hands. The interplay among the nervous system, the morphology of the human hand, and the properties of the object to demonstrate these advanced grasp affordance skills are not well understood yet. A key hypoth...

The relation between energy consumption and its environmental impact is weak or even almost inexistent in the Brazilian scenario due to sociocultural reasons. This work takes advantage of an experimental smart grid deployment scenario to propose the concept of Social Eco-feedback Technology. It aims at establishing this relation by promoting a new social affordance (behavior pattern), favoring ...

LearningVillages (LV) is an online game-based virtual learning environment. It aims at facilitating elementary students to pursue social inquiry learning and hence attain collaborative knowledge building (CKB). LV operates in the form of massively multi-player online role-play gaming. Different villages in this “virtual world” represent different societal issues. To embark on the development of...

Localizing functional regions of objects or affordances is an important aspect of scene understanding. In this work, we cast the problem of affordance segmentation as that of semantic image segmentation. In order to explore various levels of supervision, we introduce a pixelannotated affordance dataset of 3090 images containing 9916 object instances with rich contextual information in terms of ...

We propose a new way to describe affordances for action. Previous characterizations of affordances treat action possibilities as binary categories-either possible or impossible-separated by a critical point. Here, we show that affordances are probabilistic functions, thus accounting for variability in motor performance. By measuring an affordance function, researchers can describe the likelihoo...

In the past decade, significant progress has been made in autonomous driving, and many novel computer vision methods have been proposed for vision-based autonomous driving. To date, most of these systems can be categorized into two major paradigms: mediated perception approaches and behavior reflex approaches. Mediated perception approaches [7] involve multiple sub-components for recognizing dr...
