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...

It has been proposed to use microwaves to beam down power to Earth from space based solar power stations in Geosynchronous Orbit. However the Rayleigh diffraction limited optics requires enormous antennas, typically a few kilometers in diameter, and huge power levels, of 5GW to 10GW. A much lower cost of entry investment (100x lower) is afforded by use of optical or infrared lasers with much sh...

Conversion between different grammar frameworks is of great importance to comparative performance analysis of the parsers developed based on them and to discover the essential nature of languages. This paper presents an approach that converts Combinatory Categorial Grammar (CCG) derivations to Penn Treebank (PTB) trees using a maximum entropy model. Compared with previous work, the presented te...

We propose a new approach to localizing handle-like grasp affordances in 3-D point clouds. The main idea is to identify a set of sufficient geometric conditions for the existence of a grasp affordance and to search the point cloud for neighborhoods that satisfy these conditions. Our goal is not to find all possible grasp affordances, but instead to develop a method of localizing important types...

We propose the use of perceived affordances to computationally model linguistic concepts in situated language use. Perceived affordances are mental structures that capture the relationship between the language user and the embedding situation. We employ computational models of human perceived affordances to understand situated language: language that dynamically depends on the current physical ...

El objetivo fue evaluar los pastos del género Urochloa: Mulato II, Convert 330 y 431 al variar las edades de corte en atributos: dinámica población tallos, recambio tejido, relación hoja:tallo, peso por tallo rendimiento materia seca. La investigación se realizó praderas Instituto Tecnológico Pinotepa, la localidad San José Estancia Grande, Oaxaca. Los tratamientos fueron genotipos: 431. datos ...

We propose situated affordances as an extension to the well known concept of affordances. Situated affordances extend affordances by taking the environmental context, in which an object is embedded, into account. We argue that the extended concept allows the learning of qualitatively more complex tasks. In this paper we report the conceptual result of ongoing work in which a cognitive robotic a...

Frequently physical affordances are considered one of the main advantages of tangible interfaces or input devices, making interaction intuitive. This assumption may be overly simplistic – because physical objects have a multitude of physical affordances and properties, it is difficult for the designer to restrict these to (only) those that match with the digital system that they are connected w...

Even though aesthetics and affordances are two important factors based on which designers provide effective ways of interaction through their artifacts, there is no study or theoretical model that relates these two aspects of design. We suggest a theoretical explanation that relates the underlying functionality of aesthetics, in particular, of interaction aesthetics and of affordances in the de...
