We present an algorithm for computing the relative perceptual saliencies of the features of a three-dimensional object using either goodness-of-view scores measured at several viewpoints or perceptual similarities among several object views. This technique addresses the inverse, ill-posed version of the direct problem of predicting goodness-of-view scores or viewpoint similarities when the obje...

Multidimensional signal detection theory is a multivariate extension of signal detection theory that makes two fundamental assumptions, namely that every mental state is noisy and that every action requires a decision. The most widely studied version is known as general recognition theory (GRT). General recognition theory assumes that the percept on each trial can be modeled as a random sample ...

This paper describes technology and tools for Intelligent HCI (IHCI) where human cognitive, perceptual, motor, and affective factors are modeled and used to adapt the H C interface. Intelligent HCI emphasizes that human behavior encompasses both apparent human behavior and the hidden mental state behind behavioral performance. IHCI expands on the interpretation of human activities, known as W4 ...

While the debate about whether AI, robots, or machines will replace humans is raging (among Gates, Hawking, Musk, Thiel, and others), there remains a long tradition of viewpoints that take a progressively more human-centric view of computing. A range of viewpoints from machine-centric to human-centric computing have been put forward by McCarthy (intelligent machines) [JM07], Weiser (ubiquitous ...

We describe work to control graphics ren­ dering under limited computational resources by taking a decision-theoretic perspective on perceptual costs and computational savings of approximations. The work extends earlier work on the control of rendering by introduc­ ing methods and models for computing the expected cost associated with degradations of scene components. The expected cost is com­ ...

Objectives: Paper and pencil exercises are extensively used to enhance children’s visual perceptual skills, while exercises involving volumetric shapes have been neglected. The present study aimed to develop a combined training package, including volumetric shapes and paper and pencil exercises, and to investigate its effectiveness in strengthening the visual perceptual skills of preschool chil...

one of the main features of high throughput computing systems is the availability of high power processing resources. cloud computing systems can offer these features through concepts like pay-per-use and quality of service (qos) over the internet. many applications in cloud computing are represented by workflows. quality of service is one of the most important challenges in the context of sche...

In Chapter 1 and throughout this book , we describe a large number of models , each different in detail-each a variation on the parallel distributed processing (PDP) idea. These various models, and indeed many in the literature , clearly have many features in common , but they are just as clearly distinct models. How can we characterize the general model of which these specific models are insta...

This paper explores a concept of sketch-based informal user interface for graphic computing, which can be characterized by two properties: strokebased input and perceptual processing of strokes. A sketch-based graphics input prototype system designed for creative brainstorming in conceptual design is introduced. Two core technologies for implementing such a system, adaptive sketch recognition a...
