31	Multi-Modal Technology for User Interface Analysis including Mental State Detection and Eye Tracking Analysis Husseini Orabi, Ahmed January 2017 (has links) We present a set of easy-to-use methods and tools to analyze human attention, behaviour, and physiological responses. A potential application of our work is evaluating user interfaces being used in a natural manner. Our approach is designed to be scalable and to work remotely on regular personal computers using expensive and noninvasive equipment. The data sources our tool processes are nonintrusive, and captured from video; i.e. eye tracking, and facial expressions. For video data retrieval, we use a basic webcam. We investigate combinations of observation modalities to detect and extract affective and mental states. Our tool provides a pipeline-based approach that 1) collects observational, data 2) incorporates and synchronizes the signal modality mentioned above, 3) detects users' affective and mental state, 4) records user interaction with applications and pinpoints the parts of the screen users are looking at, 5) analyzes and visualizes results. We describe the design, implementation, and validation of a novel multimodal signal fusion engine, Deep Temporal Credence Network (DTCN). The engine uses Deep Neural Networks to provide 1) a generative and probabilistic inference model, and 2) to handle multimodal data such that its performance does not degrade due to the absence of some modalities. We report on the recognition accuracy of basic emotions for each modality. Then, we evaluate our engine in terms of effectiveness of recognizing basic six emotions and six mental states, which are agreeing, concentrating, disagreeing, interested, thinking, and unsure. Our principal contributions include the implementation of a 1) multimodal signal fusion engine, 2) real time recognition of affective and primary mental states from nonintrusive and inexpensive modality, 3) novel mental state-based visualization techniques, 3D heatmaps, 3D scanpaths, and widget heatmaps that find parts of the user interface where users are perhaps unsure, annoyed, frustrated, or satisfied.

32	The Measure Of Meaning Pollon, Simon Carl January 2007 (has links) There exists a broad inclination among those who theorize about mental representation to assume that the meanings of linguistic units, like words, are going to be identical to, and work exactly like, mental representations, such as concepts. This has the effect of many theorists applying facts that seem to have been discovered about the meanings of linguistic units to mental representations. This is especially so for causal theories of content, which will be the primary exemplars here. It is the contention of this essay that this approach is mistaken. The influence of thinking about language and mental representation in this way has resulted in the adoption of certain positions by a broad swathe of theorists to the effect that the content of a concept is identical to the property in the world that the concept represents, and that because of this a concept only applies to an object in the world or it does not. The consequences of such commitments are what appear to be insoluble problems that arise when trying to account for, or explain, misrepresentation in cognitive systems. This essay presents the position that in order to actually account for misrepresentation, conceptual content must be understood as being very much like measurements, in that the application of a content to an object in the world is akin to measuring said object, and that conceptual content ought be understood as being graded in the same way that measurements are. On this view, then, concepts are the kinds of things that can be applied more, or less, accurately to particular objects in the world, and so are not identical to whatever it is that they represent.

And on the basis of them (after attempting to mapping out the network of their possible mutual influences, consequences, concurrency or filiations, in the interpretative part of the thesis, so on the II. to VI. chapter) try to define its final characteristics, periodisation, classification and his general definition. … and, moreover, or on the way to this purpose, perhaps to provide the reader a few other - perhaps more useful, or more interesting - information.
