Seven Theses on the Future of Smart Glasses
Seven Theses on the Future of Smart Glasses A trend analysis of the future of smart glasses in retail “Kapitelnavn” | Seven Theses on the future of Smart Glasses | Synoptik-Fonden side 1 ISBN: 978-87-93300-07-1 This trend report was funded by the Synoptik Foundation and carried out by Brian Due. Published as: CIRCD reports of social interaction, 1(4), 1-34, Centre of Interaction Research and Communications Design, Uni- Executive summary This report shows that opticians and people with interests in the eyeglass business need to be ready to understand, assist with and even sell smart glasses within the next five to seven years. On the background of an analysis based on research, papers, news stories, interviews and surveys, seven theses about the technological devel- opment and nearby future of smart glasses are proposed. The report shows that: • Today’s smart glasses are similar to the first versions of smartphones. But technological development is exponential and smart glasses will soon be mainstream. However, not as widely adopted as smartphones. • Google Glass is an icebreaker product and other products are following in the slipstream. There are already many different smart glass products on the market and on a prototy- pe level. All the big IT companies and many startups are already producing and/or have patents for new products. • Early adopters will start using smart glasses in three years and the early majority in five to seven years. • In terms of use and design, smart glasses will be divided into two types: 1) glasses for industrial, health and fitness purposes that will have many functionalities and thus a more computerized and sporty design, and 2) glasses for the ordinary consumer that will look more like ordinary glasses with fashionable designs. -

A Defence of Separatism
A Defence of Separatism by Boyd Millar A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Philosophy University of Toronto © Copyright by Boyd Millar (2010) A Defence of Separatism Boyd Millar Doctor of Philosophy Graduate Department of Philosophy University of Toronto 2010 Abstract Philosophers commonly distinguish between an experience’s intentional content—what the experience represents—and its phenomenal character—what the experience is like for the subject. Separatism —the view that the intentional content and phenomenal character of an experience are independent of one another in the sense that neither determines the other—was once widely held. In recent years, however, separatism has become increasingly marginalized; at present, most philosophers who work on the issue agree that there must be some kind of necessary connection between an experience’s intentional content and phenomenal character. In contrast with the current consensus, I believe that a particular form of separatism remains the most plausible view of the relationship between an experience’s intentional content and phenomenal character. Accordingly, in this thesis I explain and defend a view that I call “moderate separatism.” The view is “moderate” in that the separatist claim is restricted to a particular class of phenomenal properties: I do not maintain that all the phenomenal properties instantiated by an experience are independent of that experience’s intentional content but only that this is true of the sensory qualities instantiated by that experience. I argue for moderate separatism by appealing to examples of ordinary experiences where sensory qualities and intentional content come apart. -

Symmetric Networks with Geometric Constraints As Models of Visual Illusions
S S symmetry Article Symmetric Networks with Geometric Constraints as Models of Visual Illusions Ian Stewart 1,*,† and Martin Golubitsky 2,† 1 Mathematics Institute, University of Warwick, Coventry CV4 7AL, UK 2 Department of Mathematics, Ohio State University, Columbus, OH 43210, USA; [email protected] * Correspondence: [email protected] † These authors contributed equally to this work. Received: 17 May 2019; Accepted: 13 June 2019; Published: 16 June 2019 Abstract: Multistable illusions occur when the visual system interprets the same image in two different ways. We model illusions using dynamic systems based on Wilson networks, which detect combinations of levels of attributes of the image. In most examples presented here, the network has symmetry, which is vital to the analysis of the dynamics. We assume that the visual system has previously learned that certain combinations are geometrically consistent or inconsistent, and model this knowledge by adding suitable excitatory and inhibitory connections between attribute levels. We first discuss 4-node networks for the Necker cube and the rabbit/duck illusion. The main results analyze a more elaborate model for the Necker cube, a 16-node Wilson network whose nodes represent alternative orientations of specific segments of the image. Symmetric Hopf bifurcation is used to show that a small list of natural local geometric consistency conditions leads to alternation between two global percepts: cubes in two different orientations. The model also predicts brief transitional states in which the percept involves impossible rectangles analogous to the Penrose triangle. A tristable illusion generalizing the Necker cube is modelled in a similar manner. -
