Abstract—In this paper, we investigate the validity of Mixed Reality (MR) Simulation by conducting an experiment studying the effects of the visual realism of the simulated environment on various search tasks in Augmented Reality (AR). MR Simulation is a practical approach to conducting controlled and repeatable user experiments in MR, including AR. This approach uses a high-fidelity Virtual Reality (VR) display system to simulate a wide range of equal or lower fidelity displays from the MR continuum, for the express purpose of conducting user experiments. For the experiment, we created three virtual models of a real-world location, each with a different perceived level of visual realism. We designed and executed an AR experiment using the real-world location and repeated the experiment within VR using the three virtual models we created. The experiment looked into how fast users could search for both physical and virtual information that was present in the scene. Our experiment demonstrates the usefulness of MR Simulation and provides early evidence for the validity of MR Simulation with respect to AR search tasks performed in immersive VR.

Doctoral thesis from Darmstadt University of Technology. Title: Corporate lighting - Methods and techniques of architectural lighting for brand communication. Author: Thomas Schielke Presentation: Dissertation defense 4.3.2014. Online access to complete doctoral thesis: http://tuprints.ulb.tu-darmstadt.de/id/eprint/3466 Contact for correspondence: www.arclighting.de Abstract: This work analyses architectural lighting as an element of brand communication. The lighting is comprehended as the message of a sender, which has an impact on the appearance of architecture. In the context of experiments and case studies, the effects of lighting on the appearance will be examined for a neutral space and for interiors and exteriors in the retail and service sectors. Illuminance, luminance distribution, as well as the light spectrum and dynamic serve as independent variables of lighting. A model for the brand personality with the four factors of temperament, competence, attractiveness and naturalness will be drawn upon for the appearance as an independent variable, as well as a sociological model with the two factors of style and price for social milieus. The experiments are carried out in real space and using light simulations. The results provide correlations between the perception of brightness, contrast, colour temperature and colourfulness and the factors for the two models relating to the appearance. In individual cases models exist for predicting the appearance on the basis of the subjective evaluation of light. This work documents significant differences for both models with respect to the appearance due to an alteration of the light physics parameters of luminous intensity distribution and light spectrum. The economic analysis of the experiments did not result in any significant correlations between higher investment or operating costs and a correspondingly higher subjective price impression of the various lighting situations. Case studies on design guidelines for lighting prove the various lighting design and lighting technology strategies, as well as the processes in business practice. The semiotic analysis of case studies considers architectural lighting as symbol, the properties of the appearance as the object and the consumer as the interpretant, and discusses strengths and weaknesses in communication. In this way, the work produces a differentiated connection between architecture, lighting and marketing.

VR allows for an entirely new level of immersion, leading to more thrilling and engaging content to be delivered and is growing rapidly. Despite this, VR, especially on mobile, currently contains a number of limitations, which can make it an unrealistic, unconvincing and, sometimes, an uncomfortable experience. Virtual reality (VR) is a new way to deliver thrilling and engaging content and allows for a deep level of immersion. Despite this, VR, especially on mobile, currently has several limitations, which can make it an unrealistic, unconvincing and, sometimes, an uncomfortable experience. To achieve the true potential of VR, these limitations must be either solved or mitigated. Ways of mitigating these limitations include optimal alpha compositing approaches, texture filtering techniques and bump mapping methods for use with VR content. In these slides, technology company Arm will outline how to improve the rendering quality of your VR content, describing the most common pitfalls and bad practices, before providing clear examples and mitigation solutions of how to best overcome them.
