Displays

Hardware and software systems are growing everyday in scale and functionality. This increase in complexity increases the number of subtle errors. Moreover, some of these errors may cause catastrophic loss of money, time, or even in many cases human life. A major goal of ...

Scanned displays have potential for achieving high brightness and see-through configurations in many display applications. A MEMS- based solution based on these tradeoffs for SVGA level performance is presented, with test data illustrating optical, mechanical, and electrical performance. Comparison of this scanner against video requirements and other scanners previously reported are illustrated. The feasibility of MEMS-based scanners for Retinal Scanning Displays and other applications is discussed, with extension to higher video performance standards.

We present the design, implementation, deployment and evaluation of a novel urban computing infrastructure called UBI-hotspot. It is effectively a large interactive public display embedded with other computing resources. We have deployed a network of UBI-hotspots around downtown Oulu, Finland, to establish a public laboratory for conducting experimental ubiquitous computing research in authentic urban setting with diverse real users and with sufficient scale and time span. We focus on the first version of the UBI-hotspot which offers a wide range of services via different interaction modalities. We analyze the usage and user acceptance of the UBI-hotspots from qualitative and quantitative data collected over a period of eight months. Our first observations show that this type of infrastructure may be a useful addition to the urban space.

Imperfections in binocular image pairs can cause serious viewing discomfort. For example, in stereo vision systems eye strain is caused by unintentional mismatches between the left and right eye images (stereo imperfections). Head-mounted displays can induce eye strain due to optical misalignments. We have experimentally determined the level of (dis)comfort experienced by human observers viewing brief presentations of imperfect binocular image pairs. We used a wide range of binocular image imperfections that are representative for commonly encountered optical errors (spatial distortions: shifts, magnification, rotation, keystone), imperfect filters (photometric asymmetries: luminance, color, contrast, crosstalk), and stereoscopic disparities. The results show that nearly all binocular image asymmetries seriously reduce visual comfort if present in a large enough amount. From our data we estimate threshold values for the onset of discomfort. The database collected in this study allows a more accurate prediction of visual comfort from the specification of a given binocular viewing system. Being able to predict the level of visual discomfort from the specification of binocular viewing systems greatly helps the design and selection process. This paper provides the basis.

This paper describes a new software tool that addresses the deficiencies in the conventional text-based approach towards assembly language programming. The tool presents assembly codes in the form of hierarchical flow charts, whereby each layer ...

E-book reading devices open new possibilities in the field of reading. More activities than just reading a book can be performed with a single electronic device. For a long time, electronic reading devices have not been favored because their active LCD displays used to have a relatively low contrast. The new generation of electronic reading devices differs from earlier ones in the nature of the display: active LCD displays have been replaced with displays based on e-ink technology, which has display properties closer to that of printed paper. Moreover, e-ink technology has higher power efficiency, thereby increasing battery life and reducing weight. At first sight, the display looks similar to paper print, but the question remains whether the reading behavior also is equal to that of reading a printed book. In the present study, we analyzed and compared reading behavior on e-reader displays and on printed paper. The results suggest that the reading behavior on e-readers is indeed very similar to the reading behavior on print. Participants shared similar proportions of regressive saccades while reading on e-readers and print. Significant differences in fixation duration suggest that e-readers, in some situations, may even provide better legibility.► Reading behavior measured in eye movements on e-ink displays and print. ► Participants made significantly longer fixations when reading on a printed book. ► Participants made similar proportion of regressive saccades when reading on e-ink displays and print. ► Result shows that the reading behavior on e-ink-displays is very similar to the reading behavior on print. ► Overall the results suggest that the legibility of the current e-reader generation is good.

The relationships between the work products of a security engineering process can be hard to understand, even for persons with a strong technical background but little knowledge of security engineering. Market forces are driving software practitioners who are not security specialists to develop software that requires security features. When these practitioners develop software solutions without appropriate security-specific processes and models, they sometimes fail to produce effective solutions. We have adapted a proven object oriented modeling technique, use cases, to capture and analyze security requirements in a simple way. We call the adaptation an abuse case model. Its relationship to other security engineering work products is relatively simple, from a user perspective

Furniture market in India is predominantly an un-organized retail market (85%) but gradually with large scale organizations venturing into the sector has in turn the changed in behavior of consumers form dissonance reducing behavior to branding. This is possible by promotion strategies specifically branding adopted by large scale companies. Promotion is a strategy through which an individual or organization highlights the USP and benefits of a product or service to influence the buying behavior of the individuals. Promoting a brand is equally important as opening a store. Advertising, participation in exhibitions and e-marketing is perceived by retailers as a significant means to convey information to consumers. This study on promotional strategies is divided in three category advertising, participations in exhibitions and e marketing. The objective of the study is to compare the level of existing promotional strategies formulated by manufacturers & functional strategies adopted at retail level, to the consumer response to the above mentioned strategies. The study focuses on promotional efforts taken by retailers and compares it to requirements given by consumers for a better footfall in the outlet.
