Novel photo‐aligned LC‐polymer compensation film for wide‐view TN displays

Abstract— We demonstrate a novel TN‐display compensation film with excellent contrast and minimal color shift, meeting the requirements for avionics displays. The film configuration was identified via extensive computer modeling. The experimental implementation based on ROLIC's LPP/LCP (linearly photopolymerizable polymer/liquid‐crystal polymer) technology results in excellent agreement with theoretical predictions.     

“TV no longer commands our full attention”: Effects of second-screen viewing and task relevance on cognitive load and learning from news

Second-screen viewing—the use of smartphones, tablets, and laptops while watching television—has increased dramatically in the last few years. Using multiple resource theory and threaded cognition theory, this study investigated the effects of second-screen viewing on cognitive load, factual recall and comprehension of news. Second, we examined the effects of relevant (i.e., looking up information related to the news story) and irrelevant (i.e., looking up information unrelated to the story) second-screen viewing on learning from news. Results from an experiment (N = 85) showed that second-screen viewing led to lower factual recall and comprehension of news content than single-screen viewing. These effects were mediated by cognitive load: second-screen viewing led to a higher cognitive load than single-screen viewing, with higher cognitive load, in turn, leading towards lower factual recall and comprehension of news content. Contrary to our expectations, we found no statistically significant differences between effects of relevant and irrelevant second-screen viewing.     

Coregistration of eye movements and EEG in natural reading: Analyses and review.

Brain-electric correlates of reading have traditionally been studied with word-by-word presentation, a condition that eliminates important aspects of the normal reading process and precludes direct comparisons between neural activity and oculomotor behavior. In the present study, we investigated effects of word predictability on eye movements (EM) and fixation-related brain potentials (FRPs) during natural sentence reading. Electroencephalogram (EEG) and EM (via video-based eye tracking) were recorded simultaneously while subjects read heterogeneous German sentences, moving their eyes freely over the text. FRPs were time-locked to first-pass reading fixations and analyzed according to the cloze probability of the currently fixated word. We replicated robust effects of word predictability on EMs and the N400 component in FRPs. The data were then used to model the relation among fixation duration, gaze duration, and N400 amplitude, and to trace the time course of EEG effects relative to effects in EM behavior. In an extended Methodological Discussion section, we review 4 technical and data-analytical problems that need to be addressed when FRPs are recorded in free-viewing situations (such as reading, visual search, or scene perception) and propose solutions. Results suggest that EEG recordings during normal vision are feasible and useful to consolidate findings from EEG and eye-tracking studies.

Improving the display performance of reflective color LCDs with micro-cone-structure film

Abstract— A micro-cone-structure film was proposed to improve the viewing angle of reflective color LCDs, both in chromaticity and brightness. The simulation results show that the film works as a collimating layer when the light is incident from the bottom side of cone and as a scattering layer when the light is incident from the tip side. The viewing-angle dependence of reflective interference color filters (RICF) is weakened dramatically by including such a film. The film is not only useful to RICF, but also to most reflective color LCD modes.     

Extremely broadband and wide‐angle retardation films

Abstract— The design and construction of retardation films with any desired dispersion properties is reported. The method is simple and requires only conventional uniaxial retardation films. As an example, the design of retardation films which have constant retardation over the entire visible spectrum is demonstrated. The design methodology will be given. Specific design examples for broadband achromatic quarter‐wave and half‐wave retardation films are disclosed. These films show almost no wavelength dependence even at large viewing angles.     

Longitudinal relations between children's exposure to TV violence and their aggressive and violent behavior in young adulthood: 1977-1992.

Although the relation between TV-violence viewing and aggression in childhood has been clearly demonstrated, only a few studies have examined this relation from childhood to adulthood, and these studies of children growing up in the 1960s reported significant relations only for boys. The current study examines the longitudinal relations between TV-violence viewing at ages 6 to 10 and adult aggressive behavior about 15 years later for a sample growing up in the 1970s and 1980s. Follow-up archival data (N=450) and interview data (N=329) reveal that childhood exposure to media violence predicts young adult aggressive behavior for both males and females. Identification with aggressive TV characters and perceived realism of TV violence also predict later aggression. These relations persist even when the effects of socioeconomic status, intellectual ability, and a variety of parenting factors are controlled.

Categorization of Japanese TV Viewers Based on Program Genres They Watch

Although programpreferences can be characterized on the basis of demographic attributes like sex, age or occupation or by taking the cultural studies approach focused on ethnic or social traits, preferences for programs often differ among people of the same sex, age, occupation and social class. We think that nothing can describe subjects’ viewing preferences more accurately than what programs they had watched in the past. To verify our hypothesis, we surveyed the viewing behavior of more than 1,600 randomly chosen individuals, and utilized this data to analyze people’s program choices. We categorized the respondents by the similarity of the programs they had watched and examined the groupings that emerged and the features of these groups.From our analysis, it became clear that a ‘more/less serious’ and ‘more/less fictional’ axes are involved in program selection.Our results show that eight groups (stereotypes) explain viewers’ contact with television, their motivation for choosing programs to watch, and their interest in matters other than television. Applying these stereotypes to the process of program selection or recommendation will be useful for the future design of personalized adaptive systems.
