Information about multisensory perception and brain cognition mechanism lead to a better virtual world creation. Brain store visual and auditory information to use in predicting future events. Image memory takes information from visual clues which during speech recognition happens by recording visual information and its auditory mappings. Based on this process, brain create prediction mechanism for future events. In speech recognition brain record sound and its visual presentation. When brain encounter difficulty in perception an auditory stimulus, it looks for visual mappings to guess the result. Considering the fact that some completely unrelated similarity may exist, some mapping may not lead to better understanding the world around. When previous information misleads the brain to understand the situation cognitive biases happen. McGurk Effect discusses how different lip movements affect auditory perception to get disparate information. Variety of factors influence amount of dependency on visual clues. Tracking speaking, especially in challenging environments, can be increased by visual clues such as face expressions, tongue and lips movements. Considering these elements in virtual world and game designing lead to improving believability. Perception processes, brain nature, designing factors, graphical elements, and visual structures are discussed to find out improved ways in designing realistic auditory and visual components.Thesis (M.S.) -- Graduate School of Informatics.

Combining ability and heritability of selected rice varieties for grain yield, its components and grain quality characters

This study was conducted to determine the combining ability and heritability of rice grain yield, its components and some grain quality traits such as amylose content (AC), gelatinization temperature (GT), gel consistency (GC) and head rice recovery (HRR). The study was commenced by crossing the selected rice varieties based on a full diallel mating design. The F1 was harvested at the end of the season. In the following season, the crossed, reciprocal and parental lines were planted in randomly complete block design with three replications. Analysis of variance indicated that genotypes were significantly different for all traits. The diallel analysis by Griffing`s method showed highly significant differences for GCA for number of panicles per plant (PN), amylose content, gelatinization temperature and head rice recovery. Highly significant differences were also observed for both SCA and REC for all evaluated characters. The results showed that the grain yield (GY), number of filled grains (FGN), 100-grain weight (HGW) and GC were controlled by non-additive gene action, while the inheritance of PN, AC, GT and HRR were largely controlled by additive gene effects, although non- additive genetic components and reciprocal effect were also involved, which suggest that a selection process could be done in the early generations. The two improved lines (RI18442-1 and RI18430-46) were found to be good general combiners for GY and FGN, while the best combiners for PN was Tarom Mohali and IR50 and for HGW was RI18430-46. The best combinations for GY were RI18430-46 × IR50, Tarom Mohali × RI18447-2 and Daylamani × RI18430-46. The good hybrids were Tarom Mohali × IR50, Line23 × RI18447-2 and Line23 × Backcross line for AC. Narrow sense heritability showed that the GY and GC had the lowest values while the other traits had either moderate or high heritability, which indicates selection in the early generations could be done to fix the favorable genes. In present study, narrow sense heritability was high for AC and moderate for GT, PN and HRR

Multisensory Integration of Audiovisual Information in Avatar Faces: An Experimental Investigation of McGurk Effect

The McGurk effect is a multisensory phenomenon, an audiovisual illusion that shows how speech sounds may interfere with the visual sense. In case of an incongruency between a speech sound and a human face articulating the speech sound, human interlocutors tend to perceive an audiovisual percept different from the sound percept and the visual percept. For example, if the speech sound is ba and the visual presentation of the articulation is fa, human interlocutors usually perceive a third sound, va. What can we learn about audiovisual integration using an avatar face? To what extent do we observe the McGurk effect? The present study reports an empirical investigation that tested the extent of the effect in an avatar face designed for the purpose of the study. Our findings suggest that systematic patterns may obtained from the analysis of a specific avatar face, designed for the purpose of the study. The results also reveal the potential use of avatar designs for evaluating the impact of avatar designs on human multisensory integration by employing human responses to audiovisual illusions on avatar faces
