The emotional response a person has to a living space is predominantly affected by light, color and texture as space-making elements. In order to verify whether this phenomenon could be replicated in a simulated environment, we conducted a user study in a six-sided projected immersive display that utilized equivalent design attributes of brightness, color and texture in order to assess to which extent the emotional response in a simulated environment is affected by the same parameters affecting real environments. Since emotional response depends upon the context, we evaluated the emotional responses of two groups of users: inactive (passive) and active (performing a typical daily activity). The results from the perceptual study generated data from which design principles for a virtual living space are articulated. Such a space, as an alternative to expensive built dwellings, could potentially support new, minimalist lifestyles of occupants, defined as the neo-nomads, aligned with their work experience in the digital domain through the generation of emotional experiences of spaces. Data from the experiments confirmed the hypothesis that perceivable emotional aspects of real-world spaces could be successfully generated through simulation of design attributes in the virtual space. The subjective response to the virtual space was consistent with corresponding responses from real-world color and brightness emotional perception. Our data could serve the virtual reality (VR) community in its attempt to conceive of further applications of virtual spaces for well-defined activities.

This paper presents a successful application of fuzzy logic in the design of an interactive control system for an architectural living space. Fuzzy logic is applied in order to process subjective perceptual data based upon aesthetic considerations. In the interactively modifiable living space, occupants can generate various sensory-perceptive spatial qualities with affective dimensions in real time. This is accomplished by modifying one or more design parameters of color, brightness, texture, and material in order to meet the emotional, psychological, proprioceptive and aesthetic needs associated with daily living. The human-space interaction is perception-based. It is structured around a set of aesthetic guidelines formulated from correlations that measure the extent to which each design parameter impacts user perception. Fuzzy logic system implements the aesthetic guidelines as fuzzy control rules in the analysis. It allows for processing non-numerical, linguistic data in order to modify appropriate design parameters and produce spatial outputs that are meaningful and effective for the occupants.

The objective of the presented work was to develop, characterize and evaluate the biodegradable, proactive, protective, novel active packaging blend films of low methoxy pectin and sodium alginate and identify their antimicrobial and antioxidant ability with plant-based natural phytochemicals like cinnamaldehyde. Different blend films were prepared in different ratio like (75% pectin ± 25% sodium alginate) (100% pure pectin), (100% pure sodium alginate), (100% Pectin+200µL cinnamaldehyde), 75% pectin+25 sodium alginate+700µL cinnamaldehyde), The antimicrobial activity was tested against foodborne pathogens E. coliO157:H7 (MTCC 90), and Salmonella Typhi (MTCC 733) and zone of inhibition were recorded. On the basis of linear correlation analysis (R2), the free radical scavenging activity of 10% bio-composite incorporated with 0.30% cinnamaldehyde blends was 0.9235 for DPPH scavengers where citric acid were used as a positive control. The film was characterized by TGA, DSC, FTIR, and XRD analysis result was shown a significant effect on thermal behavior.
