“…Thus it is strongly recommended for manufacturers/industry to adopt this highly useful tool and achieve financial gains by reducing cost on account of building physical prototypes and testing with real human beings. Further manufacturing/ marketing firms can reach out to potential buyers using virtual technology as a training/demonstration tool [18] regarding how to use their products and also giving gender, somatotypes specific instructions if any (where ergonomic compromise is inevitable) enabling them to make well judged buying decisions [19] for satisfying error free use. However during this study, it was found impossible to create manikins representing children and elderly populations as desired by authors.…”

Most of the shoe racks available in market are required to be in tune with ergonomic criteria to enhance their usability. Keeping this fact in mind, an attempt was initiated to design an ergonomic multipurpose shoe rack for a small family with 5-6 members of varying age group starting from kids to grandparents to suit present day apartment model residential dwellings. Following a small user survey and brain storming, it was decided that the intended design should be usable for all family members and all shoes in each rack to be visible for someone standing in front, easy to move, simplicity in use (taking shoes/socks, put on shoes, tying lace etc.), compact and aesthetically appealing. Protection from dust, availability of proper clearance dimensions and inclusion of safety aspects were also considered as added features. Following development of 3D-CAD model of desired shoe rack from concept sketching, various human factor aspects were evaluated in DELMIA software with digital manikins representing Indian anthropometric data to justify the design for Indian users. Present paper demonstrates virtual ergonomic evaluation process to confirm whether design of shoe rack would really be acceptable to targeted users and satisfy their need in real scenario. Readers are expected to visualize the simplicity of using digital human modeling tools for virtual ergonomic evaluations and thus advocate its use as and when required for diverse applications.

“…To quantify anatomical site‐specific UV exposure with respect to the direct, diffuse, and reflected components, we developed SimUVEx v2 , a numerical tool based on 3D graphic techniques and human modeling to estimate the exposure of a 3D virtual mannequin. Human modeling that combines technology with science is widely implemented in various fields such as medical treatment , surgery , ergonomics , film and television , and sports . Although several studies have addressed the human body exposure to UV , to the best of our knowledge, very limited efforts have been brought to the application of human modeling and 3D computer graphics for estimating and visualizing UV exposure .…”

Shade is an important means of protection against harmful effects of sun ultraviolet (UV) exposure, but not all shades are identically protective. UV rays scattered by the atmosphere and surroundings can reach the skin indirectly. To evaluate the relative contribution of the direct, diffuse, and reflected radiation in UV protection provided by different sizes of shade structure, we used SimUVEx v2, a numeric tool based on 3D graphic techniques and ambient ground UV irradiance. The relative UV exposure reduction was expressed by the predictive protection factor (PPF). Shade structures were found to predominantly reduce exposure from direct radiation (from 97.1% to 99.9% for the upper body areas such as the head and the neck), with greater protection from larger shade structures and structures closer above the subject. Legs were the least protected anatomical zone from any shade structure above the subject with PPF ranging from 18.5% to 68.1%. Throughout the day, except for lower solar zenith angles (SZA), small and high shade structures provide the lowest protection (between 20% and 50%), while small and low shade structure show PPF between 35% and 65% and large and high shade structures reach PPF higher than 60%.

“…These topics range from the realistic modeling of humans-their looks, texture, and skin deformation-to the more advanced topics of behavior, motion prediction, and cognitive aspects." Human modeling and simulation is now a mature field [15] [22] [23] and apart from the film industry, it has been successfully applied in a wide range of areas: training [25] , ergonomics [21] [24] [27] , medicine [26] , surgery [28] and many more [30] . Surprisingly, although a particular interest has been dedicated to the human body exposure to UV [33] [34] , very limited efforts have been brought to the application of human modeling and 3D Computer Graphics for estimating and visualizing exposure to irradiation in general [29] and to UV irradiation in particular [12] .…”

The research presented in this paper aims at developing and validating a predictive tool of individual exposure to solar UltraViolet (UV). UV exposure depends on ambient irradiation level and individual factors related to activity (position to the sun, clothing, duration of exposure, and other forms of sun protection). We predict exposure levels of body parts on basis of ambient irradiation levels and information about postural activity. The prediction system uses existing techniques in the field of 3D rendering to visually sketch an accurate estimation of the exposure distribution over body parts represented as a 3D triangular mesh. The results are compared against individual dosimetric measurements. Our approach is based on the similarities between our assumptions about the individual UV exposure model and the rendering of 3D computer generated scenes.
