Abstract
In 1996, a preliminary study was initiated to explore the feasibility of using computer controlled digital cameras as a means of acquiring accurate anthropometric data on an automated basis. This system underwent several stages of development that culminated in a commercially available system known as the BoSS XXI (Body Scanning System). Validation studies of the BoSS XXI system's predecessor (the Intelligent Clothing and Equipment Sizing System (ICESS) indicated that the accuracy and precision of the direct linear measurements were sufficiently high to extend the use of this technology to seated posture measurements. The first development iteration demonstrated the feasibility of performing sitting posture measurements using the BoSS XXI technology, but the performance of some algorithms, namely those used for locating the eyes, was found to be less than satisfactory. The problems identified in that attempt were solved in a second iteration, as demonstrated by the results published in this report. The validation study involved 53 subjects: 28 males, 25 females. Manual and automated measurements of sitting height, eye height sitting, acromial height sitting, knee height sitting, and buttock-knee length were compared. The results showed that the correlation between expert manual measurement and the automated measurements was greater than 0.95 for all variables, and that the MAD ranged from 4 to 8 mm, which was within the maximum allowable measurement error for all but one vari
