“…The device was adapted from an existing one which had been used for studying driving postural comfort (Verriest and Alonzo, 1986;Ribouchon, 1991). The seat adjustments in height, tilt, fore-aft position as well as the steering-wheel height adjustment were motorized.…”

“…Reaching distance, control movements, and field of view (FOV) are restricted according to the body extensions (Verriest & Alonzo, 1986). These dimensions were evaluated using the one‐way criterion of the maximum design limit (limited by lower extreme value or 5th p), as shown in Figure 7.…”

“…The ergonomic characteristics of workspaces are primarily determined by the accommodating space clearance, visual needs, reaching distance, manipulative needs, and postural and biomechanical loads. This ergonomic need influences users to select a comfortable and functional workspace (Verriest & Alonzo, 1986). For practicing effective ergonomic workspace design, the 5th, 95th, or 5th–95th percentile ( p ) values of anthropometric variables (of users) are usually considered (Reed & Flannagan, 2000; Khaspuri et al, 2007).…”

Background and objective To ensure effective carrying, scouting, patrolling, and large‐scale combat operations, the workspace design of light armored vehicles (LAVs) should be compatible with anthropometry and range of motion (ROM) measurements of the soldiers. This study examines the extent of mismatch between the anthropometric dimensions of the Ethiopian army and existing workspace dimensions of the LAV. Predictive equations have been formulated for design dimensions considering anthropometry and ROM of the target population to avoid possible incompatibility. Method The assessment was conducted on three existing Ethiopian LAVs, and mathematical equations were framed to predict the vehicular design dimensions. Anthropometric and ROM data of Ethiopian soldiers (n = 310) from an earlier reported survey by the authors were utilized. The accommodation capacity of existing LAVs was evaluated using a one‐way or two‐way (mis)match criterion, based on individual workspace characteristics. Along with the predicted dimensions, key vehicular dimensions were compared with other globally accepted vehicular standard dimensions. Results Twenty‐two basic design dimensions that comply with ergonomics principles were proposed. A high mismatch (in terms of the accommodating capacities of the three LAVs) between the existing and predicted design dimensions indicates the incompatibility of the existing design dimensions in their accommodation of most Ethiopian army personnel. The predicted dimensions comply with different global vehicular standards, thus validating the results. Conclusion The research findings indicate that the incompatibilities between vehicular space dimensions and army personnel's anthropometry must be addressed to evade the adverse consequences on occupational health. The LAVs should be redesigned according to the anthropometry and ROM dimensions of Ethiopian soldiers.

“…The neutral angles have been identified in a number of ways, most notably by observing postures underwater and in zero-g environments (16), and by assuming that the average postures observed over a wide range of task conditions represent the preferred or neutral posture (13,15,17). The cost functions and optimization procedure, which are interdependent, have generally been parameterized a priori, using, for example, a minimization of the deviations from the neutral angles (13).…”
