dc.description.abstract | This study analysed natural press motions of the index, middle and ring fingers for ergonomic design of the positions and surface angles of the left, middle and right trackball buttons. Finger motions of 26 male participants for naturally pressing the trackball buttons were recorded after the participants adjusted the trackball buttons to their preferred locations for comfortable pressing. The natural positions of the finger pulps formed a symmetrically rainbow-shaped reach zone for the fingers. The natural press angles of the fingers’ motion trajectories to the vertical reference line ranged from 14.2° to 20.5°, suggesting an 18-degree surface from the horizontal line for the trackball buttons. Regression formulas (adjusted R 2 = 0.90 ± 0.07 and mean squared error = 8.55 ± 7.52 mm) were established to estimate the natural positions of finger pulps from hand segment lengths and joint angles for a population having different hand sizes from this study. Relevance to industry. Relevance to Industry: Trackball buttons designed based on the natural press motions of fingers can provide users with a low physical workload and a high comfort level. This study analysed the natural press motions of the index, middle and ring fingers for designing the positions and surface angles of trackball buttons. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. | - |
