在日常生活活动中收集的手的所有自由度的运动捕获仍然具有挑战性。仪表式手套是一个有吸引力的选择，因为它们更易于使用。然而，特定对象的手套校准需要很长时间，而且对残疾人士来说也有局限性。在这里，提出了一种校准程序，包括只记录一个简单的手位置，以便即使在严重受伤的情况下，也可以在日常生活活动中捕获16个手关节的运动学。通过对6名受试者进行详细的特定于受试者的校准，在多天内重复三次的44次登记中获得的平均收益，获得了“跨受试者的收益”。在另外4名受试者中，比较了应用“跨受试者校准”或特定受试者校准所产生的关节角度。与详细的、特定于受试者的方案相比，与“跨受试者校准”相关的全局误差很小(偏差：0.49°；精度：4.45°)，与多天重复同一受试者的详细方案所产生的误差(0.36°；3.50°)相当。此外，在一个受试者中，将“跨受试者校准”的性能直接与另一种快速校准方法进行了比较，后者以视频测量协议为黄金标准，产生了更好的结果。
Motion capture of all degrees of freedom of the hand collected during performance of daily living activities remains challenging. Instrumented gloves are an attractive option because of their higher ease of use. However, subject-specific calibration of gloves is lengthy and has limitations for individuals with disabilities. Here, a calibration procedure is presented, consisting in the recording of just a simple hand position so as to allow capture of the kinematics of 16 hand joints during daily life activities even in case of severe injured hands. ‘across-subject gains’ were obtained by averaging the gains obtained from a detailed subject-specific calibration involving 44 registrations that was repeated three times on multiple days to 6 subjects. In additional 4 subjects, joint angles that resulted from applying the ‘across-subject calibration’ or the subject-specific calibration were compared. Global errors associated with the ‘across-subject calibration’ relative to the detailed, subject-specific protocol were small (bias: 0.49°; precision: 4.45°) and comparable to those that resulted from repeating the detailed protocol with the same subject on multiple days (0.36°; 3.50°). Furthermore, in one subject, performance of the ‘across-subject calibration’ was directly compared to another fast calibration method, expressed relative to a videogrammetric protocol as a gold-standard, yielding better results.
