| 摘 要： |
This paper presents a methodology to evaluate the preference of the user in relation to the trigger of a rifle. The selected approach is based on a Jury Test methodology which is a well know assessment method used in several fields, such as the subjective perception of acoustic noise or sound evaluation. In this case, the subjective test is applied to the tactile perception of the user to the stimuli of the rifle trigger, thus exploiting the possible means of interaction the human has with the object of interest. This approach is really important to define a complete user experience, helping to reach an innovative vision in the design and development of the product. As the Jury Test collects subjective preferences given by the users, a methodology is presented to correlate objective indices to these subjective preferences. The correlation is performed considering different parameters of the rifle trigger, previously measured with a specific experimental campaign conducted on real rifles, using an elasticometer. A correlation analysis is presented to find the optimal values of the objective metrics in order to maximise the subjective preference. In particular the highest values of the preferences towards the rifle trigger are correlated to the parameter of the trigger force and displacement. Best values have been found to be low force applied to the trigger and low trigger displacement. This method proves therefore to be efficient in correlating the parameters of this application case providing quantifiable feedback on the product in the context of a User-Centred Design.
本文提出了一种评估用户对步枪扳机触发装置偏好性的方法。所选方法基于“陪审团测试”（Jury Test）技术，该方法在多个领域中已被广泛应用，例如主观噪声感知或声音评价等。在此研究中，通过将主观测试应用于用户对步枪扳机刺激的触觉感知，从而探索人类与目标对象之间可能的交互方式。这种方法对于定义完整的用户体验至关重要，有助于在产品设计与开发过程中实现创新理念。由于陪审团测试能够收集用户的主观偏好，因此本文还提出了一种将客观指标与这些主观偏好进行关联的方法。相关性分析基于使用弹性仪在真实步枪上开展的特定实验，测量了扳机不同参数的数值。最后，通过相关性分析确定最优的客观指标值，以最大化用户的主观偏好。特别是，对步枪扳机的偏好值最高时，与扳机力和位移参数呈正相关。研究发现，最佳数值表现为施加在扳机上的力较小且扳机位移较低。因此，该方法在关联此类应用参数方面表现出高效性，能够在以用户为中心的设计框架下，为产品提供可量化的反馈信息。 |
