摘      要：Understanding how certain engineering design factors influence users’ affective emotions is gaining attention in order to achieve better designs for high-end products. This study examines how to quantify users emotional satisfaction with the door-pulling operation. A series of pilot tests are conducted as follows: (1) an in-house developed force-stroke machine captures 132 door motions and reveals great reproducibility at 10mm/s with a 100mm displacement (r = 0.973);(2) the captured door motions are expressed as force-stroke curves (kgf on the y-axis, millimeters on the x-axis) to identify physical properties;(3) nine experts evaluate the doors’ overall operating sensitivity for the 132 latch-hook modules by using a 100mm visual analog scale, figuring out the proper spring force range (0.5-2kgf) and displacement range (5-11mm);(4) 23 semantic pairs collected from the nine experts describe the door-operating sensitivity;and (5) 30 participants rate the 23 semantic pairs based on a semantic differential scale while using the doors to identify primary affective factors. Factor analysis derives four semantic pairs: reaction intensity, softness, luxuriousness, and robustness. Based on them, the 30 participants evaluate the door-operating sensitivity for FORCE (latch spring force: 1kgf, 1.5kgf, 2kgf) and STROKE (stroke lengths: 5mm, 10mm, 15mm). Results show STROKE is a better predictor of emotional satisfaction and suggest a longer stroke length more evenly distributes the tension on the tender and elastic pulling load while opening the door. This property may give users more time to feel the overall operating sensitivity, especially for luxuriousness (which accounts for about 50% of the overall satisfaction). These results can be utilized to achieve better designs for high-end products that reflect users’ affective emotions. © 2023, The Authors. All rights reserved.
