Abstract
Achieving high precision and efficiency is pivotal in a laboratory environment to ensure the seamless progression of experiments. This study delves into the realm of laboratory user experience, focusing on chip assembly in typical lab setting. Our objective is to unravel the effects of varying assembly point indicator colors and lighting conditions on user productivity and comfort. A total of 28 participants were recruited and divided into two groups. One group worked with assembly points that had green edges, while the other worked without this color cue. We explored eight distinct hues (black, white, red, yellow, blue, green, purple, cyan) as variables. After receiving training in chip assembly, participants were tasked with completing eight chip assembly tasks independently and rating their comfort level following each task. An eye tracker measured the time taken to complete each assembly. The data revealed that, except for black (target point without color, average completion time of 3.56s), the completion times for the other seven hues ranged between 2.6s to 2.8s. This implies that while indicator colors under 2000lux lighting boost identification efficiency, the specific hue of these indicators has no significant effect on assembly efficiency. In terms of user comfort ratings, the presence of green color at the assembly point’s edge made the green the most comfortable color, with white ranking third. In the absence of green edges, green fell to sixth in comfort, yet white consistently remained in third place. Other colors did not show significant pattern in comfort scores. This indicates that user comfort is more closely related to the inherent color of the product and the assembly point indicators. The impact of color around the assembly point on user comfort is minimized when white is used as the indicator color.This study provides valuable insights into the influence of lighting and indicator colors on efficiency and comfort in a laboratory setting, contributing to the design of future laboratory products for enhanced user experience and efficiency
