The rare four-leaf clover (FLC) is regarded worldwide as a symbol of good luck. However, it is not easy to find one among the common three-leaf clovers. This study explores how people feel when technological intervention is introduced to assist in identifying FLC. We investigated user experiences during outdoor searches supported by an object detection algorithm. Our results showed no significant difference in the impact of technological intervention on users' positive emotions; however, the findings suggest that such intervention may play a supportive role.
