Technology-facilitated “superpowers” are a popular topic in human-computer interaction, providing people with the experience of having superhero-like fantastic abilities. However, science fiction literature tells us that superpowers can also be unfortunate. We designed Wi-Fi Twinge, a system that uses electrical muscle stimulation to extend human perception to sense unseen Wi-Fi signals, giving people an allergy-like twinge reaction to Wi-Fi: a superpower that can be seen as unfortunate while also having potential benefits. Through an in-the-wild study, interviews with 12 participants revealed that although the superpower from Wi-Fi Twinge induced negative feelings and impacted certain day-to-day activities, it improved awareness of self and the surrounding environment. We used these results to offer design tactics for creating future superpower systems that consider potential unfortunate side effects. Ultimately, we aim to advance our understanding of technology-facilitated superpowers.
