Traditionally, it has played a crucial role in fostering social bonds during in-person gatherings. However, in the realm of virtual and online meetings, the capacity for meaningful eye contact is often compromised by the limitations of the platforms we use. In response to this challenge, we present an application framework that leverages webcams to detect and share eye gaze attention among participants. Through the framework, we organized 13 group meetings involving a total of 43 participants. The results highlight that the inclusion of gaze attention can enrich interactive experiences and elevate engagement levels in online meetings. Additionally, our evaluation of two levels of gaze sharing schemes indicates that users predominantly favor viewing gaze attention directed toward themselves, as opposed to visualizing detailed attention, which tends to lead to distraction and information overload.},

Consequently, to develop agents that are able to navigate the social dynamics that accompany cooperative teamwork, evaluation criteria that refer only to objective task performance will not be sufficient. We propose perceived cooperativity and teaming perception as subjective metrics for investigating successful human-AI teaming.

As we shift to designing AI agents as teammates rather than tools, the social aspects of human-AI interaction become more pronounced. Consequently, to develop agents that are able to navigate the social dynamics that accompany cooperative teamwork, evaluation criteria that refer only to objective task performance will not be sufficient.

abstract = {User expectations impact the evaluation of new interactive systems. Elevated expectations may enhance the perceived effectiveness of interfaces in user studies, similar to a placebo effect observed in medical studies. To showcase the placebo effect, we executed a user study with 18 participants who conducted a reaction time test with two different computer screen refresh rates. Participants saw a stated screen refresh rate before every condition, which corresponded to the true refresh rate only in half of the conditions and was lower or higher in the other half. Results revealed successful priming, as participants believed in superior or inferior performance based on the narrative despite using the opposite refresh rate. Post-experiment questionnaires confirmed participants still held onto the initial narrative. Interestingly, the objective performance remained unchanged between both refresh rates. We discuss how study narratives can influence subjective measures and suggest strategies to mitigate placebo effects in user-centered study designs.},
