Automation technologies increasingly assist or augment human motor functions in contexts such as driving, surgery, and rehabilitation. As such systems become more prevalent, it is essential to understand how they influence users' subjective experience, particularly in social settings where individuals may compare themselves with others using more or less capable systems. Previous research has shown that automation can modulate the sense of agency (SoA), responsibility, and time perception, but these effects have mostly been examined in non-social contexts. In this study, we examined how automation and social context shape users’ sense of responsibility and temporal experience. Participants engaged in a continuous circle-tracing task using a trackpad-controlled cursor under two automation conditions: auto-correction and delay. In Experiment 1, participants performed the task alone. In Experiment 2, two social contexts were introduced: while observing another agent using the same system (social–matched), or a different system (social–mismatched). The results showed that the automation condition consistently influenced subjective control, performance, drawing speed and accuracy in both experiments, with better outcomes in the auto-correction condition. The social context had no effect on these indices. However, temporal reproduction and responsibility judgements exhibited different patterns in Experiment 2. Specifically, subjective time compression occurred in social conditions under delay, and responsibility ratings were highest when the observer used the same system, and lowest when they used a different one. These findings suggest that automation performance has a consistent influence on core aspects of task execution and self-evaluation, while social context selectively modulates higher-order, self-related experiences, such as responsibility attribution and time perception. These findings emphasize the importance of considering technological and social factors when evaluating user experience in semi-automated environments.
