On the surface, the talk appears to be about user engagement; however, it is actually about screen time addiction and social responsibility. I will start off by discussing common user engagement techniques, such as streaks, achievements, etc., and how they work. Then after this comes a pivot: a video compilation of users engrossed in their phones instead of engaging in their surroundings or companions. The talk then turns into a discussion of impacts that screen time addiction has on our users, and the role that we play as engineers. The talk finishes with practical approaches for ethical, healthier engagement.
