These data reveal the way smartphone usage patterns tend to be organized according to notification functions (mSNS, SMS), a specific set of technical cues that mediatize social demand and promote social connectedness. Users manage these cues through a recurrent trend composed of a three-step sequence: they often start by using applications displaying notifications; they favor those that display social demands; and, among them, they prioritize these relational solicitations in accordance with social status or types of relationships. By examining the distribution of users¡¯ attention between urban environments and smartphone applications, this video-ethnography also highlights how these ¡°checking habits¡± are organized according to a set of spatial cues and some daily commute characteristics, such as visual coordination with passengers in public transport. These technical cues mediatize a growing number of social demands that encourage users to keep their eyes focused on their smartphone¡¯s screen in public spaces. We argue that these technical cues create a temporary bubble effect and social isolation at a proximal scale, which mostly operate at the beginning of smartphone usage patterns %K connection cue %K mobile phone %K mobility %K social media %K usage pattern %U https://journals.sagepub.com/doi/full/10.1177/2050157917747642
