Direct touch between people is a key element of social behaviour. Recently a number of researchers have explored games which sense aspects of such interpersonal touch to control interaction with a multiplayer computer game. In this paper, we describe a long term, in-the-wild study of a two-player arcade game which is controlled by gentle touching between the body parts of two players. We ran the game in a public videogame arcade for a year, and present a thematic analysis of 27 hours of gameplay session videos, organized under three top level themes: control of the system, interpersonal interaction within the game, and social interaction around the game. In addition, we provide a quantitative analysis of observed demographic differences in interpersonal touch behaviour. Finally, we use these results to present four design recommendations for use of interpersonal touch in games.

We present a study of how filmmakers collected and visualized physiological data—“biodata”—to construct a series of short promotional films depicting people undergoing “thrilling” experiences. Drawing on ethnographic studies of two major advertising campaigns, we highlight key concerns for integrating sensors and sensor data into film production. Our findings address the perceived benefits of using biodata within narratives; the nature of different on-screen representations of biodata; and the challenges presented when integrating biodata into production processes. Drawing on this, we reconsider the nature of information visualization in the filmmaking context. Further implications from our case studies provide recommendations for human--computer interaction (HCI) collaborations with filmmaking and broadcast industries, focusing both on the practical matters of fitting sensor technologies into and handling data within production workflows, as well as discussing the broader implications for managing the veracity of that data within professional media production.
