Avionics, such as synthetic vision systems, head-up displays, and electronic flight bags, have been described as being "compelling" but such a description is not quantifiable, compellingness is a property of the display, that attracts attention (a cognitive behavior), at the expense of attention allocated to other tasks and to other displays, for a long duration of time. Compellingness can be beneficial; e.g., when attention is drawn to information when that information is time-critical (e.g., compelling alerts) or when information is presented in such a way that it reduces the "cost"; of accessing or integrating that information. However, compellingness may also have negative impacts, and such prolonged attention has been referred to attentional tunneling (to the physical world) or cognitive tunneling (to a single task relative to the array of tasks confronting the pilot). The purpose of this paper was to try to establish a link between the physical features of display compellingness and the manifestations of cognitive/attentional tunneling to identify features that lead to compellingness and gather metrics to define it.
