- W3080555220 abstract "In an effort to simplify human resource management and reduce operational costs, control towers are now increasingly designed to not be implanted directly on the airport but remotely. This concept, known as remote tower, offers a “digital”working context: the view on the runways is broadcast remotely using cameras located on site. Furthermore, this concept could be enhanced to the control of several airports simultaneously from one remote tower facility, by only one air traffic controller (multiple remote tower). These concepts offer designers the possibility to develop novel interaction forms. However, the most part of the current augmentations rely on sight, which is largely used and, therefore, is sometimes becoming overloaded. In this Ph.D. work, the design and the evaluation of new interaction techniques that rely onnon-visual human senses have been considered (e.g. hearing, touch and proprioception). Two experimental campaigns have been led to address specific use cases. These use cases have been identified during the design process by involving experts from the field, appearing relevant to controllers due to the criticality of the situation they define. These situations are a) poor visibility (heavy fog conditions, loss of video signal in remote context), b) unauthorized movements on ground (when pilots move their aircraft without having been previously cleared), c) runway incursion (which occurs when an aircraft crosses the holding point to enter the runway while another one is about to land), and d) how to deal with multiple calls associated to distinct radio frequencies coming from multiple airports. The first experimental campaign aimed at quantifying the contribution of a multimodal interaction technique based on spatial sound, kinaesthetic interaction and vibrotactile feedback to address the first use case of poor visibility conditions. The purpose was to enhance controllers’ perception and increase overall level of safety, by providing them a novel way to locate aircraft when they are deprived of their sight. 22 controllers have been involved in a laboratory task within a simulated environment.Objective and subjective results showed significantly higher performance in poor visibility using interactives patial sound coupled with vibrotactile feedback, which gave the participants notably higher accuracy in degraded visibility.Meanwhile, response times were significantly longer while remaining acceptably short considering the temporal aspect of the task. The goal of the second experimental campaign was to evaluate 3 other interaction modalities and feedback addressing 3 other critical situations, namely unauthorized movements on ground, runway incursion and calls from a secondary airport. We considered interactive spatial sound, tactile stimulation and body movements to design3 different interaction techniques and feedback. 16 controllers’ participated in an ecological experiment in which they were asked to control 1 or 2 airport(s) (Single Vs. Multiple operations), with augmentations activated or not. Having no neat results regarding the interaction modalities into multiple remote tower operations, behavioural results shown asignificant increase in overall participants’ performance when augmentation modalities were activated in single remotecontrol tower operations. The first campaign was the initial step in the development of a novel interaction technique that uses sound as a precise means of location. These two campaigns constituted the first steps for considering non-visual multimodal augmentations into remote tower operations." @default.
