The normal, natural troubles of driving with GPS

In-car GPS based satellite navigation systems are now a common part of driving, providing turn-by-turn navigation instructions on smartphones, portable units or in-car dash-board navigation systems. This paper uses interactional analysis of video data from fifteen naturalistically recorded journeys with GPS to understand the navigational practices deployed by drivers and passengers. The paper documents five types of ‘trouble ’ where GPS systems cause issues and confusion for drivers around: destinations, routes, maps & sensors, timing and relevance and legality. The paper argues that to design GPS systems better we need to move beyond the notion of a docile driver who follows GPS command blindly, to a better understanding of how drivers, passengers and GPS systems work together. We develop this in discuss-ing how technology might better support ‘instructed action’

Driver’s Distraction and Understandability of Using GPS Navigation

GPS navigation is available on smartphone application providing turn-by-turn navigation instruction on smartphones and the distraction from GPS usage while driving also became an issue. In this paper, we present the strategy to mitigate the level of distraction by manipulating the type of display visual (2D and 3D) and placement (right, steer and left). We conducted field experiments in left-hand real traffic with 12 subjects. Our result illustrated that 3D conditions implied much fewer frequency of eye glances (FOG) than 2D conditions. Furthermore, steer conditions has much higher FOG than right and left placement conditions, but we found no significant effects on the ease of understanding (EOU) for visual display difference and the number of error for all conditions

Designing for frustration and disputes in the family car

This article appears with the express permission of the publisher, IGI Global.Families spend an increasing amount of time in the car carrying out a number of activities including driving to work, caring for children and co-ordinating drop-offs and pickups. While families travelling in cars may face stress from difficult road conditions, they are also likely to be frustrated by coordinating a number of activities and resolving disputes within the confined space of car. A rising number of in-car infotainment and driver-assistance systems aim to help reduce the stress from outside the vehicle and improve the experience of driving but may fail to address sources of stress from within the car. From ethnographic studies of family car journeys, we examine the work of parents in managing multiple stresses while driving, along with the challenges of distractions from media use in the car. Keeping these family extracts as a focus for analysis, we draw out some design considerations that help build on the observations from our empirical work.Microsoft Research and the Dorothy Hodgkin Awar

’Eyes free’ in-car assistance: parent and child passenger collaboration during phone calls

This paper examines routine family car journeys, looking specifically at how passengers assist during a mobile telephone call while the drivers address the competing demands of handling the vehicle, interacting with various artefacts and controls in the cabin, and engage in co-located and remote conversations while navigating through busy city roads. Based on an analysis of video fragments, we see how drivers and child passengers form their conversations and requests around the call so as to be meaningful and paced to the demands, knowledge and abilities of their cooccupants, and how the conditions of the road and emergent traffic are oriented to and negotiated in the context of the social interaction that they exist alongside. The study provides implications for the design of car-based collaborative media and considers how hands- and eyesfree natural interfaces could be tailored to the complexity of activities in the car and on the road

Taking iPhone Seriously: Epistemic Technologies and the Extended Mind

David Chalmers thinks his iPhone exemplifies the extended mind thesis by meeting the criteria ‎that he and Andy Clark established in their well-known 1998 paper. Andy Clark agrees. We take ‎this proposal seriously, evaluating the case of the GPS-enabled smartphone as a potential mind ‎extender. We argue that the “trust and glue” criteria enumerated by Clark and Chalmers are ‎incompatible with both the epistemic responsibilities that accompany everyday activities and the ‎practices of trust that enable users to discharge them. Prospects for revision of the original ‎criteria are dim. We therefore call for a rejection of the trust criterion and a reevaluation of the ‎extended mind thesis.

Perception of Disease Risk and Vulnerability as a Function of Proximity to National Park Boundaries in East Africa

Studies suggest households closest to parks and protected areas (PAs) are more likely to sustain park-related losses, but the relationship between human sickness and PAs has not been fully explored. Existing literature primarily focuses on human-wildlife conflicts (i.e. crop raiding) and the potential for zoonotic disease spillover and emergence at the human-livestock-wildlife interface at PA boundaries. Understanding local perceptions of disease risk and vulnerability is essential for assessing human health relative to conservation areas. This understanding will promote better-informed consideration of human health impacts in decision making for conservation. Data from surveys taken at 301 households around Kibale National Park (KNP), an important conservation area, were used to identify risk perception and factors influencing perceived disease risk and vulnerability. Human sickness was the most frequently cited worry by respondents (88%) and malaria was the most frequently cited illness (80.1 %). Those living closer to PAs may be at greater risk for park-related harm and cited more frequent cases of malaria and non-malarial fever. The perception of high risk for human sickness is pervasive across the region independent of household distance to the park and actual disease risk

Predefining regionalised environments for assisted navigation : does incorporating regions into navigation instructions assist a user’s spatial understanding of the environment they aretravelling through?

Dissertation submitted in partial fulfilment of the requirements for the degree of Master of Science in Geospatial TechnologiesThis thesis proposes introducing pre-defined regionalised areas into navigation instructions to allow drivers to learn more about the environment they’re travelling through. Following detailed navigation instructions, drivers are no longer required to learn about and understand their environment, which leaves drivers reliant on these navigation devices. An experiment using a virtual environment was conducted to evaluate if a group with additional regional instructions would complete tasks more effectively than a group with traditional instructions. While the regional group performed better on all accounts, statistically significant results were only found in three of ten variables. There were however, large differences in task completion rates, suggesting that incorporating pre-defined regions to navigation instructions does make a difference in drivers’ understanding of their environment
