Visualising Location Uncertainty to Support Navigation under Degraded GPS Signals

Examining Effort in 1D Uncertainty Communication Using Individual Differences in Working Memory and NASA-TLX

“…The NASA-TLX is suitable for visualization research because it can be conducted efficiently either online or in-person after a visualization task. Therefore, various HCI studies have used the NASA-TLX to examine applications that include uncertainty visualizations [9,[80][81][82]. Researchers found that street map applications that incorporate uncertainty visualizations require lower mental demand and effort than those without uncertainty [9], but did not find differences in task accuracy.…”

Using Computer Simulations to Investigate the Potential Performance of ‘A to B’ Routing Systems for People with Mobility Impairments

“…Navigation beyond accessibility: Navigation in the real world has been a long-standing topic of interest in the wider MobileHCI community, including the design of routing interfaces. The minimization of the risk of error is one such concern that arises in a range of circumstances, be it as-the-crow-flies navigation [38], missing GPS information (where there is a degraded signal) [5,34], or the provision of 'scenic' or more comfortable routes [21]. These types of problems could also benefit from the identification of street elements that likely contain problems, be it a lack of a scenic feature, an area that is likely to have degraded mobile or GPS signals, or have other features which make navigation more challenging.…”
