Although landmarks are an integral part of navigation, they have rarely been used explicitly within electronic pedestrian navigation aids. We describe a two-part study into the use of landmarks in such aids, using a set of field experiments. The first part investigated whether such devices can be effective for older adults (over 60 years old), who might particularly benefit from them due to declines in sensory, cognitive and motor abilities. The second part compared the effectiveness of different methods of presenting landmark information. We show that a pedestrian navigation aid based around landmarks is particularly useful for older people and demonstrate that text, speech and photographs are all effective ways of presenting landmark information, although speech on its own has some drawbacks. We found that different people prefer information to be presented in different modalities, indicating a need for personalisation, although multimodality may also help to address this issue.

“…Chiasson, McGrath, and Rupert (2003) used three different rhythms to enlarge the 90-degree display resolution to indicate 30-degree segments. and McGrath et al (2004) used rhythm to indicate the amount of drift or the air speed in their helicopter hover displays, while Bosman, Groenendaal, Findlater, Visser, De Graaf, and Markopoulos (2003) found that length of pulse trains are a better coding than intensities in a guiding system for pedestrians.…”

SUPPLEMENTARY NOTES ABSTRACTThis study compared a tactile land navigation system to two operational systems with visual information displays. "Front end" workload and task analyses identified land navigation as having high and conflicting workload. The tactile display was expected to ameliorate the high visual and cognitive workload per Multiple Resource Theory (Wickens, 2002). Fifteen infantry Soldiers navigated three equivalent 1800-meter routes using each of three systems: (a) the personal tactile navigator (PTN) tactile system, (b) the U.S. Army precision lightweight GPS (global positioning system) receiver (PLGR), which is a hand-held GPS with an alpha-numeric display, and (c) the traditional compass system. Note: Each soldier traversed each lane with different navigation systems; we counterbalanced the order in which they used the systems and the lanes that were walked with each system in order to control for any effects attributable to order (such as fatigue) or to the lane itself.The PLGR system was predicted to enhance performance relative to the compass system because of reduced cognitive demands. The PTN system was predicted to enhance performance relative to both PLGR and compass systems because of (a) reduced cognitive demand from more intuitive display (e.g., following direction of tactor) and (b) off load from visual attention demand. Soldiers performed more quickly and accurately when using the PLGR and tactile systems, relative to a compass. However, there was no significant difference between GPS and tactile systems. This is likely because of the low need for focal visual attention during navigation in this experiment; there was not as much interference with the occasional use of a visual display. However, visual attention demand increa...

While driving many tasks compete for the attention of the user, mainly via the audio and visual channel. When designing systems depending upon providing feedback to users (e.g., navigation systems), it is a crucial prerequisite to minimize influence on and distraction from the driving task. This becomes even more important when designing systems for the use on motorbikes; space for output devices is scarce, as people are wearing helmets visual feedback is often difficult due to lighting conditions, and audio feedback is limited. In a first step we aimed at creating an understanding as to how information could be communicated in a meaningful way using vibrotactile signals. Therefore, we investigated suitable positions of actuators on the hand, appropriate length of the vibration stimulus, and different vibration patterns. We built a first prototype with 4 vibration actuators attached to the fingertips and asked 4 participants to test our prototype while driving. With this work we envision to lay the foundations for vibrotactile support in navigation systems.
