Will they use it? Will it be useful? In-Situ Evaluation of a Tactile Car Finder.
When we develop new technology, we want to know if it will have the potential to be successful in the real world. This is not trivial! People may sincerely enjoy our technology when we expose them to it in a lab- or a field study. They may perform better than with previous solutions at the […]
Digital Helpers for the Blind
Last year, the WDR (German TV broadcaster) together our HaptiMap project partner GeoMobile tested the the PocketNavigator with Mr. Schmidt who is visually impaired. Actually, the PocketNavigator was not designed for blind users, since it only gives very coarse directions (straight, left, right, behind) via vibration patterns. However, to my surprise, Mr. Schmidt seemed to […]
Vibration-enhanced Paper Map Navigation
Maps are one of the oldest known information artifacts. An even in the times of GPS navigation systems, people still use them to find their ways in unknown environments. One of the challenges when navigating by a map is that the map’s abstract content has to be matched to the traveler’s environment. It has for […]
A Tactile Compass for Eyes-free Pedestrian Navigation
The idea came up when I was heading back to the hotel from a conference dinner at MobileHCI 2008 in Amsterdam. I had no orientation. The only guide I had was a map on my Nokia phone. Not being familiar with Amsterdam, the route let me right through the busy areas of the city center. […]
Turn-by-Turn Navigation – the Best Way to Guide Pedestrians?
Pedestrian navigation systems increasingly offer turn-by-turn instructions to guide travellers to their destinations. Turn-by-turn instructions, however, render the human’s inherent navigation skills redundant and lead to a worse understanding of the travelled route. Recently, researchers have increasingly studied providing general directional cues only, so travellers only get a sense of the direction, in which the destination lies, but have to find the route by themselves. This new paradigm may help to reengage travellers in a positive way.
