Can smartphone applications take the stress out of touring alone? Or will it take out the fun? And the discovery?
Imagine standing in the street of a foreign country and holding your smartphone out at arm's length, and having the names and uses of each building in front of you pop up on the screen -- along with info about the nearest metro station, store business hours and more. This type of application is actually pretty common these days. It uses a technology called augmented reality (AR), which is a live view of your real-world environment, captured on a screen and narrated by computer-generated input (usually text, but also graphics, sound and GPS data). It can be invaluable if you're touring where you can't make heads or tails of the language, or if you have a hopeless sense of direction. In other words, it can help you avoid getting lost, misunderstood, taken advantage of and other very stressful situations.
So what's involved in an AR device? The hardware usually consists of a processor, a display and sensors (all three of which are rolled into one unit and shaped to fit your hand) and the output device (usually a headset, which may not be necessary depending on how easy your display is to use). Standalone units were common at first, but more and more, smartphones and tablets have the camera, sensor and output needed to support AR. Consider the following AR can help you with:
- Identifying the full route of a bus you see down the street.
- Potential hazards in your path (such as poorly marked construction).
- Road conditions and traffic updates (if you are driving); and last but not least.
- Translating foreign text on signs and menus.
So why isn't everyone walking around with one on tour? Well, there are some definite drawbacks to using AR. Some that I can think of include:
Dangerous levels of immersion. You can get so absorbed in the interface that you become oblivious to your surroundings. AR will tell you a lot, but not about the bad habits of drivers, or the motivations of the people around you.
You can become dependent on AR. It can erode your observational skills, your intuition and your problem-solving skills. Consider the possible effect on your confidence, and your ability to guide others someday (like your kids!).
The application can take some of the discovery and personal experience out of your trip. If part of your touring enjoyment comes from figuring out whether you've just stumbled upon a great tattoo parlor or just a music store, or whether an odd building is a museum or an antiques shop, then think about saving AR for occasional use, when you're really stuck -- or opt to travel the "traditional way," with a map in your hand instead.
