Whether you’re travelling on a familiar journey such as to the shops, local supermarket or doctor, or whether you’re planning to travel further afield to a new city or even country, GPS navigation can help you get to where you want to go.
GPS navigation apps come in several different forms and are, for the most part, completely free.
GPS Navigation comes installed as standard on almost all smart phones. On an iPhone, “Apple Maps” is the built in GPS navigation tool. On Android “Google Maps” provides similar functionality. Both can give you verbal directions, show the route on a map which you can scroll through, and you can locate nearby points of interest along your route such as cash machines or public toilets.
If you are totally blind, you may find it useful to have additional information about your route. There are several apps which can help you plan journeys by aiding in the discovery of new locations and providing you with more in-depth information about your surroundings.
The Blind Square app allows you to know what is around you when you are walking down the road. It tells you what road you are on and the business and shops on each side of the road as you come near them. This is useful to know when you are passing the post office or nearing your destination.
Blind Square will work in the background and your phone can stay in your pocket. It is recommended that you have headphones or earphones that are comfortable but still allow you to hear what's happening around you as you are walking down the road. The Blind Square app is only available for iOS and currently costs £38.99.
Soundscape from Microsoft is a solution for iPhone only. It uses 3D stereo sound through a pair of headphones to create a virtual audio representation of your environment by playing tones and making announcements relative to your current position and location. For example, if you are walking along a street and a second street opens to your left and right as a crossing, the app will announce this, advise that the street continues ahead as well as to your right and left.
The Soundscape app also has functions to create beacons, as you approach a point of reference. An audio beacon can be played to indicate how close you are to that reference point and in which direction it lies.
Lazarillo is a free navigation app available for both Apple and Android devices. It is fully accessible using VoiceOver and Talkback. Lazarillo has an Around Me function that will tell you about nearby shops, cafes and other facilities and a Categories function that allows you to filter the sort of place that you are looking for and tells you the proximity and directions on foot, by car or using public transport.
There are many more apps that provide information in different formats. So finding the right app for your circumstance and experience level can go a long way in helping to ensure you become an effective navigator.
There are several considerations you need to be aware of when travelling with GPS.
Firstly, GPS is a guide only and should never be used as a replacement for a mobility aid such as a cane or guide dog. GPS can provide limited information about safe places to cross roads and not all crossings are marked. It can also be inconsistent and unreliable depending on where the tool is getting the information from.
GPS is accurate within approximately five to 30 metres depending on several factors including the signal of your phone and the ability to receive information from overhead satellites. Therefore, you need to use your own mobility skills to identify the exact positioning of doorways, locations to buildings and so on.
GPS also uses satellite technology to find your position and because of this, will drain your device battery quickly. Make sure you have enough charge in your battery when using GPS. Make sure that you are connected to the internet at all times and have enough data on your plan.
