Where Are You? Mobile Apps For Finding Family and People at Risk

For a long time we have been encouraging our business partners to look at developing applications and devices to track elderly people, people with memory impaired conditions such as dementia, blind, autistic and others. There have been many challenges in this area because these devices are often a little on the bulky side and need daily charging due to the power constraints of batteries used for communications and GPS. Designing devices that are appealing such as bracelets, necklaces that people are prepared to wear has been a challenge. That development goes on and we hope that in the next year or so, we will see some success and demand from the market.

There is of course another huge market segment where mobiles are used. We are starting to see a number of applications like Pingbot, which we mentioned on our Facebook Page. This uses location based services including GPS to identify the location of a person’s mobile, with their permission of course. Effectively with Pingbot, the owner of the mobile has a secret word, effectively like a password that the user can share with those trusted people who may need to be able to find them. Obvious users would be children (most teenage children would not go anywhere without a mobile today), people with some form of disability, injury or medical risk, such as allergies or requiring medication, they may have forgotten to take with them. It could also be a social, sport or other reason for people to be able to find each other, such as a buddy finder environment. The idea of Pingbot is that all you need to do is send an SMS message with the secret word in order to find the location of that person.

GeoSmart has the web services and API’s to help developers create these types of solution in New Zealand and Australia. This includes highly accurate mapping, accurate turn by turn directions via the fastest route and services such as Reverse GeoCoding, which allows you to send a set of coordinates to our servers, which will return the nearest street address to that location.

These sorts of applications were difficult to market in the past because most people didn’t have mobiles with GPS. Today is a different story. It’s almost difficult to find a mobile in a retail store today that does not have GPS. We’d like to hear from developers who would like to help find that child that didn’t get home, the diabetic who went out without their insulin, or the blind person who has become disoriented. We offer a Developer Agreement for free and are local, in your time zone, with real people you can talk to about your application development.

What Tools Do You Need to Develop a Mobile LBS Application Part 4

A key component and possibly the second highest webmap query on the Internet is for Driving Directions and this has even more relevance in a mobile scenario. Driving Directions is a key point of difference for GeoSmart in New Zealand. In many other countries, the government provides free or low cost map data of a very high quality and suitable for car navigation and other purposes. In New Zealand this isn’t the case. The LINZ maps are the official datum for cadastral property boundaries. However, their road centreline is derived by a computation of the property boundaries.

As I’ve previously mentioned, New Zealand was town planned in Edinborough in the late 1800’s and many of the roads they draughted were never formed or constructed. They are known as paper roads. These roads exist on paper and on the LINZ map data used by services such as Google Maps, but they physically don’t exist. An example is Threepwood Road in Otago. If you have a look on the hybrid mode of satellite view and map view on Google, you will see that while the road exists on the map data, it physcially isn’t there in the satellite photography. This would cause a real problem if you wanted to go for a drive on it.

When GeoSmart discovered this problem and realised that, while it didn’t matter a lot for printed maps where you still have to analyse the data and make a decision on where you drive yourself, practically speaking, if you used either car navigation or a printed set of directions and couldn’t see a map as such, paper roads could cause a lot of confusion and grief. With LINZ having the only full maps of New Zealand, we decided we had to make our own maps. To do this we drove almost every road in New Zealand and also used a lot of Orthophotography to develop a driven road centreline, eliminating all paper roads and at the same time creating an accurate road centreline.

While collecting this data, we were also able to collect information such as the intersections controls (roundabouts, traffic lights etc), turn restrictions (one way streets, no left turns), speed zones, whether the road was sealed, accuracy of street signs and much more. We were even able to establish things like the angles of corners and inclination of roads (how steep they are etc).

This enabled us to build the car navigation dataset used by all the major brands including TomTom, Navman, BMW, Ford, Siemens VDO etc. It also allowed us to create sites like AA Maps and provide the API’s used on Wises web site. Now you can go to AA Maps, plan your journey and print out turn by turn directions from anywhere in NZ to anywhere in NZ and be confident that the instructions will work.

So, from there to your mobile. The Directions Web Service will work on any device that can identify a start point and where the user wants to go. The User Interface is up to the developer  and will probably vary from phone to phone because of its controls and screen size. For example a touch screen such as that on the iPhone or Windows Mobile, would have functionality closer to a web page, whereas a phone without a touch screen would have to function differently. That is really just a design issue, not a significant barrier.

If your phone has GPS or the ability to use cell tower triangulation, it will know where it is. But it is also possible (if you know) to tell your mobile where you are and where you want to go This could be an address you want to get directions to, or it could be Points of Interest from our POI Web Service mentioned in Part 2 of this series. Once you know the start and end of your journey, you can use the Directions web service to guide people directly to your desired location.

So now you can have turn by turn directions delivered to your phone. This could be send as an SMS with text directions, it could be an MMS combining text directions with an image of the route map, or an image zoomed in to your destination, or it could be information in your mobiles web or WAP browser, with enanced functionality.

Here’s the thing. If you are at home or in the office, you can use your PC, but it is of no use to you in your car or away from the computer. You may not know where you are going to want to go until you are out on the road. An LBS application with the Directions Web Service can give you the same freedom, without the necessity of interpreting a map, or more commonly the map isn’t there when you need it. Pick up the kids, meet someone for coffee, find your way from the car park to the show. All easy to do with LBS.

Just as a footnote, a few days ago a 62 year old woman set of from Christchurch to her  home on the West Coast of the South Island. She didn’t arrive and her friends and family spent a couple of days searching for her after she crashed her car down a 5 metre embankment. She was eventually found but the story could have been very different. She may not have been found at all, or not until it was too late to save her life, or she could have been found very easily. If she had a mobile with GPS, after she had been reported missing, if the phone was within coverage, it could have been called and located using an LBS service using GeoSmart tools and her searchers could have had turn by turn directions on their mobiles, right to the spot where her car was.

I suspect this sort of application will be available within the next few years, but someone has to create it first. Tracking elderly people is something that is also a major opportunity.
