how it would work

The system would work by combining the feed from a camera facing the road and satellite information to calculate where the user wants to go and what needs to be displayed to them to help them get there.

Delivery

There would be two ways that this system could be delivered one would use augmented reality glasses, and one would use a cars heads up display.

The Augmented Reality glasses aproce would give the advantage that at all points it would be acurate from the drivers point of vue. This would mean that it would work better as if they are to look around then it will move around at the wright point. The disadvantage of this is that the user would not be able to look away without seeing the information part. This system would also mean that the user has to have the information sent to glasses somehow.

If i was to use the head up display then the information would be right infronot of the user but would mean that they can clearly see the information. This system would also require the user to ware glasses so that the user can see the informaiton in the correct place so it would have to allighn what the user is looking at with what the computer thinks needs to be displayed.

My System

My system will not only provide that user with the information that they normally get with having a sat nav but also providing additional information by displaying it live in front of the users eyes. This will mean that they will have to spend less time looking away from the road. From the drivers point of vue they will see something like this.

The main advantage of this kind of system in this situation is that the driver can clearly see where they are supposed to be going so they don't have to work this out. The reason i have included a section in the top right that shows the information that is commonly displayed to users in the current system because many people use this information as they don't have to work out when they are going to arrive.

Sat Nav and complex roads

Sat <>Navs also have a problem that they try to give the user all the information required but on some of the more complicated roads this becomes a problem because although they are good at giving the user the information they are very limited with what information they can give.
Meaning if you are aprocing a double roundabout the sat nav would say go straight on at the first roundabout and then the second exit at the next roundabout. This is very informative but it the maximum that the system can string together with two comments, if you then needed to take the next right you have to wait till you are at the second roundabout or even off the double roundabout before you are given this information.

But in a more complicated road network there are a lot more limitations that mean that the system is not able to give the user much information. This has become apparent if you drive in Swindon becouse of the nicknamed "magic roundabout" which consits of 5 seperate roundabouts all next to each over.

There are a lot of examples like this where the sat nav knows the directions but is then limited to what it can display to you, This is the main reason for the problems with the roundabout in Swindon not that it is hard to navigate but people get confused when following a sat nav round it.

Problem with sat nav

Sat Nav is a fantastic invention it allows the user to concentrate on driving and not on navigating. This makes it safer for them to drive and safer for all road users. There is one major drawback of sat nav and that is the fact that it is confined to a small screen that the user has to check, This is braking the most important part of driving which is never take you eye off the road.

Sat nav is a tiny representation of the real world.

There are also some situations where a sat nav is not the best option over a sign and some common seance. Lorry drivers have had some bad press for following just sat navs and ending up stuck and many people believe that if you gave a driver a sat nav that directed them over a cliff they would probably follow. This is mainly because the systems are developed or designed for a individual system, if you could set what car you where in and its detentions then you would not have a problem because the system would know if you could go down a road or not.

Don't follow your sat nav

The other main isue is that if you are following a sat nav you are quite often end up in the wrong lain at a roundabout or junction and end up causing an inconvenienced to other drivers. This is often coursed by a sat nav saying go straight on at the roundabout so you go in the left lain to then discover you can only go straight or left which means your in the incorrect lain.

Proposal

My proposal is to create a augmented reality system that provides the same functions as a satellite navigation system. The user puts in there destination and the root information is displayed infront of them, also there root will be displayed on the road infront of them.

The advantage of using a system like this would be that the user would not have to look down at a screen to see where they should be going, this would increase the safty as they would not need to take there eye's off the road to confirm there root.
The second advantage of this type of system is that the user can see which lane of the road they should be in, with a standerd sat nav the user gets told that they need to take the second terning off a roundabout, which depending on the roundabout you could need to be in the middle lain or the left. This often leads to people being in the incorect lain so they are forced to change lain which can course acidents, so being pre informed on which lain to be in would mean that the driver is safer.
