User Centered Design project

1. Sat-Nav
Solution

2. THE TASK
• We were tasked to come up with a new product to solve a
problem in which users will or have faced
• The problem and the solution could be of our own
choosing but would require investigation
• The solution would be one product and must be designed
from the point of view from the user and cater to the
users wants and needs
• We must produce and/or portray a prototype product as
well as the idea of the finished product

5. PROBLEM IDENTIFICATION
Next we used the research we had gathered to identify the problem
we wanted to pursue:
• We decided that we wanted to solve the problem of users; in
particular drivers of cars and vans; looking away from the road
in order the receive guidance from their satellite navigation
systems
• We found from research that there is a considerable percentage
of road traffic accidents contributable to the use of ‘sat-navs’
and mobile phones for GPS assistance whilst driving
• Therefore we decided that their was a definite justification for a
product to be created to resolve this problem

6. PROBLEM RESEARCH
Once we had identified our problem we did more research related
to it
• Researching into various products which relate to the problem
• Researching into the different types of users of various
products
• Researching into the success of various ‘other’ solutions
• Compiling all of the research into mood boards
• Below is an example of said mood boards:

8. PRODUCT CONCEPTS & DESIGN DECISIONS
The next stage was to begin to conceptualise the product in which
we wanted to create
• Did we want the product to be similar to other products already
on the market place?
• Did we want our product to be completely unique and re-invent
the wheel?
• Would our product take advantage of future technologies no
necessarily available for commercial use at this time?
• How would our project be created?

9. MIND MAP

11. PRODUCT CONCEPTS & DESIGN DECISIONS
CONTINUED….
• Our initial idea was to create a steering wheel mount for a
mobile phone which would allow the user to reduce the time
their eyes spent away from the road
• We wanted to attach the mount to the centre of the steering
wheel
• Problems with this included things such as:
• Legal and safety issues involving placing objects over the airbag
• Issues causing the phone to spin with the wheel meaning any
readout would be impossible to view and use
• Issues causing an obstruction of the drivers hands from effectively
turning the wheel

12. PRODUCT CONCEPTS & DESIGN DECISIONS
CONTINUED….
• This meant that our solution would need to be redesigned
• The redesign and rethink would involve more research into
emerging technologies and in car safety
• Our new solution was to create an attachment for phones and
sat-navs which would create a ‘Heads-Up-Display’
• The attachment would be mostly transparent and placed in the
drivers eye line on top of the car dashboard.
• This meant that the drivers eyes would not be taken away from
the road, but they could still receive the vital information that
they needed

13. PRODUCT CONCEPTS: SKETCHES

14. PRODUCT CONCEPTS: SKETCHES
Pro
 Screen can be hidden when not in use with
different suggested methods
 Simple user interface
 Design simplicity
 Simple manufacture
Con
 low stability (may fall over while in car)
 no way of connecting the phone to the
device
 Basic design may not intrigue consumers

15. PRODUCT DESIGN CONCEPTS: STORYBOARD

16. PRODUCT CONCEPTS: PROTOTYPES
Here is an example of a prototype model of the product:

17. PRODUCT CONCEPTS: SKETCHES
Here are some designs of the proposed products:

18. PRODUCT CONCEPTS: SKETCHES
Pro
 Good stability do to sticky pads
 Good incorporation of phone (text
message)
 High compatibility
 Hidden screen when not in use
 Traffic updates
Con
 Not eye catching
 Cluncky/Box design
 Screen to base connection looks weak and
may snap
 Different dashboard heights may prevent
being invisible to driver as stated on desig

19. PRODUCT CONCEPTS: PROTOTYPES

20. PRODUCT CONCEPTS: STORYBOARD
Here the satnav is located behind
the steering wheel. The satnav is
working but it doesn’t have anything
to show the driver therefore the
display is in the closed position.
Here the satnav is open, giving the
driver clear instructions without
hindering his view of the road. The
satnav will stay open until the
vehicle has completed the
maneuver.
Here the satnav is closed. Once the
maneuver is complete and there
isn’t any more information to give it
will close back down so it is out of
site and not distracting the driver.

23. PRODUCT CONCEPTS: SKETCHES
Pro
 Display screen for extra information
 Suckers to stick to dashboard
 Simple interface
 LED making it more energy efficient
 USB making most phones compatible
 Interesting Design
Con
 Complex
 Moving part may be jammed
 Power source?
 Dashboards are often curved so the
straightness of this product may
prevent it from attaching perfectly.

24. PRODUCT CONCEPTS: PROTOTYPES

26. THE PRODUCT AND POWER
• This product will need a power source in order to
function and would be best if it has both battery power
and power through the cigarette lighter.
• The battery should also be rechargeable to make it more
functional for this product.
• The cigarette lighter supplies a 12v dc power supply so
the product must be made compatible.
Portable Power banks
These are used to give a mobile phone an
extended battery life. They use a Lithium Ion
battery to store the energy for the phone to
then use as extra battery life. The lithium ion
battery is also able to be recharged so can be
used over and over again without the need to
purchase a new one.

27. LITHIUM ION BATTERIES
These batteries are very popular and find use in laptops, mobile phones, iPods and other devices. The
batteries have become so common because they are some of the most energetic rechargeable
batteries that are currently available.
Advantages over other batteries
 Much lighter then other batteries
 Hold there charge well
 Have no memory effect so do not need to be fully discharged before recharge
 Can handle hundreds of discharge and recharge cycles
Disadvantages
 Start degrading as soon as they have left the factory
 Degrade faster under higher temperatures
 If completely discharged the battery is ruined
 Requires an on-board computer to manage the battery
 If the battery fails there is a slim chance that it will burst into flames

30. FINAL DESIGN SKETCH

31. JUSTIFICATION OF THE FINAL PRODUCT
CONCEPT
We decided that we would go with Sam’s idea, a heads up display that is an
oscillating LED strip. We went with this for a number of reasons:
• The oscillating LED strip gives the impression of a floating screen, this
means that there isn’t a screen that could obstruct or distort the drivers view.
• The device tapers down at the end, meaning that it looks like a piece of the
car. Because car dashboards are curved our device will have a curved base,
this will follow the lines of the dashboard, making it look like its part of the
dash.
• The small display will give the driver the destination, and other information
they will need when setting up the device.
• There will be two ports. One will be used as a reserve power source incase
the lithium ion battery runs out, this will also be able to charge the battery.
The other will be a USB port that will be used to connect phones and other
devices to the satnav.
• The device will be attached to the dashboard with suction feet, this will stop it
moving when turning, or jumping off the dash when the car goes over a
speed bump.
• There will only be a power button on the device, everything else will be
controlled by the phone.

39. Ports
The minimalist style continues onto the back with
only 2 external ports so you can simply plug in and
go with the usb of the ultra fast usb 3 port to
connect with any phone charger and a power
cable to be plugged into the car.
This revolutionary new Sat-Nav display is in the forefront for road safety.
The placement of this display, just behind the wheel, allows the diver to
keep their eyes on the road and not obstruct their view. This slim stylish
device looks at one with your car and the simple minimalistic button
makes it easy to use for anyone.
Display
The oscillation of the LED stick means there is no
screen that will obscure the windshield screen. The
directions appear as if in mid-air as the LED lights
corresponds with the oscillation to show simple and
clear directions to follow. A second display screen is on
the device to show the destination.
Size and weight
Front width – 15cm
Back width – 10cm
Front height – 3cm
Back height – 1cm
Depth – 15cm
Weight – 0.5kg
Body
The unique curved shape of this device lets it
sit perfectly on top of your dash board and
with its tapered end it makes the Sat-Nav
looks like part of the car. The device sits on
the dash by the use of its rubber feet so that
it stays in place even with a sharp turn of the
wheel.
