Eneco 3 – Finalising the prototype

During the
last few days we are busy finishing the prototype for the presentations coming Friday.
The last things are added to our ‘house’ and the electronics are fixed into it
as well.

 

For now the
only things left to do are placing a few outlets into our ‘house’  and connecting the electronics on the back. And
then… it will hopefully work! See u on Friday, studio 1!

Eneco 3 – preview of poster and flyer

While busy building the prototype, we are already working on promoting our product.

That’s why we made a poster of the product, which can be placed everywhere. With the use of the flyer, everyone is going to love the Enotion!

Because we don’t want to given everything away already, we only preview the flyer. want to see more? contact us!

 

 

 

 

Eneco 3 – Where is my closet?!

To explain
how the prototype works, we need a set up in which multiple room can be
visited. Because the exhibition space is limited we turned a closet into a multiple
room setting. We do this by turning the closet with the open side to the wall.
Remove the doors. Attach them on the other side on the corners. Put different
wallpapers on the left, front and right side. And enjoy a livingroom, bedroom
and bathroom!

Eneco 3 – presenting parts of the prototype

Currently,
our team is working hard on the prototype. Last week we painted the prototype,
as you can see on the pictures. It is now shiny and white, you can even hear it
squeak if a finger is rubbed on the surface!

 

 

 At the
same time, we are working on the electronics. By now, the LED’s and buttons are
being installed and wired so they can be connected to the Arduino. Because it
are 94 LED’s and 45 button’s, this may take a while! In the meantime we
prepared a digital prototype for you, so u can have the experience of using the
Enotion! Enjoy!

Eneco 3: building the final prototype

After testing a paper prototype it was time to convert our previous working prototype into a new one.

We started with the design in illustrator. With the use of a laser cutter the main shape of the prototype has been constructed out of wood. As you can see there are already places for the buttons (square holes) and for the LED’s (small round holes). On the bottom of the shape their is place for the display and 3 more buttons (navigating and email).

 

 
 
Next step was to make buttons which can be placed on top of the device. We choose to make these from perspex. The icons are inscribed into the buttons with the use of sandblasting. On the pictures some buttons are white while others are transparant. This will change in the final shape of the prototype, now some are still covered with protection plastic on the back.

 

 

 
 
 

Our next step will be to paint the device just like our renders (they can be found in our previous posts). Then the electronics will be added. We also have to think of a solution for the transparency of the buttons, because they will show the elektronics behind it (which is not nice to see). For presenting our prototype we also plan to build a scene based on multiple rooms represented with the help of a closet. This will make the use of our device even more realistic. Because we are not there yet, we will show it to you when it’s time!

 

 

Eneco 3: user test

Now the
concept was clear, the user testing could start!

With a
paper prototype and a scenario we asked a few people to try it out. From the
test we got valuable feedback which we considered in our next step, building
the final prototype

 

 

 

 

 

Feedback:

-The
users understood that the buttons were representing devices, grouped buttons
were representing rooms and that the lights on the bottom of the devices where
showing the energy usage of the whole house compared to the neighbourhood.

– The
icon of the neighbourhood is a little confusing, it doesn’t show if it is only
a street or the whole village but this can be explained.

– A
green coloured buttons made some people think the where using ‘green’ energy. This
is something you should know by using the device once.

 

From the
users we also got a few tips to improve the eNotion:

– Make a
few buttons for outlets where no fixed device is plugged

– Make
it possible to show the history of energy usage for a device

 

With
this feedback in mind, we started working on the final prototype which will be
previewed in the next blog!

Eneco 3: new concept for user test!

Starting
fresh this week, we worked on integrating the feedback from the presentation in
the concept. In a very short meeting it quickly became clear what we wanted to
change so we would achieve our main goal: let the consumer save energy at home,
not only now but even on the long term.

 

The new concept
consists of a tablet-like device, which is still attached to your wall but also
portable around in your home to increase the usability. The device offers the
possibility to add devices of your own choose and make your own configuration
in this way.  By having a limited amount
of places, the user will be stimulated by tips on the device to change
connected devices when there is no longer the possibility to save energy. With
the tablet comes a sheet of stickers with icons, showing the most general
devices in a house holding. Some empty places are also available to stimulate people
to change their connected devices. For now, it is possible to connect up to 42
devices. This amount enables to connect most important devices without losing
yourself in the amount of information displayed.

 

The
devices will be blank when attached to your wall, it will only show information
if a user is in front of it or it when it needs attention.

 

The
results are some nice graphic, shown below. Enjoy!

The device asking for attention
 

 

 The device is portable for increase in comfortable use

 

 

 
  Suggestions for icons on the device
 
We will continue with small adaptions to the hardware of the prototype, so we will be ready for testing!

 

Eneco 3: Concept presentation and evaluation

How
do we keep the user motivated in saving energy on the long term?
We already thought of this in stimulating the user with giving tips and send
emails weekly, but how can be integrated this in the most suiting way with the
current concept? This didn’t become clear enough from the presentation.

 

The next
step will be to take this feedback into account while performing a user test
with the prototype. Because we think it is more useful to test the real ‘final’
concept before handing in the plans, we want to adapt the concept a little bit
next week. As far as we can see now, it will take minor changes in the hardware
so we might make it before the user test!

Eneco 3: preparing the final prototype and presentation

The
concept consists of an outlet, which is communicating with the central device.
At this central point, data is gathered on the amount of energy used by the
outlet. This information is displayed on the device by a display, which shows
the costs of the selected device. Also the usage is visualized by a LED
indicating a red, orange or green light. Different connected outlets and their
plugged devices will be indicates with multiple LED’s. By touching a LED, an
outlet is selected and the data is shown on the display. As a special function,
the total amount of energy used by the house holding will be compared with the
average usage of the neighbourhood, which information is also visualised by LED’s.
