<p>Sasha, A sash that collects badges, in which each badge contains memories such as who the badge was issued to, when the
badge was completed, and a special message from the girl scout's team lead. The sash is also a talking travelling companion,
providing encouragement, excitement and entertainment for the scout's adventures ahead. This sash is meant for young
girl scouts who wish they have a magical item that can interact with them and keep them company on adventures. The idea
is inspired by Dora the Explorer, gamification, and of course, Girl Scouts.

<h3>Project Summary</h3>
</div>
<div>
<p>This sash is interactive, it promotes conversation between the itself and the user.
Every time you hold up a badge for the sash to review, it has different opinions in the badge and outwardly says it.
When you squeeze the sash, it will say different things depending on how you squeeze it.
<br/>
<br/> This sash can be considered an accessory, because it is not necessary for the user but can be used to enhance the user's
experience. I wanted an accessory that promotes achievement and adventure, but also can be a travelling companion on
those long and lonely adventures. I chose Girl Scouts to be our target user since the sash is a part of their uniform,
so it would be easier to make them wear the sash instead of a general user, and their goals match what I wanted to portray
in the accessory.
</p>
</div>
<div>
<p>
I tried to come up with different circumstances that involved problems to solve, and how wearables can help address
them. Many of my initial ideas involved general utility and was not directed towards a specific user. These were utility
and medically oriented, and although that's not necessarily a bad thing, we as students don't have the resources to
get the knowledge, experience or user set for this project.

</div>
</div>
</div>
<p>
I chose the sash to refine because it seemed interesting and had a characteristic beyond general utility, with some meaning
behind the accessory. I didn't want just a cool accessory that does things, I wanted to have a purpose behind it.
Considering myself to be a very task/goal oriented person, I chose the sash idea because it fit well with my ideals.

<h3>Refinement Sketches</h3>
</div>
<p>In these sketches I tried to define the context of the sash so it will be directed towards more specific users. Will it
be for gamers? Could it be used in a beauty pageant? One problem I ran into is the fact that, unless forced into it,
nobody would realistically wear a sash in their normal day to day life. It was here in the refinement sketches that I
decided to design a sash for girl scouts, since it is a part of their uniform anyways and it would be easier to use it.
I was also a Girl Scout once back in the Philippines (a long time ago), and I thought it would be cool give the sash
a makeover, and redefine what it does and what it looks like :)

<h3>Design</h3>
</div>
<p>
Along the way, (mod #12 in the sketches above) I also drew inspiration from Dora the Explorer, where Dora has the talking
map and backpack. I was reflecting back to the time when I was young and watched this show constantly, and I thought
to myself that it would be cool if an inanimate object talked to you, and kept you company on adventures. This is partially
why Sasha says Spanish words like "Caliente" as well. Not only will the sash keep you company, but it would have a personality
and feelings associated with it. Sasha will occasionally cry out when you squeeze her too hard, but will also ask if
you are OK since she knows that you are probably stressed out if you are pressing that hard. When you give her a light
squeeze, I envisioned that it is synonymous to a loved one lightly squeezing your arm in greeting. In this respect Sasha
will respond with a greeting as well. When you're feeling pumped up, you can give her a slightly harder squeeze and she
will PUMP YOU UP with encouraging phrases like "Let's go!" or "One step at a time!".
<br/>
<br/> Sasha will also let you know what she thinks about your badges. If you hold up a badge to her, she will encourage you
to go further with your goals if the goal is in progress. If you have finished a goal, she will say positive things like
"good job!", or "you're fantastic". If the badge is old, occasionally she will say comment on how old it is and ask what
you're up to now. Additionally, when you hold up the badge to the scanner you can see the progress bar, and the
Team Lead's special message to you upon completion of the badge.

<br/>I printed some Girl Scout badges in color and cut around them, then I cut velcro strips to match the size of the
RFID tag. One challenge that I came across is that sticking the velcro's sticky side onto the clear RFID tags will
actually destroy the coating of the tag. Instead, I hot glued the tape onto some paper, then stuck the tape onto
the tag itself. The other side of the tag is taped on the badge paper itself.</p>

<div class="col-xs-6 col-sm-8 col-md-3 col-lg-3">
<p>
<br/>To implement the squeezing aspect, I chose a force sensitive resistor (FSR) hooked up to an Arduino. From what I've
heard, using an FSR on an Arduino is significantly simpler compared to the Raspberry Pi. To simulate actually squeezing
the sash, I encapsulated the FSR in foam , tied two rubber bands to it, and hot glued some parts of the foam to
make it the FSR stay in place. </p>

<div class="col-xs-12 col-sm-6 col-md-12 col-lg-12">
<p>
<br/>I made a little pocket for the RFID reader to hide in, and a little gap at the bottom for the cord to connect
to (from the laptop to the RFID reader)</p>
</div>
</div>
</div>
<p> As for the software aspect, this project was made using the Arduino, Windows Presentation Foundation (Phidget RFID Scanners), and I used NetworkIt (source for under Sources) to have these devices communicate back and forth between each other.
Some things I have changed from my refinement sketches include additional phrases to allow for some diversity into what Sasha says, and incorporate more of a funny personality. Every so often, she sings!
</p>
<div style="padding-bottom:10px">
<p>You can obtain visual cues from Sasha as well:</p>
<ul class="custom-list-u">
<li>Light squeeze = LED stays the same</li>
<li>Medium squeeze = LED turns yellow</li>
<li>Hard squeeze = LED blinks RED twice.</li>
</ul>
</div>
<div style="padding-bottom:10px">
<p>When holding a badge to the RFID scanner:</p>
<ul class="custom-list-u">
<li>progress is below 50% = low green LED light</li>
<li>progress is above 50% = high green LED light</li>
</ul>
</div>
<p> I also designed the sash in such a way that it actually kind of resembles a physical achievement sash. For the voice of the sash I used my brother's voice
and changed it to a higher pitch to make it sound more cartoonish.</p>
<p>Other things that did not work so well is attaching the speaker to the sash itself. Since I was already using the Force Sensitive Resistor to the Arduino, I could not attach the speakers to it since I needed to have some kind of memory storage in the Arduino. The only other alternative was the Raspberry Pi, but using both the Arduino and Raspberry Pi, along with the Phidget RFID sensor, seems like too much of a hassle for the time allotted to us. In the end I chose the laptop to play the sounds for me.

<h3>Final Thoughts</h3>
</div>
<p>Upon receiving feedback for this project, I realized I had to be more specific on what type of Girl Scout will use the
sash (experienced vs inexperienced) , and that the interaction space needs to be richer. Maybe for future iterations
I could have the sash be used for younger Girl Scouts who are inexperienced, and make the sash help the scout in different
situations. This project was challenging for me, not only because it was directed towards hardware which I have no experience
of, but because it was not directed towards a specific client, which made it hard to target a specific user. I learned
to think of different users first and try to design for them, rather than thinking of different generic problems and
try to solve them using wearables. I also in this project that I learned the value of sketching; continuously iterating
through your ideas until you have a solid plan of what you want to do.</p>
