Sirena – Final Post

Below is 3 pages of our final app design. First is the Home screen, then our Beacons page (Beacons are your selected contacts to message), lastly is the emergency page that will be shown after holding the button for 3 seconds.

Poster Design:

Sirena is a fashion-forward cuff with the aim to prevent sexual assault by connecting women on college campuses with their social circles and local authorities. The idea behind Sirena is that if the wearer feels uncomfortable or unsafe, they would be able to press on the circular button on the top of the bracelet for 3 seconds and the bracelet would connect to the Sirena App on the phone and send a pre-set message saying you feel unsafe and also disclose your location.  The bracelet will vibrate once you send out the distress signal so you know that it got sent, and you would also feel a vibration in the bracelet when someone responds they are coming to help. However, since both Keegan and I don’t have much experience with coding and creating an app, the functionality isn’t fully functioning at this point. We still believe in the idea and would love for it to eventually work how we envisioned it to, but we have a ways to go before that can happen.

As a whole, I would say we are pretty pleased with what we were able to come up with in the time period that we had to work on it, but obviously would have wished to have it functioning even better.  We spent a good amount of time working on both the coding and design of the bracelet. The coding part, which Keegan worked on was very complicated and was what required most of the time and attention to so Keegan definitely spent more time on that than Emma did on the design of the bracelet as well as the poster. The design definitely didn’t meet Emma’s vision but that is mostly due to the limited resources we had with the technology needed.

Our original project goals were to be able to work together and have a fun and new learning experience working on something we both strongly believe in. When we look at it like that, I definitely think that we achieved those goals. However, we did hope for more function regarding our final project description and that was just too far out of our reach for now. We hope to continue to work on Sirena so we can eventually have it fully functional as to have the potential to not only help keep women safe, but also help the local police force have a better idea of where women feel most unsafe with our data and put up more street lights, promote SAFEwalk more, or station more officers in danger areas.

Some of the largest hurdles Keegan encountered had to do with the coding of the bracelet and connected phone application. Approaching something like creating an app without any previous experience was definitely an ambitious task, but in the end, what he was able to come up with is definitely something to be proud of. Emma had a couple of challenges with designing the bracelet itself. At first she wanted to sew it together with either leather or neoprene, but due to the hard and bulky technology, had to learn how to create a 3D model so it could be 3D printed. She originally started out making prints using TinkerCad, but moved on to sketchup and then ended up using NX for the final bracelet. After making a couple of prints using TinkerCad and sketchup, the prints were all separate and not the right size or fit so we moved on and Keegan was able to help her create the design using NX. The design after using NX was much better and Keegan was very instrumental in that process. The final design although was functional, could definitely use some adjustments. The button didn’t work seamlessly which was very frustrating. Also, for the future, Emma would like to have the technology engineered by possibly printing our own circuit boards to be much smaller so the bracelet could be more attractive and easier to manipulate for a more pleasing aesthetic and feel.

If we had more time, we would like to have been able to print another bracelet with tapered sides to improve the aesthetic and add some kind of design to the exterior of the bracelet. In terms of tech and functionality next steps would be to first get to send an email/text through the Simblee, this may not be possible and would require a different app development process to happen. Keegan worked with Ionic, an online app development site, for a couple weeks and found the content at a much higher level than his current coding knowledge, but Ionic did have far more applications than the Simblee mobile app alone. So, for long term growth and potential to bring Sirena to market the two of us would look to bring on someone with experience in app development to help improve our functionality.

Emma was able to get a much better idea of sizing this week. After 3D printing the base and one side, she realized the sizes should be a little bit smaller. The pieces actually came out really nicely and they were sanded down pretty well. Nonetheless, they are far too big and need to be re-worked yet again. Even though the big pieces are going to be used for the final, it is still nice to get an idea of the shape even if its a little too big. Emma also switched over to using NX instead sketch up because the dimensions are a lot easier to work with on NX. She plans to continue to work on sizing this week and work through the challenges faced last week.

Keegan worked on the NX files with Emma last week. The sketch up file had to be redone in NX to allow editing as well as exporting. Keegan continued to work on the app through Ionic Creator. The use of Ionic is proving to be more difficult than anticipated and has slowed down, but will be getting more focus this week and moving forward.

We’ve seen some challenges with coding and the 3-D printing of the Simblee housing. With 3-D printing we are able to rapid prototype our design and see where problems are, fix them, then print a new model quickly. By constantly adjusting our design we hope to get our best possible model as quick as possible.

Regarding the design for this past week, Emma was able to have a software training session with a student that knows SketchUp very well and she was able to create an updated design that will have 3 separate pieces as of right now. The design has a curvature to it that it didn’t have before which can help with the feel of it.

When creating the design, some challenges that arose included sizing and proportion and there are definitely some things that need to be changed but in order for those changes to be made, it needs to be printed and figured from there.

This week Emma will make sure to get it printed and from there have a better idea what the next steps are regarding the design. It is taking her much longer than expected but definitely making improvements.

 

This past week Keegan dealt a lot with coding of the app and improving functionality. We decided to switch to an online app development website called Ionic to create interface and perform tasks like sending SMS texts and emails. The site has proven to be very content heavy and Keegan has so far watched a lot of tutorials on Ionic and how it works but hasn’t been able to implement any significant advances.

A catastrophic setup backup almost happened with the Simblee when it stopped showing up in the port on Keegan’s Macbook. After some slightly panicked searching of the web he found out the SMC could be reset and the problem should be resolved. Luckily it was and we avoided having to order another Simblee and rush the project more.

This week has to see developments in the app and how we can send texts and/or emails when the button on the bracelet is held. Keegan will be focusing on improving functionality through Ionic.

This past week Emma was able to start 3D printing and get a better idea of how the design and tech could possibly all work together. The first print took about 3.5 hours and some challenges did arise. The first print didn’t actually end up working very well. The Simblee didn’t fit very well into the 3D printed case that was designed. Next steps include altering the sizing of the case and getting a better idea of whether the entire bracelet can be 3D printed or not. The idea behind them is that the simblee with the button attached at the top can slide right into the case, with the second circle piece resting right above the button. This way, when the user pushes down on the circle opening, there would be more surface area for the button to be pushed. With the next design, Emma is trying to get that hole turned into an indent similar to the iPhone home button concept.

Keegan worked on cleaning up the Arduino code for the vibration motor and beginning the user interface used through the Simblee for mobile application.  He was able to integrate both codes into the same one. This means the vibration motor will be working correctly while the user interface of the app runs. Keegan has been able to communicate back and forth between the iPhone app and the Simblee and update aspects of the app, however this was through found code (www.instructables.com) and is not the exact function we want. The next step will be implementing the idea from the found code into the function we want to see.

As a group we were able to get together and start brainstorming on ideas to use in the app and what we would like to see in a finished product. Some ideas included; having four different pages with a home page, the SOS page, a Beacons page (your chosen contacts), and a chat page. We’re currently working on the exact things we want on each page but have some ideas. The photo below is from our brainstorm.

On Thursday Emma was figuring out how she could possibly 3D print part of the bracelet so all the tech won’t show or be felt when the bracelet is worn. Thought of using the 3D printer to print a sort of square box that the simblee and battery could sit in, which would allow the button to be pressed from the exterior wearer.

 

Planning to continue to work on the 3D printing concept this week using TinkerCAD.

 

 Using a large cuff right now to have an idea of what the prototype could look like.

 

On Tuesday Keegan was able to get the Simblee up and running with code to use a vibration motor uploaded from computer to laptop. This was a step in the right direction, but the next step will be trying to upload code through Bluetooth not just through a corded connection. The Bluetooth on the Simblee was proven to work to at least his iPhone though the Simblee mobile application.

The uploaded Simblee Bluetooth code was for a temperature probe or just the internal temperature of the Simblee device. This code was fairly basic (and already completed) but it was still exciting to see the iPhone connect via Bluetooth and display a temperature value that actually responded to temperature changes.

Moving forward with code we want to work on how to program via Bluetooth and work on using time in the code. I haven’t quite figured how to work in sending a signal after a certain amount of time has passed. In my head it should be a simple if== “HIGH” for 3 s…then “do this” but the code has not worked out so simply.

So far we have worked on a couple of things.

Last week Keegan was able to figure out the code for the vibration motor using Arduino.

Emma was also able to work on the design analysis of the bracelet- figuring out sizing and how the Simblee and rest of the tech can fit into the bracelet. Mapping it out is a little difficult without having the entire product assembled but we were able to get an idea of how large the bracelet will be. We found some scrap pleather to piece together but now we are currently working with some clay to get an even better idea of the design.  

Problems we have faced is working with the pleather to get an idea of the shape of the bracelet- it is still in the very beginning stages.

We also haven’t been able to connect our Simblee yet- we plan on getting a new cord hoping that will allow it to work.

Next steps include getting the Simblee to work and working with the clay for design purposes.  Also working on getting the button to work.

Since last week we’ve landed on a name for our product. We are going with “Sirena” a translation of siren in Greek. Our inspiration for the name came from the idea that this bracelet would work like a safety alarm, or siren, alerting those closest to you when you are in danger.

Emma has ordered the Simblee microcontroller off of Sparkfun and it should be here by the end of the week so we can begin moving forward with tests on that. Both Emma and I have reached out to Bellabeat and Ringly, companies designing smart tech to retrieve some information on their power sourcing and integration of Bluetooth into such small pieces of jewelry. We have begun researching the problem of sexual assault on campus through multiple documents obtained through the UW-Madison Police department. The sheer amount of documentation to look through has been a lot but we are making progress.

As soon as the Simblee comes in we hope to begin testing the Bluetooth interface with the Arduino application. If the Simblee comes in by Thursday our plan will be to work with that as much as possible. The plan is to write out our prototype layout for the Simblee, vibration motor, surface mount LED, and battery by Thursday so we can start to lay the real thing out as soon as possible.

 

This our links to the two companies we have reached out to for information about their products. They have also served as a great inspiration for us moving forward.
