Aplications and Implications
According to Wikepidia, in engineerin, system integration is defined as "the process of bringing together the component sub-systems into one system and ensuring that the subsystems function together as a system".
Some importan aspects are:
Requirements Analysis: Identify the specific needs and requirements for the integration.
System Design: Design the interfaces and interactions between subsystems.
Testing: Test individual components to ensure they work correctly in isolation. Test the interactions between integrated subsystems.
Maintenance: Apply updates and improvements as needed.
On this week's assignment we have to define the scope of our final project by answering some questions.
Questions
What will it do?
By using conductive threas will detect the positions of your finger and using that information will know what kind of gestures the user is doing. With this gestures the user can make certain actions like change the song, turn up or down the volume, accept calls, etc.
Who has done what beforehand?
Google's Advanced Technology and Projects group (ATAP) created a project called "Jacquard". The idea of the project seeks to create smart garments capable of performing the same actions as a smart watch but unfortunately, Google shut down the project for unkown reasons. The only launches a jacket in collaboration with Levis.
Masison Maxey, the CEO and founder of Loomia, devoled a proof of concept for a foldable, drapable, large surface area capacitive touch textile using an
Adafruit Flora microcontroller. The idea is a large user interface that can be folded and carried for creative work. This Textile trackpad can be used
to replace a computer mouse and could also be used to model, sketch and draw in the computer.
What will you design?
The thing I am going to design are the PCB using a XIAO ESP32C3 as a microcontroller since a need a bluetooth and this one already includes it making the PCB smaller. Also I will design the PCB case and the thing that will connect the small divice into thee trackpad.
What materials and components will be used? Where will they come from? & How much will they cost?

What parts and systems will be made?
First of all I have to create on KiCad the design of the PCB, this one has to be small as posible. Once the PCB is made, I will used SolidWorks in order to create the case and save it as .stl file. On Cura I will generate the .gcode file so I can 3D printed.
I will also have to create an app on APP Inventor to make the divice customizable.
Finally I am going to cut in laser a piece of clothe to make the trackpad an put it on the sleeve. And to connect this trakpad with the divice I will also have to desing and 3D print some pieces that will hold the female pin headers.
What processes will be used?
PCB Fabrication
Soldering the PCB
Programming the microcontroller in C++
Desgin the 3D printed pieces
Laser cut the piece of clothe
What questions need to be answered?
How am I going to make the trackpad?
How am I going to design the app in order to be as intuitive as posible?
Who is the target audience of this sleeve?
How comfortable will it be to wear it?
How will it be avaluated?
The aspects I think we need to evaluate in order to see if the project is a success are the following:
The divice will detect the position and gestures of the finger.
The divice wil work perfectly with the app.
The divice will be very customizable.
