Hello and welcome back to my blog! I had a really fun time during the first few weeks of the semester and I am looking forward to the rest of it. The first POGIL group activity we did caught me off guard since I did not remember what the terms abstraction, encapsulation, polymorphism, and inheritance meant. These concepts were taught in one of the earlier programming classes and I have done school projects and labs that involved these concepts in the past. But I don’t actually remember the terms or the clear cut definitions of them. Maybe part of the reason why I did not remember them is because we briefly went over those topics and we were also not forced to remember them since those classes were more about if you could write the code correctly. So that is why I decided to focus my blog around those four concepts. The in-class activity was a good refresher but I wanted to do research to fully have a firm understanding of them. Having a strong understanding of these concepts will help me later on in my computer science journey since these concepts are going to be seen over and over again in object orientated programming.

Let’s start with abstraction. Abstraction is basically hiding unnecessary details and leaving only the necessary and relevant details. Hiding unnecessary information is useful because, well, it is not needed to show that information to the user. An example in real life is your smart phone. All that’s important to the user is the screen and they do not need to know what processor or how much RAM the phone has.

Encapsulation is bundling data with the code that modifies the data and it can also prevent outside sources from accessing that data. In Java, encapsulation is used in classes where data can be declared as private and outside methods cannot access that data.

Polymorphism is the ability to take on many forms. In Java, that means you can perform one tank many ways. An example of that is calculating the area of a shape. You can use the same method area() to calculate the area of a triangle, octagon, or any other shape. There’s also overriding methods where the child class has the same method as the parent class.

Inheritance is gaining the properties of one class to another class. It’s like a parent-child relationship. In Java, a child class inherits all the methods and attributes from its parent class. The vehicle example is a really good one. Vehicle would be the parent class and car and truck would be the child classes. Both car and truck would share the same attributes from vehicle but also have their own attributes as well.

This has been a good review for me and the website really helped me understand what the four OOP concepts are. In the future I hope to apply all of these concepts into my work.

Hello, Everyone. How are you guys doing?

This past week, I read some articles or news related to CS (Computer Science). I finally picked a topic that caught my attention; engineers create 3D-printed objects that sense how users interact. My reason for why and seeing how choosing this article is because it looks cool and relatable for Gamers to use any controller made of small rubber pieces. 

Short Summary: The researchers found a way to combine sensing capabilities into 3D printable structures made of constant cells, enabling designers to prototype interactive input devices quickly. Even, Formed a new method to 3D print mechanisms that detect how force applies to an object. Or The structures are made from a single piece of material so that they can be rapidly prototypes. Also, A designer could use this method to 3D print “interactive input devices,” as a joystick or a controller.

For accomplishing the goal, the researchers blended electrodes into structures made from metamaterials (The materials split into a grid of duplicating cells). Also, They designed editing software that benefits users develop these interactive devices.

First, The researchers need embedded electrodes because a grid of cells creates the metamaterial. That benefits from the user implement strength to a metamaterial object; cells can spread or reduce with few adjustable interiors. They also take advantage by creating “conductive shear cells,” adjustable cells with two opposing walls made from the conductive wire and two walls made from the non-conductive thread. Even, The conductive walls operate as terminals.

When a user implements strength to the metamaterial mechanism, it running a joystick grip or pressing the buttons on a controller. The conductive shear cells expand or decrease. Even, The distance and overlaying area between the opposing terminals changes. While using capacitive sensing, those adjustments can be measured and used to calculate the magnitude and direction of the applied forces and rotation and acceleration.

For demonstration, the researchers built a metamaterial joystick with four conductive shear cells embedded around the base of the handle in each direction. Also, moving around the joystick handle, the distance and area between the opposing conductive walls change to sense each applied force’s direction and magnitude. By learning how joystick users use strength, a designer could test different handles from shapes and sizes for people with faulty grip strength in specific ways.

Second, The researchers created a sensitivity controller designed to adapt to a user’s hand. When the user holds one of the flexible buttons, conductive shear cells within the structure can diminish and send sense input to a digital synthesizer. Also, This method could allow a designer to instantly create and tweak differently adjustable input devices for a computer.

Lastly, MetaSense, the 3D editor the researchers improved, enables this fast prototyping for a software solution. The users can manually combine into a metamaterial device or let the software automatically place the conductive shear cells in optimal locations. The researchers attempted to make MetaSense straightforward, but there are tests for printing such intricate structures.
