Evidence of Work
For this project, we were assigned with the task of analyzing an individual's gait. Our group studied each member's individual walking pattern rather thoroughly. Through the study of one’s acceleration, velocity, arm movement, and frequency of steps over a given time period, we were able to compile an abundance of data in order to break down the simple act of walking based on height. We found that all group members had a consistent stride but variation in acceleration. In addition, we created a Gaant chart to demonstrate our group's progress over the duration of the project. We then adapted our report to create a presentation for the class through the medium of a slideshow.

Gait: locomotion achieved through movement of human limbs; one's manner of walking
The premise of the project was to measure the individual walking pattern of each individual, or each person's gait.
Acceleration: rate of change (or derivative with respect to time) of velocity
We installed the app Phyphox to calculate each team member's acceleration by attaching the phone to the subject's lower back and collecting the data from their six meter walk.
Absolute Acceleration: absolute accelerated velocity over accelerated time
We created an equation to predict the average absolute acceleration of an individual based on height.
Accelerometer: a device that detects acceleration and tilt
We used the accelerometer in Phyphox to calculate acceleration without taking gravity into account.
X Direction: lateral axis measuring movement from side to side
This axis shows the subject's torso's movement from side to side while walking.
Y Direction: vertical axis measuring movement up and down
This axis shows the subject's lift up and down while walking.
Z Direction: axis measuring movement forwards and backwards
This axis shows the subject's movement forwards and backwards while walking.
Velocity: the speed of something in one direction
We used the acceleration to calculate the velocity, which can be found on our Google Sheets. We calculated this by using the midpoint sum formula, which is a way of approximating an integral (the area under the acceleration vs time graph). The formula is (t2 - t1) * average (a2, a1) + a1, where t1 and t2 are two different times, and a1 and a2 are the two different accelerations at t1 and t2. We chose not to include these velocity graphs on our report because they were inconclusive.
Frequency: the rate at which something occurs or is repeated over a particular period of time or in a given sample
We measured the frequency in Hertz of the average number of steps in the six meter distance.
Period: the interval of time between successive occurrences of the same state in an oscillatory or cyclic phenomenon
We found the period in seconds of the time between each step.
Arm Movement: the difference between the initial point and final point of the arm
We calculated the average arm extension in inches between each step.

Reflection
This project was rather successful. One strength our group had was our collaboration. All team members contributed to the project and truly worked hard when conducting the study and analysis of each walking pattern. Through creativity and communication, everyone in the group worked together to produce a great project. Our hard work was another strong suit of my group, as all members completed their tasks diligently and without problem. However, we struggled with delegation of responsibilities as a direct result of this collective effort. My group finished all tasks efficiently, leaving little work to be done towards the end of the project. Time management was also a challenge towards the beginning of the assignment as we spent too much time brainstorming as opposed to actually beginning to get work done. Overall, my group excelled in productivity, making this a wonderful experience to be a part of!
