Project Background

Our partners at Arthur Murray Dance Centers would like to give their clients the ability to track their health whilst dancing. The purpose of this project is to research, identify, and apply alternative technologies that can be used in this process to show the students the health benefits of dancing.

Requirement gathering

We collected the requirements through several phone interviews with the client. We conducted them as semi-structured interviews because, according to Chapter 7.4.2 of Interaction Design by Preece et. al., a semi-structured format can help us “combine the features of structured and unstructured interviews and get more information we interested on the basic of preplanned questions.”[1] (This was also mentioned for our HCI requirement gathering.)

The client also gave us a couple of use cases which helped us with designing personas and describing the project goals.

In our process we also introduced the client to alternative technologies that can be used and gave him a full description and evaluation of the differences.

At the end of this process, we prepared several documents where the requirements where outlined, including a MoSCoW list, Project Goals, Personas, Risks Assessment, Evaluation and more. We have done communicated these documents to our client via a presentation, which we presented on an Ad-Hoc call to get a “green light” for the project. Everything went well and our project requirements where approved.

Finally, we made sure to include on our bi-weekly call agenda, to briefly go through every requirement, describe the status and re-prioritize or add new requirements if the client needed so, as we were taking an agile development approach.

Project Goals

• Research different wearables and devices that could be used to track health metrics
• Use 3D cameras to capture body tracking and extract health metrics from this video
• Use the Apple Watch to extract health metrics when dancing

MoSCoW Requirements List

ID	Requirements	Priority	Contributors
Must have
1	Relatively accurate body and skeletal tracking of a single person dancing	Must have	Yide
2	Apple Watch integration with health metrics available after session has ended. (The health metrics from the Apple Watch include calories burned, average heart rate, duration of dance and the no. of steps taken)	Must have	Jan
3	Researched, analyzed and considered alternative technologies to track and monitor health benefits of dance	Must have	Jan,Yide,Alex
Should have
4	Ability to display video with skeletal tracking overlaid	Should have	Alex
5	Ability to save skeletal tracking video	Should have	Alex
6	Ability to save the data from one dance session in a file	Should have	Yide,Alex
7	Ability to calibrate to the user's proportions and the position of the floor relative to the camera	Should have	Yide,Alex
8	The system should be easy to use and set-up	Should have	Jan,Yide,Alex
9	Simple analysis on skeletal tracking that is health/dance related. As an example, measuring the activity level of the user, or the height of their limbs.	Should have	Yide
10	The Apple Watch data and skeletal tracking data should be viewable on a single integrated dashboard	Should have	Jan,Yide,Alex
11	All the health metrics that are gathered and displayed should be relatively accurate and repeatable	Should have	Jan,Yide
12	A user application, where all their dance sessions and health data would be visible for them (usable without the help of a technical person)	Should have	Jan
Could have
13	A simple user interface	Could have	Alex,Jan
14	Relatively accurate body and skeletal tracking and display of two people	Could have	Yide, Alex
15	Have the data be stored in a database semi-permanently	Could have	Jan,Yide,Alex
Would (won't yet) have
16	Automatic posture corrector via vibrations in the Apple Watch	Could have	N/A
17	User survey after each session to track their mental health	Would have	N/A
18	Machine Learning implementation that recognises the different styles of dance	Would have	N/A
19	Might turn into an iPhone-centric app	Would have	N/A
20	Other wearable integration (smart shoes…)	Would have	N/A
