Project development ​

This week the major assignment is to communicate the final project progress.

Spiral project development ​

The spiral development technique is a great iterative project management and development methodology that combines elements of both design and prototyping in stages, or "spirals." Each spiral cycle involves four main phases:
  1. Planning: Setting goals, identifying risks, and determining resources.
  2. Risk Analysis: Identifying and addressing potential issues and challenges.
  3. Engineering and Prototyping: Developing a prototype or version of the product.
  4. Evaluation: Testing and receiving feedback to refine the next iteration.
  5. After each cycle, the product is reviewed, improved, and prepared for the next spiral, allowing for adjustments based on user feedback, risk mitigation, and evolving requirements.

Project development Gantt chart. ​

This Gantt chart provides a timeline for each project task related to developing a bio-signal detection toolkit designed to predict motion sickness. The chart spans dates from 5.22 to 6.13, outlining the schedule for key activities.

Project Tasks and Timeline Overview: ​

  1. Input Device Testing (5.22 - 5.26) Testing various biosensors (e.g., motion, PPG, SKT) to ensure accurate signal collection from physiological inputs. Highlighted in yellow.

  2. Output Device Testing (5.24 - 5.26) Verifying the functionality of the screen display to show motion sickness values accurately. Also highlighted in yellow.

  3. Electronic Design (5.25 - 5.26) Designing the connection setup for biosensors to interface with the micro-controller unit (MCU). This task ensures proper sensor integration and data flow, shown in yellow.

  4. Electronic Production (5.28) Producing the Printed Circuit Board (PCB) for sensor connections, highlighted in yellow, marking a key step in finalizing the hardware.

  5. Embedded Programming (5.28 - 5.31) Developing and testing the bio-signal detection and data processing programs, deployable on the Raspberry Pi, and involving wifi data transmission. Shown in blue.

  6. Networking (6.1 - 6.3) Setting up wifi communication between the Raspberry Pi and bio-signal detection module, allowing real-time data transfer. Highlighted in purple.

  7. Interface Programming (6.2 - 6.4) Developing a user interface to display analyzed bio-signal data, making results accessible for end users. Shown in purple.

  8. CAD Housing Design (6.3 - 6.6) Creating the housing design for the detection module using CAD, with a focus on ergonomics and durability. Highlighted in green.

  9. Computer-Aided Cutting (6.5 - 6.8) Cutting the logo sticker for device branding, enhancing visual appeal and project identity. Also highlighted in green.

  10. 3D Printing (6.6 - 6.9) Producing the physical housing for the bio-signal detection module using 3D printing, creating a secure casing for the components. Shown in green.

  11. Video Shooting & Editing (5.22 - 6.13) Documenting the project process, including demonstration videos for the final toolkit. This task spans the entire timeline, highlighted in red.

This timeline ensures all critical components—from hardware assembly to software deployment and final documentation—are addressed sequentially, facilitating smooth project development and alignment with the project’s objectives.
