Iteration 1: Speculate Phase

In this post, you will find…

  • Prioritized Total Feature List
  • Estimated Workload for all features
  • Work planned for feature list for iteration 1 (Should equate to about 24 hours of work)

My prioritized feature list will include all possible features for my Interactive Eating Plate. The features will be prioritized on a scale from 1-5, with 1 being non-essential and 5 being most essential. It is very possible that over time and after user feedback, that a feature ranked 1 can become more important, or a feature ranked 4 can become less important. To start, I made a tree map for the possible use cases of my product. Then after creating this tree map, I identified the possible features for the product based on the use case.

Prioritized Feature List (with estimated work time)

  • 3 Load Cells connected to HX711 Load Cell Amplifier, connected to Arduino, providing 3 weight readings (6 hours to wire circuit and write code) – 5
  • Design and 3D print the pieces that will connect to Load Cells to increase surface area to hold items allowing for a weight reading (12 hours to design and 3D print time) – 5
  • Design and model Star Tracker board (4 hours) – 4
  • Laser cut, and construct Star Tracker board (4 hours) – 4
  • Model all components to get a better idea for housing design (8 hours of rhino) -5
  • LEDs wired to Arduino that light up and react to Load Cell Readings for plate interactions (6 hours to wire and write code) – 5
  • LEDs wired to Arduino that are inside the Star Tracker board that react to Load Cell readings (4 hours to write code and wire) – 4
  • LCD Screen and switch connected to Arduino that shows current weight and ability to zero plate before food placement ( 4 hours to code and wire) – 2.5
  • Speaker embedded in plate or starboard, allows for sound to play when a star lights up on tracker (3 hours to code and wire) – 2
  • Design of Load Cell Housing in Rhino and prototyping (3D prints/cardboard prototype) (12 hours) – 5
  • Plate prototyping (silicone model, 3D prints, casting?, portion demonstration in design) (6 hours) – 5
  • Embed LEDs in housing unit and code different color interactions based on the appeal of color in relation to food (6 hours) – 3.5
  • Aroma/Chemical release to combat unpleasant smells that make food unappealing or cause nausea (6 hours) – 1
  • Use of audio speaker to play encouraging messages from family or general prerecording ( 8 hours) – 1
  • Meal Progress Bar on LCD screen that lives on front of housing unit (modeling to fit in housing and programming the screen to get weight readings and reflect it in progress bar) (6 hours) – 2
  • Haptic Feedback utensils for eating plate (60 hours) – 1
    • Design of Utensils
    • Incorporation of of electronics in utensils to create haptic feedback
    • Bluetooth to connect utensils to plate to set an eating pace based on food consumption
  • Incorporation of a fan to pull aromas away from user (on/off switch) (6 hours for circuit and code) – 2
  • LED interactions that help set a manageable eating pace for user (programming 8 hours) – 4
  • Features that are ranked 1 and outside the scope of this project but could be part on an integrated system with the Interactive Eating Plate
    • Haptic Feedback Utensils
      • Materials suited to users preferences (sensitivity to metallic utensils, use of matte ones)
      • Haptic feedback to set an eating pace based on total desired eating time and food left on plate
    • App
      • Nutritional Information to be stored and kept based on what is on plate (photo recognition or manual input in app)
      • Saves profiles for nutritional goals
      • Save profiles that allow device, app, or internet access based on positive eating habits
      • Recommended grocery lists based on what foods were ate the most or fastest
    • Wifi Connectivity of Plate
      • Meal completion can unlock wifi on certain devices, or apps, or provide overall screen time on a certain device
      • Devices connect with wifi to allow for nutritional tracking and possible parental controls for kids as motivational factor 

Work Planned for Iteration 1 (approx 24 hours of work)

  • 3 Load Cells connected to HX711 Load Cell Amplifier, connected to Arduino, providing 3 weight readings (6 hours to wire circuit and write code)
  • LEDs wired to Arduino that light up and react to Load Cell Readings for plate interactions (6 hours to wire and write code)
  • Design and model Star Tracker board (4 hours)
  • Model all components to get a better idea for housing design (8 hours of rhino)
