Iteration 3: Speculate Phase

  • Define the MVP (minimum viable product)
    • My MVP will consist of a housing unit with three load cells providing weight readings to the Arduino. The Arduino will also be connected to an LCD screen that will be able to display the plate is on, zeroed, and ready for food to be place on it. An LED strip will also be connected to the Arduino in the interior of the housing unit that will light up based on the weight readings from the Arduino. All of this will be placed in a housing unit that is aesthetically pleasing.

  • Re-prioritize feature/work item list if needed (ALL features) and updated estimated workload for each feature/work item if needed (ALL features)
    • High Priority Items
      • Construct final prototype (mount load cells, LCD screen, Arduino, LEDs, and aroma release) – (4 hours to account for the possibility of messing up and doing this twice) – 5
      • Laser cut and edit housing design for more precise LCD screen mount and aroma capsule access – (6 hours to measure new pieces, buying hardware, setting appointments, and driving around) – 5
      • Laser Cut acrylic stars for star tracker and installation, frosted paint – (3 hours to set up appts, laser cut, and install (includes transportation time) – 5
      • More plate housing designs (sketches and possible 3D models) ( 2-4 hours depending on time) – 5
      • LCD countdown feature so user knows how much time they have to serve food before it is weighed – (4 hours to code and test) – 5
      • Incorporation of one more aroma release component and the development of savory scents – (3-4 hours to drive around, soldering, code and incorporation into my prototype)
      • 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
    • Medium Level Priority – Not MVP but would be nice
      • Speaker embedded in plate or starboard, allows for sound to play when a star lights up on tracker (3 hours to code and wire) – 3.5
      • Possible integration of a button for users to press when food is placed, no need for timer then to grab initial weight reading
      • Embed LEDs in housing unit and code different color interactions based on the appeal of color in relation to food (6 hours) – 4
      • 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) – 3
    • Absolute Lowest Priority Items
      • 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 
        • 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
  • Work planned for iteration 3 including:
    • Feature list for iteration 3 (totaling 24 hours)
      • Mount all hardware into final housing prototype (4 hours to account for the possibility of messing up and doing this twice) -5
      • Laser Cut and edit final housing design to account for second aroma release component, better LCD screen fit, battery access for the LEDs and access to aroma capsules (6 hours to measure new pieces, buying hardware, setting appointments, and driving around) – 5
      • Develop more housing design ideas through sketches and possible 3D modeling ( 2-4 hours depending on time) – 5
      • LCD countdown component for the time the parent has to place food on the scale (4 hours to code and test) – 5
      • Development of one more aroma release component and testing scents (3-4 hours to drive around, soldering, code and incorporation into my prototype) – 5
      • Laser Cut and install acrylic stars for LED component (3 hours to set up appts, laser cut, and install (includes transportation time) – 5
