IoT Video Sketch Mockup
As part of my User Centered Design certificate coursework, I created a video sketch showing scenarios for a smart food container. I implemented a prop container used in the video with a small programmable microcontroller. I was responsible for all parts of this project.
The issue of food waste interested me personally and I researched demographics that would be most sensitive to the problem. I considered older people who may be on a fixed budget and learned about age-related memory degradation.
This was a target audience who could benefit from the introduction of an IOT device if the interface was streamlined.
The physical manifestation of the device did not concern me as much as the interactions with it, so I began sketching storyboards.

I created a script and slide show to present to my classmates. By reading the script while advancing the slides, I estimate the length of the video.
Feedback from the group critique:
I removed a scenario involving an intelligent fruit bowl and replaced it with a scenario about food spoilage. I also added more description of the reasons why seniors may face challenges with food waste.
After adjusting my design, I created a animatic video with the audio of my script. The visuals relied heavily on the existing storyboard assets so that I could focus on the wording and sequencing of the video.
This rough draft can be found here (2m 6s).
Filming was done at a friends house using my iPhone’s video recording capability. Audio was recorded separately (non-sync audio) to simplify editing. I made sure to capture B-roll to use while the narration introduced the persona and explained the design’s context.

I decided the most natural way to “select” a container in the system was to hold it as if showing it to the voice assistant. This interaction mimicked the traditional query between two people in the kitchen.
Person A (holding a food container) What’s in this box?
Person B I think that’s left overs from last night.
The reverse operation of informing the system of a container’s contents is the interaction in reverse.
Person A (holding a food container) I’m putting the left overs in this Tupperware.
Person B Ok!

I found the video sketch to be an effective way to convey a design in context. A video sketch would be a poor fit for communicating the design of a website, but worked very well for an IOT design.
From ideation to completion of the final edited video took the equivalent of a full week’s of work. I think this could be shorted to about three days, opening the possibility of producing two video sketches a week. A longer project could also build a collection of suitable stock footage to repurpose in later iterations.
