24-hour Brainstorm Sprint and Video Prototyping.

What is scale? What is weight?

You take off most of your clothes, your shoes, and you put away your smartphone that never felt heavier. You finally step on a scale and move your head down to a numeric display. What do you see? Feeling great? Feeling awful? Why do you feel that way if nothing really changed and everything was the same just 2 minutes ago before you stepped on the scale?

That is the conflict we aimed to explore: how do weight and an abstract definition of weight, like a measuring unit, affect us emotionally. How can we introduce weight in a different way and what is weight if it’s not described as the numeric output of our interaction with a scale, but as something else? How much would it affect our perception and self-esteem?

Our concept

What if weight can be translated into a feeling?

In our concept, we tried to translate numbers into a feeling and open a conversation on how that approach could affect people’s behavior. With it, we wanted to achieve something that would be more as calibration, then a true/false system.

The outcome was a video scenario of a young guy living with bad eating habits, feeling exhausted and weak. Once he steps on a scale he starts to feel energized and strong. This feeling motivates him to change his way of living and build this feeling to be constant. During the transformation, he starts to feel less and less power of the scale, until he reaches the point where there was no difference between his and the scale’s power. As the outcome, the feeling becomes a product of his habit and lifestyle.

System architecture

Use case of our user-journey. As our task was to create video prototype this journey was also a nice foundation for our storyboard.

First, let’s define what is weight

In a brainstorm session, we mapped different kinds of scales and measurements — usual use cases and challenges with scales and how weight as data emotionally affects us.

Creating a storyboard

Creating a storyboard based on our persona and user-journey. The storyboard was also our polishing tool for our concept. As our character was the main role in this story, we have more space to build our prototype even more human-centered.


To go back on the fundamental reason of this sprint. What I learned is that video prototyping can be a really good way of translating your ideas and context of use from sketch to a format that is engaging and easy to communicate.
