While the emoji slider is beautiful and fun, I wonder how it affects the validity and rigor of the survey responses - By applying negative connotations to negative responses, this might influence the responses that users will give, resulting in a skewed perspective on the demographic.
This was my first thought too, it seems more about making the form fun and friendly than collecting impartial data if you could skew users thoughts with a really nice friendly emoji or make them feel bad for submitting bad feedback with one that's sad.
Be interested to see if that's just a theory or if this could somehow be tested/
While I was really hoping this article would be about improving boring long forms like you'd see in financial applications or the like, that have hundreds of fields... I must say the emoji slider is very awesome!
In some situations (like evaluating features) you might consider a Max Diff analysis over the Likert scale.
A thumbs up emoji to using an emoji slider to express level of satisfaction/agreement without having to use words.
I think we're going to see a lot of changes to forms. I can't wait to see how AR and VR approach it.
