The idea of blowing out the torch to turn it off is pretty cool! I've never seen anybody try that before. I wonder how we can work it into a torch and marry the two ideas.

This mechanism is really cool! I think people might react positively to the idea of trying to blow it out. It's a fun type of feedback to have.

It kind of reminds me of this:

Maybe a little bit of inspiration. Also maybe shows that doing this with a fan might involve fewer "custom" parts if it still works as well.

The concept of blowing on a flame is very creative! It is quite a challenge to make a realistic flame, so this is a great effort. Using multiple LEDs might help create a flickering effect and make the gag more responsive.

As I mentioned, blowing out a torch is a cool way to come up with a gag that might not seem too obvious at first, but is ultimately not arbitrary or too confusing. You seem to address the concerns about cleanliness in your user testing too.

One concern I have is actually translating this sketch model to the real torch. It might be difficult trying to implement the mesh, get a good flame effect, and mount the sensor in a way that makes it reliable but not obvious. I don't really think the fog effect that you implemented in the looks-like will actually be feasible due to the water and need to refill it, so it might have to be done with air and flowing fabric.

Focusing on the works-like model in this evaluation. Really cool concept! The strain gauge to determine when a force is applied to the flame. It'll be interesting to see how the works-like and looks-like are combined to achieve the desired effect. The gauge should be fairly incognito into the design.

I'm a little concerned about people touching the gauge rather than blowing on it - which you'll need to have a rugged gauge to meet the durability standard required.

I think this captures the testing and development of the concept in the storyboard really well!

Good model!

Your execution was awesome. It clearly works, and seems like you've shown it's very possible. Think maybe about a fan as an option as well.

The sketch model is well-executed. Testing the prototype with different users and getting their feedback was a great idea, and having over 80% of the users succeed in blowing out the flame is useful validation for further development. It might be helpful to try using different types of sensors, blowing from various angles, testing different thresholds.

First of all, I really like the user testing of the sketch model, it definitely helps illustrate that you were able to answer the questions you posed about the gag's feasibility. The model also fundamentally addresses the question of how to technically make the torch sensor, and whether or not the blowing actuation works well. As with before, I am concerned whether or not the actuation would work as well when further integrated with the final module (if you wanted to achieve a flowing fabric torch effect or something), so maybe investigating that would have been worthwhile to see how robust the mechanism was in different implementations

Also, nice resourcefulness on using the homemade strain gauge when the other sensor failed!

Simple to understand, and used reasonable methods to try out a few different options for implementing the idea. The works-like model doesn't have to be pretty! I like it, I like it, I like it! Just a little concerned about how you're going to deal with the durability issue, which this model doesn't really address.
