Feedback on the concept explored by the sketch model

Client 1:

I appreciate the time that you put into this model. I do think that you could buy essentially this as an off-the-shelf product and save yourself the time though. I would have liked to see you experiment with a pre-made spring loaded lever to gauge things like the sensor positions, how fast the handle snaps back to center, etc.

Reviewer 2:

I think the concept explored is pretty clear and makes sense.

Reviewer 3:

I liked that this lever is re-settable and can be used in variable ranges. It looks like it would be a great tool for 5-wits to use in their rooms. As for the sketch model it looked OK -- it would have been cool if you were able to make the variable pull part of the model a little less tank. I also would have liked it if you had mounted the lever to a "wall" to feel what it's like to use on the wall.

Reviewer 4:

The sketch is awesome and definitely was constructed with thought and care. If the color of the light of the lever corresponds with the action that needs to be performed it would help users draw the connection. It is a little unclear from this storyboard how the lever is going to control different things though. Is there going to be a certain degree that they must turn the lever to in order to unlock the artifact? Maybe it will be a series of rotations like a locker where they need to go from blue, red, to green?

Reviewer 5:

I like the concept of holding a lever at a certain angle to allow a teammate to complete a task. It's a neat idea that encourages teamwork and is easily reset.

Feedback on the execution of the sketch model

Client 1:

There is not a whole lot of detail in your website for me to judge this by. Some design drawings of the mechanism and the circuit would have been nice.

From the couple of pictures you do have, it looks like this model is taped together. If I were actually going to use this to develop a concept further, I would be very concerned about durability. Your design depends on the handle dictating the position of the contact closure at the bottom of the vertical rod - if anything slips, the connector will be out of place and your model will be buggy.

Reviewer 2:

I think I'm not completely sure from the image what the different parts are and their functionalities, so my feedback is mostly based off of the written description (maybe add a diagram and/or labels in the images in the future?). I think the spring makes sense since it's supposed to revert back to an initial position. I'm not too sure how the metal plate and circuitry works, but maybe there is a more simple, robust way (if it's not already)?

Reviewer 3:

Execution of this sketch model was well done. I think it was able to answer the question you were asking and showing how a real lever would function. It was slightly jank so I'd would have like to seen it a little more functional, but otherwise looks good.

Reviewer 4:

The execution was great! It was a very neatly assembled, performed well in the class presentation, and was a great part of the room to spec out and test. Great work!

Reviewer 5:

The model is an effective proof-of-concept that clearly conveys what the gag will do. A small video on the website would help convey the message of how it operates with more clarity but the descriptions were also helpful.
