Comments on function-related aspects

Client 1:

Custom machining buttons out of aluminum may be excessive, considering that there are RGB lit pushbuttons commercially available with similar cycle count ratings.

Aluminum may be overkill. Have you considered HDPE?

Reviewer 3:

You put a lot of thought to the construction of the button and I like how long term durability was your key concern. An important aspect of buttons is feedback and making sure that users are aware when a button press actually "pressed." In your current model your form of feedback is purely visual and I think it might be interesting to implement some sort of haptic feedback. It could be a vibration when the user presses it or a click or some sort of spring to give resistance. The force sensing resistor is a good way to avoid mechanically sensing a press, but I think still having some sort of mechanical feedback would be beneficial. I'd also make sure that the acrylic is able to slide freely in the housing and not jam because of friction.

Reviewer 4:

The wall button appears to be well designed to hold up to repeated wear and clearly signal when it is in one mode or the other. It is slightly unclear from the other storyboards if there will also be buttons with Poisson's symbol or not, and if so how those buttons would interact. If all the buttons are permanently displaying a lightning symbol, it might make more sense to only light up some buttons yellow and never light up any buttons blue, because a blue thunder bolt is unclear whom it is helping. The aluminum back plate looks well designed an structural, though for a final product with meany buttons it might also be helpful to look into molding plastic for the main body of the button.

Reviewer 5:

Both the physical and the electrical implementations of the wall button are well thought through. Since the buttons will be struck repeatedly by the players, it's great that the design uses durable parts like force-sensitive resistors. The LED lights changing colors provides helpful feedback for the players.

Reviewer 6:

I think that the function of this design is very well thought out. I appreciated all of the thoughtfulness that went into robustness of wear including the sensitivity of force for the resistor. It was also great to see the consideration for the fabrication of the design- especially the plan for how it could be milled. As a non-engineer, I appreciated the product analogy to how a computer monitor is set up, it made it easier for me to comprehend. And of course, the considerations for the electrical force was great. Really well done.

Comments on form-related aspects

Client 1:

This is a pretty cool looking button, despite the cost of manufacturing. The lightning bolt may be confusing when lit blue. If it always shows a lighting bolt, it may be unclear that sometimes the button works for Poseidon.

Reviewer 2:

I really liked that you implemented force sensors into the buttons instead of having fully mechanical buttons. Aesthetically, I think a button with more thickness might have better hand grip for the players.

Reviewer 3:

The button could be more visual and aesthetically similar to theme of the Zeus vs. Poseidon. The only cue that shows any similarity is the engraved acrylic. Changing the shape of the actual button, maybe to the shape of a lightning bolt (instead of just a square) might help fit in with the theme a little better.

Reviewer 4:

The CAD rendering and exploded view make it clear and easy to see the button's components and features. Before this is entirely manufactured it might be helpful to user text and make sure hitting the opposite corner as the force sensor to make sure it still triggers, and see if the LEDs successfully illuminate the full button, or if the LEDs need to be more spread out around the button. The button also looks easy to use and the C1 corners emphasize it's practicality and make it less like to stab someones finger.

Reviewer 5:

The renderings are nicely done! The description clearly explains the components and how they are assembled. To integrate the wall buttons into the room's theme of a battle between Zeus and Poseidon, perhaps the buttons or the decoration around them can be made to resemble clouds for the lightning and waves for the trident?

Reviewer 6:

The form-related aspects were also good, although with the drawings I was having a hard sense of scale for human use. It would be nice to have measurements of the overall wall button and think about how it might relate to one or two hand sizes. The CAD rendering was nice and clear- for aesthetics I wish that the rendering/drawing had included the different colors that were brought up in the description: blue and yellow for the different Gods.
