Storyboard Gumdrop Garden: innovativeness and potential

Client 1:

This game looks quite challenging. I think the combination of the physical challenge of balancing on small pedestals and figuring out the path will be very fun. The amount of "figuring out" that the group must do seems excessive though. Perhaps removing the yellow gumdrops and the lever pull would simplify the experience? It may be simplest if some or all of the drops are only up for a fixed time, forcing you to move through the room.

Client 2:

Cute idea! I like the "keep off the grass" sign as a hint to the players.

Have you considered what will happen if a player is on a blue gumdrop as it drops back into the ground? Seems like there's potential for injury there.

I am also slightly concerned about cost in this one...that's a lot of gumdrop mechanisms to control!

Overall, I really like the concept. It fits with your theme well. I wonder if you could bring down the complexity a little bit and retain the same hopscotch/whack-a-mole feeling. What if you made the gumdrops stationary, with the ability to light up in different colors. Instead of having players step on the gumdrops,you could build thin, raised platforms through the space (call them "fences" or "garden paths", maybe) and have players walk/run along them to try and hit the ones that are lit in a certain color. I could see that being a lot of fun as players try to balance on rails while stretching over the garden to hit a glowing gumdrop.

Reviewer 3:

Nice storyboard! It seems like a fun adventure. There is a lot of potential to make this fun and engaging for all players of the team. The storyboard doesn't mention exactly how the team loses if the players step on a yellow gumdrop or the grass. Do the lights go off somewhere or something else happens? This also can be easily resettable with different combinations of colored gumdrops. Good use of childhood games and bringing it into adult-focused challenges.

Reviewer 4:

Looks entertaining. I like that there are different gumdrops that represent different challenges. Perhaps it could be interesting to be able to change the gumdrop color between runs, so that a user/team sees a different pattern each time.

Reviewer 5:

I think Gumdrop Garden is very innovative and has the potential to keep the entire group engaged and working together to both physically and mentally solve the puzzle. The different colors being different codes is an interesting mental puzzle, and then once that part is solved the speed and frequency of the gumdrops can be altered to change how easy or hard the physical challenge is. In addition the gumdrops and their variety of colors fit well with the candy theme. Finally the mechanism of all the gumdrops popping up blue at the end will allow the entire group to be part of the success of the game, and is a nice way to end.

Potential, feasibility, user experience and human factors shown in the concept sketch, Gumdrop mechanism 1

Client 1:

This seems very, very difficult. Any spring powerful enough to allow a human to jump on it without compressing entirely is going to require an enormous amount of force to compress. An electromagnet strong enough to pull this down will require correspondingly massive currents; too large to be practical on this scale.

Without a mechanism to retract the retaining pins, they will shear if enough force is applied upwards.

A solenoid usually consists of a coil combined with an moving armature that runs through it and is moved by the induced magnetic field. This solenoid seems to lack that feature.

A spring this strong could be very dangerous to stand on when compressed. It would likely throw an average person into the air if released.

Client 2:

I'm no mechanical engineer, so I'm afraid that I can't make any sort of useful comments on your three mechanism ideas. My layman's opinion on all of them is that I would consider what happens when the mechanism releases from the top position and falls back down while someone is standing on it. If the drop is sudden, one to two inches is fine - more than about 4 and I think you're in torn-ACL territory.

Reviewer 3:

Seems like a good concept. As this is the main mechanism of the whole storyboard, it does have to work robustly. As I have minimal experience with electrical engineering, I'm not quite sure if this concept is feasible or not, but you gave detailed explanations for the concept to persuade me otherwise. For all of the gumdrop concepts, would these gumdrops be able to support the weight of a whole person? What if 2 people are on the same gumdrop?

Reviewer 4:

Interesting potential mechanism. Curious about the power requirements to compress a solenoid that could support the weight of a jumping payer in an unpowered state. Perhaps a secondary locking mechanism could reduce this burden.

Reviewer 5:

I think this mechanism of gumdrop actuation is well explained and drawn out. Getting and powering a solenoid that can withstand people jumping on it seems like a tall order. Also, having pins that could be pushed in by the solenoid, will again require a very powerful solenoid. With this design it might be interesting to consider what would happen if someone jumped on a non-popped up gumdrop, as consideration would have to be taken to make sure the pins did not break, and none of the components were damaged. With this design, it might also be interesting to consider how the sensors and electronics within the gumdrop would receive power and if the cables will interfere with the actuation mechanism.

Potential, feasibility, user experience and human factors shown in the concept sketch, Gumdrop mechanism 2

Client 1:

The gap between the electromagnet coils and the permanent magnets may prove too large to pull the gumdrop up unassisted. The attraction force between magnets drops off quickly with distance.

The magnets will have to be quite strong to reliably hold a jumping person.

Client 2:

Reviewer 3:

Like the first concept, I don't have much understanding with electrical engineering, so I am also a little concerned about the feasibility of the mechanism to get it to work. Would you need a high current to raise a gumdrop that's sized for a human to stand on? Again, the same concern about the support of a human and possibility of multiple humans applies here too.

Reviewer 4:

Good self-resetting potential. When powered, will the force "popping" the gumdrop up be pretty significant? Might be useful to dampen this to reduce the slamming/impact.

return to top of page


Reviewer 5:

This mechanism for gumdrop actuation is also well explained and drawn out. A primary next step for this design might be to spec the solenoid and magnet sizes needed for the gumdrop to stay actuated up when it is jumped on. The simplicity of this design seems like it might allow for easier connection of the gumdrop electrical internals to power, however the solenoids pictured are also much smaller and thus may need more careful examination to determine if they are suitable to hold the weight of a human. Overall, the idea is intriguing and if it can be shown to work has a high potential for a great user experience.

Potential, feasibility, user experience and human factors shown in the concept sketch, Gumdrop mechanism 3

Client 1:

This concept will require much lower power levels than the previous two, and can be made to easily support the weight of a person.

Machining the bore of the gumdrop cylinder smooth enough to seal may prove costly on this scale, and an off-the-shelf pneumatic or hydraulic cylinder inside the larger gumdrop will probably be much more cost effective. They allow for driving up and down without vacuum, and integrate easily with speed control valves as well.

As drawn the topmost o-ring would leak while the piston was moving up, and only seal when fully seated at the top. It needs a retaining ring above it.

Reviewer 3:

This one seems the most complicated to me. It seems to have great potential, but the feasibility seems out of the scope of this class. I would be concerned with how to supply the fluid and if anything goes wrong, how to clean up the fluid and replace it.

return to top of page


Reviewer 4:

Favorite of the 3. Good stability in the popped and unpopped positions. One challenge may be flow rates needed to quickly pop the gumdrops, but that could be resolved.

return to top of page


Reviewer 5:

This gumdrop mechanism is well described and explained. It seems the most feasible as air or some other fluid could resist the impact of a jump rather than electromagnets. One possible consideration with this design might be fill speed - how long does it take for the piston to raise or lower the gumdrop? Might this confuse players, and if so how can this confusion be mitigated? Another consideration might be if two people could manage to step on it at once would it still be able to manage those loads? Overall this design is well explained, documented and seems the most feasible. Allowing the gumdrops to feel a little bouncy might further amuse guests and increase the quality of the user experience.

Sketching technique, clarity of storyboard and concept sketches, and their web presentation

Client 1:

The ideas as presented were easy to visually understand. Good job communicating these concepts.

return to top of page


Client 2:

Very nicely presented. The rooms you drew are much larger than the ones you will have to work with for Open World (100-200 sq. feet), but I think that this game can be simplified/shrunk to fit that.

Even though I don't know much about the three mechanisms you proposed, your sketches of them had great production value! Nice attention to detail, good labeling, and clearly described.

Your website layout is very accessible, which I appreciated. The links along the top were a good choice.

Reviewer 3:

The storyboard sketches were nicely drawn and clearly demonstrated the adventure. I would have preferred the concept sketches to be a bit larger to see in detail the mechanisms at work.

Reviewer 4:

Web presentation is great. Concepts are clearly communicated, though it would be excellent to see perspective views of the concepts.

Reviewer 5:

The website is nicely laid out and easy to use. The themeing in terms of the font, colors, background image and other images matches well with the group's overall theme. The use of buttons both at the top and bottom of the page makes page navigation easy and clear. The images are clearly drawn with perspective so the reader can understand how they would work in a 3d world. Dashed lines are used well to show device internals. The story board itself uses lots of colors and shows decorations on the walls to relate back to the candy theme. If desired for future versions, shading could be used to make the concept sketches look more 3d, but it does not seem needed at this point for understanding of the viewer.
