ferrofluid appearance concept sketch comments

Reviewer 1:

The one point perspective works to show us what the concept is. It seems like this idea has a lot s of potential to provide a very neat user experience since ferrofluids are not common place so it will be unknown to most participants. What are the two control areas doing? How will it generate teamwork? Is there a way to involve more than just two players. Overall it looks like a lot of fun to play with.

How well will a projector work on a such a dark fluid? It is my understanding that dark/black surfaces tend to absorb light.

Reviewer 2:

Projecting images onto the ferrofluid is a really cool idea! How will the players know how to orient of the table? Will there be a grid already projected? There's a lot of buffer between the visitors and the ferrofluid display. This is good for safety, but might make it difficult for the visitors to see what's going on in the tank itself. Will there be some sort of cover over the top of the ferrofluids? Is splash a potential concern? Also, will two controllers be enough to engage a large group?

Reviewer 3:

Its an interesting concept. Ferrofluids are super sci-fi and can do interesting things. The appearance is good. I am concerned about the ferrofluid pool. It seems to contain a huge amount of the fluid. I have heard (and am not 100% sure) that the fluid tends to settle down with time and evaporates leaving behind sediments. The maintenance of the pool may be a challenge. A possible solution can be to cover the tank. That way, no dust and trash can go into it, and you can control the environment inside it.

Although ferrofluids are reflective, they are black. I am not sure if the projector will serve its purpose.

Reviewer 4:

The effect that you draw would be totally awesome! Yet, it is close to impossible to form ferromagnetic fluids like that. You need a lot of current, very big and strong magnets and a ferromagnetic fluid with a low viscosity.

If you would build it a lot smaller it might work. But I would consider to accomplish this effect in a different way. If you could find one that nevertheless looks so much like an alien machine, it would probably be the coolest game of the class.

Client 5:

I like the idea of using ferrofluid in a cooperative game a lot -- a couple stations (maybe 4?) that control the fluid to achieve a goal would be visually unique and fun.

Client 6:

I like the overall appearance of this interactive.

I would be careful with materials choices though.

You want materials that are robust but easy to keep clean!

ferrofluid interaction concept sketch comments

Reviewer 1:

The image here effectively conveys the type of control that the user will be required to input but it requires a prolonged examination to understand. Is this display in red interactive or fixed? Also, calling it an iso-elevation map might help make it clear what type of puzzle this is. Does this require thinking from the participants or do they just need to directly match the map? Will the sensitivity make this hard? Are they going to want to just play with the device rather than complete the task assigned?

Reviewer 2:

I like the decoupling of the position and height controllers to force teamwork. To engage larger groups, you could have separate controllers for each of the target points (so 6 total instead of 2), or separate control for the x and y coordinates. Be careful about the spacing of the levers; if they're too close together they will be difficult to manipulate.

I think you should have a way to lock in the position/height of each point (simple buttons?) so that if players accidentally knock levers out of place, they won't have to start over.

Reviewer 3:

I like the challenge. Splitting it into two halves is a good idea to make it a team effort. I understand that one panel controls location while the other control heights. Using the lights around the pool gives feedback to the whole team, so it is a nice way to involve everybody.

Reviewer 4:

The interaction is quite good. I like the idea to accomplish a given geometry/height that the screen indicates. I don't quite understand how 1 or 2 people could accomplish the game or more than 3 or 4 people could participate in it. It might help to explain that a bit further.

Furthermore, my concerns concerning the technical feasibility still apply.

Client 5:

This is a cool idea -- terraforming the land, perhaps.

Ferrofluids seem particularly good at going this type of thing, forming terraced landscapes, this could be a great challenge.

I love games that require the group to work together.

return to top of page


Client 6:

I like that this game has 2 sets of controls, but I suggest you add more.

The group size can get as large as 15 people!

I would make sure that any game play you have, it is very clear to the user who did what.

That means that you want to have audio feedback as well as visual feedback whenever a button is pushed, lever moved etc.

ferrofluid effects concept sketch comments

Reviewer 1:

How do we know which peak is correct from this feedback system? What happens when two of three peaks are correct?

Reviewer 2:

Using color to indicate completeness is a great idea. Be careful with colors like red, green and yellow though. They're already pretty loaded with external meanings (ex: red = stop/warning). Would the lighting of the fence block the players' views of the ferrofluid tank itself? If the players are going to be looking at the map on the controller, maybe the lights/feedback should be on the control table instead of the fence?

Reviewer 3:

The effects will look great if you are able to implement it. However, I believe implementing it will be a challenge. Given three peaks that you change the height and position, you will need three equally sized steel shapes that can move in X, Y and Z. That would require: 1. A large volume below the pool (If the steel peaks are not telescopic) 2. A large amount of ferrofluid (if there is no elastic membrane between the peaks and the fluid) 3. Three bulky mechanisms to move the steel peaks 4. Something to prevent the ferrofluid from interfering with the mechanisms.

I will recommend you scale the pool down to probably the size of a coffee table. That will be easier to implement and cheaper to maintain.

Reviewer 4:

I like the idea of LED lights that indicate a certain status or level of completion. I would consider though to not add more effects to the game than necessary. It is already a complex game that would certainly be an eyecather, it does not need more features. (At some point people might get confused concerning all the stuff that is happening).

Client 5:

Providing a clear visual reward -- simple feedback for their success -- is very important.

Being able to use lights and cool movement of the ferrofluids to do that can result in a very visually unique experience.

Client 6:

This game seems like it could be a lot of fun.

Make sure that the "maps" are clear and easy seen.

I suggest they live on a monitor so that if a group solves the game quickly, another map can appear.

Or if the game is too hard and too much time has elapsed, the map can zoom in, making the targets bigger and easier.

Overall concept sketch clarity and presentation

Reviewer 1:

The website is very clean and pleasant. I think they sketches are very nice. I particularly like the second interaction sketch the highlights on the joysticks are very effective. Unfortunately the layout is a bit confusing since the appearance, interaction and effects are separated into three separate pages. We end up needing references between the pages since they are interdependent. As a reader it is hard to understand the nuance of the design while flipping through many pages. It is advantageous to have a uniform website but this idea feels that it may not fit into the structure used.

Reviewer 2:

Nice drawings! I like the use of both warm and cool tones to differentiate between the ferrofluids and the rest of the space. Your interaction sketch helped to clarify the challenge (especially with the elevation map).

Reviewer 3:

The sketches are good and neat. I found it slightly difficult to understand the sizes at a first glance because there was no standard reference. If a person would have been there in the frame, it would have been easier.

Overall, the web presentation, the sketches and the description do their job well.

Reviewer 4:

Clear website and I like the design of it!

I would change 2 things though, your name seems to be Zhuoxuan Li and/ or Fanny. When I clicked on your link, I did not see the name of the person I need to evaluate, that was confusing. Maybe put the other name behind Fanny, but defiently indicate who you are ;)

The second thing is, that I would make the words on the button of the page with which you can navigate, a little bit bigger and maybe in a more visible color.

Client 5:

Nice drawings, and helpful annotations -- this is great.

Client 6:

This presentation was clear, but I would have really liked to see more details!
