I’m not sure that I would label it as a game, more as interactive data. I think that the link to a specific action is great – although the action itself may need to be something more convincingly effective in addressing air pollution.

I liked how you tailored your goals to the medium and the audience, focusing on making the video filter simple and engaging. This campaign makes the topic of air pollution more approachable and shareable.
The connection to COVID-19 and the reduced air pollution from shelter-in-place restrictions does make this video filter more relevant to the current time period. I wonder if this might lull users into a false sense of security and thinking that everything is fine now that we’ve reduced pollution a bit,even though pollution will likely get worse again once restrictions are lifted. And since the future is modeled based on taking action today, it feels like the users just have to go along with the default option to get that better future with less air pollution. It would be nice to be able to see the future if we don’t change anything, then give a way for users to “unlock” the green filter, as other people have suggested.

Centrality of participation:
Making it a lens for social media is a nice invitation in and of itself. A solid invitation to this audience and very timely. The click to sign the petition is another invitation. The scroll up/down to move through time is confusing though> WHile it is a nice idea, it doesn’t look very discoverable in the interface you’ve laid out.

Rationale for design choices:
Your design criteria is well rationalized based on the audience. The poop emoji is a fun nod to the playfulness of the medium.

Layers of reading:
The bar chart is slightly off to me because I didn’t immediately understand what the x-axis was. Additionally, when they are scrolling through time I would have liked to see some indication of where in time we are as we move. Perhaps a small line chart of the overall AQI with an indication that moves about where we are in time? Another opportunity to include a deeper layer reading would be to include some light information about *why* the air quality decreases in the future (if they’ve taken action) when they scroll into the future.

Appropriate data use:
I’m curious what your endpoints were for least vs. most polluted. Ie. How many poop emoji show up if you are the worst day ever recorded in Delhi? Is the image of yourself unseeable? I like the mapping of PMM2.5 to particles and red overlay to AGI – it is a nice way to capture multiple metrics of evaluating air quality. How do you propose to compute the future impact based on the change you are getting the participants to support?

Suitability for audience:
Doing a filter for the younger audience is totally reasonable. It is playful and informative in design.

Narrative:
Setting yourself up as Greenpeace is a smart way to narrow your goals/audience and context. However, how come it doesn’t say Greenpeace on the filter anywhere? And does this match their brand styling? Another point is the scrolling through time it seems hard to see the differences. This might be an artifact of the way you have shown us the mock-up… perhaps in real-time it might be obvious. Another approach would have been to do a split-screen – where the left is one date and the right is today or something like that.

Call to action:
Getting them to sign the petition is nice, but I didn’t understand what the petition is for. I like the idea that when you scroll forward you can see the impact of the change, but this seems hard to predict and model – how do you propose to do this? I’d spend more time thinking about various calls to action and how/when you surface them.
