Reflection
As the project draws to a close, looking back on the entire journey, our ideas have undergone tremendous iteration and metamorphosis. First of all, we think the most important thing we've learned is my understanding of sustainability. In the beginning, we only superficially stayed on the level of greenery and environment, and changed the dynamic of the lobby through "visual guidance". Meredith's question in the first class presentation gave us a lot of inspiration, "why adding more plants to the space is sustainable?" We recognize that there are many invisible energy costs behind green plants, such as human resources and water resources, that imperceptibly place an additional energy burden on the entire space, which is, in a way, the opposite of sustainability. In our interview with Professor Piantella, it became more clear to us that many people over-embellish this concept. It's actually perpetrating a model of living that is not sustainable. It's actually perpetrating a model of living that is not sustainable. So we refined our thinking and jumped out of the stereotypical rabbit hole.

Second, we recognize the importance of user surveys and surveys to evaluate and improve the solution. At first, we focused our attention on the digital wall of the lobby from a preconceived perspective. While the digital wall is certainly a place that deserves a makeover, we have neglected to consider people's behavioral states and consciousnesses. In the interviews and interviews with students, we found that due to the structure and location of the space, people rarely pay attention to the content on the digital wall, and at most they only glance at it. And, most people only enter buildings for a short time and have time to linger when they leave. Therefore, adding some interaction in the outgoing way will attract more attention. And everyone agrees that the lobby lacks the NYU element, like a regular building. People were more interested in transforming the ambience of the lobby than in adding sustainable design. Based on the different feedback, we began to explore sustainability at a more specific level. After several group meetings, we decided to explore sustainable expression under humanistic care. We have found that the feature of the 370 jay building is the sustainable use of energy. As the owners of the building, we believe that people should be aware of this information. In addition, people are also very interested in the sustainability information of the building in the reply of the survey. Most of the majors in this building are related to technology, so we wanted to use interactive media to show the warmth and creativity of technology and to make people more aware of the environment. In the final solution, we didn't do too much visual guidance because we didn't want to force people to experience, passively accept. We are just offering you an alternative. If it gives you a good experience or feedback, saying nothing can subtly change your thoughts and behavior in some way, maybe the next time you're standing in an elevator, do you suddenly think, "Can I take the stairs?"

​In the end, we really enjoyed exploring different materials. At first our ideas were limited to the use of composite pictures to show our transformations of a wall, but as we went on deeper we decided to use the knowledge we had learned to vividly restore and present our ideas. In another class, our group members found that the projector worked well for visual presentation, so we decided to incorporate interaction into the staircase, which also met our expectations. Depending on which sensor we are using, we add real-time data visualization to the rendering.

The biggest difficulty throughout the project was how to make sustainable information accessible to people independently, and to break away from the stereotype of sustainability. We do not want information to simply scroll across the big screen, which will have no effect. Based on the survey, we found the behavior of taking the stairs. This is an "environmentally friendly" option in itself, so we thought we could encourage people to adopt a new way of travel while introducing relevant knowledge to complement each other. But in designing the whole experience, we've been very careful to make sure that we're not judging or negating your choices, what we're doing is just telling you, there's a new experience here that's going to help you and me and the environment, do you want to try it, that's all.

As for the failure, it is a pity that due to time constraints, we have not been able to generate our own digital blossom, which is currently presented as gif playback. So for visualization to grow out of this project, we first want to leverage the visualizations we've already created, or we can create a platform for you to contribute and showcase your unique personal visualizations. 

Future Outreach 
And while we are currently only designing around the staircase, there are many areas in the lobby that deserve to be redefined and transformed. This week we also had the pleasure of getting in touch with Mr. Andrew Repoli, NYU's Director, Global Facilities & Construction Management (AR) for an interview. During this interview, we learned a lot about the building's historical background and some of its amazing sustainable designs, which unfortunately most people do not know. So first, we hope to add interactive displays and headsets to the lobby in the future. This interesting knowledge can be played on the screen when someone is wearing a headset. We believe this will be a meaningful design. According to Mr. Repoli, the building is designed and operated efficiently in terms of refrigeration, so our sustainable prompts can be extended to this area in the future. In addition, we hope to emphasize the existence of Clive Davis gallery in the lobby and give it the opportunity to become a landmark of Jaystreet. Finally, with regard to the existing digital wall in the lobby, we are also very interested in the idea of an audio visual and interactive building directory, hoping to display the characteristics of different specialties and floors through different interactive ways and modules. Thus, the interaction projection can be used in several directions, especially the exit part. If it could show current weather conditions, subways and other useful information, it would be very intimate and convenient for everyone. Would it also save energy if fewer actions and less network data were used? In addition, we will continue to iterate on the display screens we've designed for the empty walls behind the elevators to show you exactly what's going on inside the building.
