The main work:
According to the continuous advancement of the concept, we finally decided to screen among different sensors such as buttons, infrared, and M5. In this technical study, we tried to modify the code of different sensor affected parts. Summarize the experience and draw a conclusion: Although the infrared sensor can capture the precise position of the visitor, the light shows a large change. However, in a large space, it is difficult for visitors to accurately align with our sensor, and the instability is too high. It is difficult to ensure the stability of data transmission if the infrared sensor is installed on the wall or on the back of the chair, so we rejected this method.
Then we considered the option of installing buttons on the seats of visitors, but there are three problems that need to be solved: First, the soldered wires are not firm, and frequent movement and pressure may cause problems in the connection between the light strip and the button . Secondly, installing buttons on the seat or on the back of the chair can easily cause discomfort to the visitors. Finally, the pressure that the button can withstand is limited, and repeated heavy pressure may cause damage to the sensor.
Using the M5 sensor is currently the most stable and effective solution after testing. Its disadvantage is that visitors need to shake vigorously or perform large body movements to ensure interaction with the lights. At the same time, the data transmission of Wi-Fi will also have problems from time to time.
In this case, we decided to use the simplest button interaction to ensure the smooth progress of the exhibition. But at the same time, consider adding the M5 sensor to the exhibition to ensure more fun and enhance the interactive experience of visitors.
Questions & Reflections:
Unfortunately, the main reason why the original team’s ideas were difficult to realize was that we did not have a good grasp of technology. While exploring ways to interact, we are also actively looking for ways to embody our most important theme – smell. The difficulty of this problem lies in the synthesis and emission of odors.
