The Ice Cream Machine Visit: The interaction (see the interaction illustration below)
The interaction between human and the ice cream machine starts with the customer selecting and paying for the ice cream, which the process is operated on a screen and a computer. Then, the computer sends instructions to a robotic arm which it will perform a set sequence of making the ice cream and delivering it to the customer.
In the entire process, no human is involved except for the customer. But for maintainance, there has to be someone to fill up the supplies, such as milk and the cones.
The content on the screen is pretty simple: a button to start ordering, a payment system based on WeChat or Alipay, and then a finishing up animation.
In terms of sounds, it was very interesting that no computer-generated sounds were used at all. For the robotic arm, it makes basically no sounds, so the experience is mostly visual and psysical.
