The element I found the most interesting was one about persistance. I really like this view since it is unique and can really feel as a very human thing. However, I want to move the boundaries a bit and flip this one around to explore the other side of this characteristic; giving up. Now, the reason why I think this angle is also interesting, is because giving up is something very human as well, and we usually really encourage each other to not give up and keep going. I want to research how far this "giving up on someone" can go with artificial creatures. To take this on a bit of a more positive note, I will look at encouragement and giving up as a combination.
An example of such a creature could be one that travels to the top of a mountain. This could just be a little creature on a slope. When it receives high volume input it slowly travels the mountain, together with giving a little sound effect of its fatigue at that point. The closer the creature gets to the top the slower it goes. When it receives no input volume anymore, it will immediately give up, and slide all the way down to the beginning. Also, when the creature is really close to the top, it will start to stop moving almost, maybe even express that it can not continue anymore. This will then really test the emotional connection between the user and the creatures adventure. However, if it is encouraged long and effictively enough, it will reach the top, but it will require some determination from the user.
Additionally, the robot could make sad noises when it gives up, trying to indicate to the user that they feel let down or given up on. This way, this creature can flip the switch in both directions, where the giving up is a central element for both the creature and the user.
