b. Design Scenario

Bob places Dogg0 in the room. Truus notices that Dogg0 looks familiar, it reminds her of a dog. Dogg0 wakes up, looks around and notices Truus, plays an "exited" sound and starts wagging its' tail. Dogg0 drives towards Truus and looks up to her. Dogg0, shows her expressions that stimulate her to interact with it: blinking, wagging its' tail and turning its' ears. Truus interprets these expressions as a sign that Dogg0 wanting to be pet, so she pets it on the head. Dogg0 plays a warming sound, turns its' LEDs to a warm orange color, closes its eyes, slowly wags its' tail and moves its' head down. Truus continues to pet it. It reminds her of her own dogs.

After Truus has stopped petting Dogg0, it re-enters the "asking for interaction"-state by looking back up, turning its' ears, changing its' LEDs to a bright purple, blinking and wagging its tail rapidly. With the suggestion of Bob, Truus claps, which initiates Dogg0's dance. Dogg0's LEDs turn a bright blue, Dogg0 makes a little bow, plays a high tone, blinks, starts wagging its' tail rapidly, turns around and moves forward. Then, it starts to rotate and move backwards, rotate and move forwards. It does that a few times while rotating its ears, Changing its' LEDs to different colors and blinking its eyes. All of these movements and expressions lift Truus' spirits and might even stimulate  her to dance together with Dogg0. She continues clapping and Dogg0 continues dancing, lifting her mood. 

At the end of the sequence, after Truus has stopped clapping, Dogg0 turns around, drives away and goes to sleep. It does this by stopping, moving its' head down, switching off its' LEDs, closing its' eyes and rotating its' ears back. Truus is tired from the interaction and falls asleep in her armchair. Bob might leave Dogg0 in the room to brighten Truus' day another time, or he might take it and introduce it again for a next interaction.
