This week I worked on updating the system diagram to reflect recent decisions, and on finishing three mock-up images. Here is the current system diagram. Major changes include reducing the number of participants to one, adding speakers, changing the run-time environment to Windows, and using one of the ghost figures from Lu's designs. The mock-up images are like 'fake screenshots' of a potential outcome for the display visuals. These serve as 'work in progress' discussion points for our creative process. Participant sees themself at the beginning of the interaction: Participant spots a disembodied skeleton hand - maybe they can use it! The background has changed to reflect the passing of time. The moon has almost set! Soon the sun will rise and the interaction will be over.
