Up to this point our computers are designed with the direct intention of humaniod usage. But while currently there are no animals logging into Facebook, it may only be a matter of time before we design computers or machines to simply interact with our pets if only for own amusement. Of course, over time, other such functions can arise in animals machine interfaces, such as an automatic water/food dispenser, animal video conferences, or emergency contact systems for pets that are trained to act as guardians. In any case there are many applications associated with animals and interactive devices.
In the case of the BiDi gesture display it appears to me that a type of pet interface is hidden inside the potential "space of applications". BiDi video provides a level of interactivity that reduces the necessary precision of input - giving cats and dogs the ability to place their paws on or near the screen to interact with virtual objects. This level of interactivity may provide the same level of entertainment for the animal as playing with a physical toy.
Its not just about beings interacting with computers -- beings themselves ARE computers, in some ways...
Animal BiocomputersAccording to the research of Dr. John Lilly, the brain can be modeled as a biocomputer. This is certainly true for animal brains as well as humans - we all share an ability to internally represent the outside world, as perceived by our senses, to some degree. By interacting with a digital electronic computer, we expose our brains to hyperdimensional multimedia and enter into a feedback loop with human interface software (known also as Graphical User Interfaces).
Below is a clip from an experiment that we conducted on a domestic canine. being subjected to audio visual brainwave entrainment using isochronic audio tones and strobing lights in the theta brainwave frequency range. Approximately 6 Hz. The program responsible was 2 by (www.Transparentcorp.com). Though no apparent conclusions could be drawn as a result of this particular experiment.
