A computer generated holographic image. Very naturalized Computer synthesized speech. Able to move about the projected plane of a holographic image. The projected image is assumed to be line-of-sight with close range of the sit-down/within computer workstation. Advanced artificial intelligence software algorithms, vastly superior to state-of-the-art techniques within the computer industry.
Mister Smartie has not been seen since Astra's childhood. Even at that time, she felt she was a bit mature for the personality of Mister Smartie as the implanted computer tutor/companion. It is unknown if he has been activated since, or if he has lost the ability to respond to an activation request due to his operating system platform(s) aging. Given Augustus Furst's schedule (and age), he may have lost interest in maintaining the systems that keep Mister Smartie functioning.
