Important Notice: Eliza is not a real psychotherapist. It simply mimics how a psychotherapist would interact with a patient. In addition to the original ELIZA our version features various speech output options. Eliza is a mock Rogerian psychotherapist and the original program came from Joseph Weizenbaum in MAD-SLIP for project MAC at MIT on an IBM 7094. cf: Weizenbaum, Joseph ELIZA - A Computer Program For the Study of Natural Language Communication Between Man and Machine in: Communications of the ACM; Volume 9, Issue 1 (January 1966): p 36-45 The first version in BASIC was written by Jeff Shrager in 1973 and converted to MITS 8k Basic (later to become Micosoft BASIC) by Steve North in 1977. It originally appeared in Creative Computing July/August 1977. This app is based on the Atari version published in Big Computer Games 1984. Some enhancements added based on the JavaScript implementation by Norbert Landsteiner 2005; http://www.masserk.at

Look at the Garage Kit at the table. Look at the cups which get along with you. Have you ever thought about letting them "Talk" one day? With Doodle Talk, you can take a picture of the those objects, and then freely choose the facial features, or add some graffiti, and then, the miracle is happenning. Those objects can turn their eyes as your camera moves, and open their mouths as your talking volumn. Yes, they are 'alived'. Finally, you can record it as a video and share this interesting scene with your family and friends. It's a funny app, inspired by my observations of things around you, you can use it for free, but there are some ADs banners in the corner, but it doesn't affect the functionality of the app. Of course, if you like this App, click on an ad or remove an annoying ads to support me to develop more interesting apps. Thank you, please~
