Get Pregnant at SIGGRAPH 2011

Well not literally, but you certainly can experience what it feels like to be pregnant at SIGGRAPH 2011 this August in Vancouver. "Mommy Tummy: A Pregnancy Experience System Simulating Fetal Movement" is one of 23 interactive Emerging Technologies that will be featured at SIGGRAPH.

This interactive system simulates pregnancy through the use of a Mommy Tummy jacket which transmits the fetus’s temperature, movement, and heartbeat. Also, by rubbing the jacket you are able to communicate with the fetus. Within a few minutes, the jacket's weight and size change, simulating fetal growth over nine months. An auxiliary screen displays the condition of both the fetus and the mother in each simulated month with a 3D model of the fetus. The moods and activity of the fetus are displayed in a natural manner to simulate normal fetal development.

There are two types of fetal movement: kicking and wiggling. According to the inventors, achieving a kicking simulation is not as difficult as a wiggling simulation. It was achieved by using a technique inspired by the tactile funneling illusion (PhS) initially discovered by Georg von Bekesy as a type of illusory tactile sensation that arises between two points of simultaneous vibration or electric stimulation. Using PhS, Mommy Tummy simulates a wiggling sensation through continuous, temporally displaced operation of multiple air actuators.

When the user moves violently, the fetus enters a bad mood state and makes intense, jerky movements. Conversely, when the user caresses the abdomen, the fetus enters a good mood state and makes steady movements. Heavy physical exercise is discouraged until a stable period is reached. We wonder if a birth simulation is next up for these researchers - who are listed below.

  1. This seems very amazing.I have never heard about this before.I would like to experience this actual artificial experience of pregnancy.
    I enjoyed your blog very much.

  2. We are a small group of people who want to help as many women (and men) as we can in their pregnancy quest and experience. Of course, the most important is the community and the support that people in the same position can give to each other.

  3. My name is SARAH, my partner and I have been trying for a baby for over two years now, We were going to a fertility clinic for about 5 months before somebody told me to contact this spell caster who is so powerful, so i contacted him at this email;(agbazara@gmail.com), for him to help me get prenant,And I'm glad we came to DR.AGBAZARA TEMPLE, Because his pregnancy spell cast put us at ease, and I honestly believe him, and his powers really helped us as well, I am thankful for all he has done. contact him via email at: (agbazara@gmail.com) if you are trying to get a baby, he has powers to do it, he has done mine,
