Make the Popinator popinate

With time, money, and manpower there is no question engineers can make this novelty work.  This is engineer fun.  This puts a smile on peoples faces.  Its not directly solving any world problems, but my Mom always tells me how important it is to have a little fun every day, and she is 96.  As a business decision, is it worth the investment?  I'm estimating that it isn't worth a big corporate effort, but more like one or more people exploring it on their own, more for the interest and science than getting rich. 

As an engineering project, I would view the three primary functions as the "pop" command, the detection of desire to launch, definition of the specific location of the the target mouth,  and finally the targeting function to send the popped kernel to a specific location.  I would develop these threee functions somewhat  independently, and then integrate the three working functions.  The interfaces between the functions must be defined carefully as early as possible in the development process so that successful system integration will not require miracles to occur.  In this application, I would focus on high volume sensors from other fields for design simplicity, high reliability, and low cost.  I would not presuppose ultrasonic, vision, MEMS, or any other technology would be superior to any other without testing in this application.  I would look forward to systems testing and am willing to bring my own diet root beer to wash down some popcorn.

Yup, new picture, ChasChas. I figured it was time to stop using my driver's license photo.

New picture, Charles? That's the first thing that "popped" out at me. Not bad.

Could you make a game of chance out of the popinator - like spin the bottle?

Probably not, but you couldn't do it with "binaural microphones." A binary set (two) of microphones would be sufficient to get the speaker's azimuth but you would need another one (at least) to get elevation.

Then a classic set of artillery tables (such as were computed by the very first digital computers during the waning days of World War II) would define the aiming algorithm. As noted, compensation for popcorn variability would be necessary. Perhaps a MEMS scale to measure projectile mass would reduce this error. Correcting for air resistance variability would be more difficult of course.

I would make this thing use a digital camera face detect function for aiming the shooter and audio for the trigger. Perhaps you could combine the two to figure out which face if more than one. Even better, fire one at each face!

This would have really come in handy at last night's VP debate!

Two comments:  First I notice that the film shows every kernel hitting the "bull's eye."  I wonder how many hours of video they had to edit to catch that many perfect hits.  The speaker raises a very important point that because popcorn has a low density, random aerodynamic effects can dominate over Newtonian mechanics.

My second comment is to second those who point out that this is a silly idea to begin with.  Don't we engineers have enough real problems to solve?

In a previous life I designed toys and developed more than one prototype of a toy that responded to voice control. Some used algorithms running on nothing more than a PIC, others used more sophisticated devices. There was no mention of the budget for the thing. Nontheless, check out Sensory, Inc. for voice control IC's. We've used these for many (many) toys: http://www.sensoryinc.com/.

Though no one has asked I'll answer it anyway; I'm not interested in working on the thing.

It's an interesting idea, but it's a solution looking for a problem. I suppose a popcorn company could use it in commercials and for trade shows, but I don't see it as a commercial product.

Meh. We do it every day with hearing aids that have inter-ear coordination (via ear-to-ear RF communication), which among other things allows the directional microphones to "steer" towards the voice and away from the noise.

It may work in an acousticly dead room, but the problem of echos and background noise are real world problems that would be hard to address.  cool idea though.
