Does technology drive new product development?

Whenever I see a new piece of tech come out to the market, and get mad publicity, it seems like there is always some crazy breakthrough research that is being used. How do I go about coming up with creative ideas for a useful, successful product, if I dont have the research to back it?

My current creative process involves using technologies that I found on the internet, mashing them together with preexisting ideas I have from my own experience, and part by part, work the idea in to a product. Then when I check online if anything like this already exists,  it turns out that it does, and it is 100 times better than the one I thought of. 

Either that happens, or my Idea for a cool invention is just so completely bizzare and unnecessary, that I can't justify turning i in to a reality. 

For a truly revolutionary idea, in the past people, with revolutionary ideas like Tesla, or Google, had truly original ideas, that were ahead of their time. Maybe taking inspiration from current new tech is the wrong approach,  Maybe the best way to do this is by changing the way I approach coming up with new Ideas. Maybe I can try avoiding new tech all for a while and see what happens. I draw inspiration from it, but If i stop that, perhaps I can  solely focus on looking for real world problems that need to be solved. That is, of course what most experienced people suggest. 

EEG vs EMG

In the last post, which was a while back, I was discussing some Ideas I had about the EEG headset and future technologies. The obvious problem with that is the fact that the tech is so underdeveloped due to our minimal knowledge of the human brain, that we cant hope to create any worthwhile robotic applications in the near future.

When I was discussing this, a friend of mine pointed me toward another similar tech called Electromyography, or EMG. It uses actual muscular stimulation as the data input instead of extrapolated neural signal patterns which currently have a very low degree of accuracy. With the EMG you place electrodes similar to the EEG electrodes, on specific locations on the muscle you are targeting. The sensor detects electrical signals sent to the muscles through nerves. This signal has a direct influence on the tension or relaxation of the muscle, and there is almost no way to interpret the signal incorrectly.

MYO is a product already available for purchase, that uses this tech for basic audio/video control, such as pause, play, fast forward, rewind. https://www.myo.com. It is an arm band that detects gestures, and relays them to any device with bluetooth. It is also open for developers, and people like https://www.youtube.com/watch?v=nDeOFxhH5lY have used it in basic robotics as well.

I want to go a step further, and use the EMG tech to develop a fully prosthetic robotic arm/robotic sleeve that slips on to the arm.

The device will be an extension of the user. There are endless possibilities. Spiderman webs shooting at one end? a specific hand pattern to unlock, improving security? hydraulic shoulder extension to punch harder? It'll be like Inspector Gadget! This is within our current capabilities as engineers.
