Has anyone outside HiWave experienced this technology to describe the effectiveness of the approach? Obviously external speakers produce sound which passes through the open outer ear (pinna) to the eardrum. Such speakers also disturb everyone else in the vicinity. Since the pinna is relatively flexible, direct stimulation would not seem to be a very efficient way to convey sound of any significant frequency range to the inner ear.
Good development but the complete characterization of the device will let the user know about the response of the device. Generally this kind of device will throw high frequency sound loudly as compared to low. Existing speakers are producing hi-fi sound, so this good new piece of speakers will have to compete with it.
It sounds like an incredible technology. I can't wait to see the first protocol product or the reference design coming out to the market. I guess Google eyewear will come to reality in fairly short amount of time. Question is how to provide the current to drive the speakers and display. If battery is needed, will the energy storage technology catch up soon enough?
