Again since we create the track and it has nothing to do with the audio once finished we are comparing apple and oranges.
First of all, audio has little to do with tactile, so perhaps you should address that fact. elements of sound can produce tactile, but they are different modalities. Tactile and vibratory information is received in special nerve endings in our skin. So of course tactile has nothing to do with audio.
Your product covers two modalities: motion and tactile, period. Saying "you create a discrete track has nothing to do with audio" has nothing to do with what I'm talking about. Secondly, you DO use elements of the soundtrack to create your motion track and you DO analyze the waveforms in the soundtrack to derive your custom track, which is corrrectly PART of the process.
You are 100% right about 20 to 20kHZ for Audio but our case it is slightly different. Tactile transducer have to be able to do this range because all they do is working of the audio and they need specs to sell their product...
This doesn't make sense at all. 1) Your case does not change human physiology. The human tactile system utilizes pacinian corpuscles in the skin which operate from approximately 1-500 Hz, this is fact. In real life we feel vibrations in this frequency range.
2) You say Tactile transducers have to work off of an audio track... Well this is the WEAKNESS of not having a discrete tactile track. That is my entire point for the last 7 years. There should be a custom tactile track. Nothing to do with sales, I don't care about sales, I only care about the truth and what best replicates real life. Yes, tactile transducers should also be running off of a disrete track which is why the leading tactile transducer companies also seek a discrete track from hollywood and are also in the process of trying to integrate with your coding system.
Again, you have a great product, the best overall in my opinion, but human physiology is human physiology and that is not up fpr debate, nor should be the design goals for both 3D motion as well as tactile.
Feeling up to 500 Hz is natural. I thnk it is wrong, terribly wrong for someone to say that it it is a disctraction to feel above 100 Hz. It simply means that your product has room for improvement. The design goal is to adequately cover the natural human range of vibratory sensation and that is 1-500 Hz. I will say it again: is it a distraction to hear above 5,000 Hz? Then why would it be a distraction to feel above 100 Hz? Your actuators are optomized for excursion, not frequency response. Like I said, if you could do 1.5 inch excursion and be able to have 500 Hz (or even 400 Hz) frequency response, I would consider that an improvement to adequately cover the human tactile range. Your encoder mentioned that foam in furniture absorbes higher frequency, well this is very true top some degree. There is *some degree* of attentuation of vibration with foam in furniture. This is all a part of the design process and something that Crowson addresses with manufacturers. Doesn't change the design *goals*.
The problem is that we should be discussing design goals here and what our our goals. Nothing to do with sales. Also tactile has nothing to do with audio since it uses skin receptors not the inner ear. A discrete tactile track would make the world of difference.
As I will say again, keep up the great work!
