There you have it folks...

The site does not say how it does tracking, but some articles say that it is using "motion detection". I suppose that means that it integrates the output from an accelerometer.
I have bought and tried a cheap "finger mouse" before. It was also strapped onto the index finger, but with a simple velcro strap, and it had the mouse buttons in same position, but it require me to touch the mouse to the desk to track. Cheap crap, not wireless, but I might be able to reuse the innards for some project ...
I wonder how it would feel after prolonged use... One advantage with using a mouse is that you can rest your arm on the table and get very high precision with only slight finger movements.
I also am afraid that the strap would break pretty soon. That would give an advantage to volumetric sensing (such as Leap Motion) or an overhead camera (like a guy at Microsoft Research did.. bah, I can't find the video now, sorry).

It looks like wearing this device would cause the cursor to move constantly while you are typing, which I would strongly dislike.

That would be quite distracting.
And yes, it's using accelerometers or a gyro.
There has been a few mice with them over the years for presentations, the better ones work fine, but don't expect precision movement.

The site is rubbish and the information is ambiguous.
Apparently, the pictures on the site, the press previews (under the Press heading) and the videos (different videos on the site and in press previews) show different prototypes and 3D renderings that work in different ways.
In the CNET article (http://www.cnet.com.au/mycestro-the-wearable-finger-mouse-339343585.htm), it says that you have to touch the button strip to make it start tracking.
Mycestro's site has a quote of the CNET interview that says this, but it is in a large font somewhere below the FAQ so it is easy to miss. This article also says that you click by "tapping" a button.
The FAQ says that you will be able to configure the relative size of the "buttons" on the touch-strip.
Somewhere (I can not again find where...) it says that the buttons are tactile...
Hmm... so if I understand things correctly, you would enable the device by touching the button-strip and you would click by pressing a button. I suppose that the button-strip is like the surface of the "Apple Magic Mouse" where there is actually only one physical switch and whether the click is left or right is determined on if you touch the surface on the left or right side.
... but I could be wrong.
Ah, I'll send them an email to get them to clarify this!

I think it would be a failure.
One very simple thing. Most people hate black cherry switches. They say these are too heavy.
How many black cherry switches are you going to wear all the time on your finger while typing?
gesture science is improving leaps and bounds. in a few years, you can just get cameras to track your index finger pointing at the screen. If you click your fingers, they will probably double click for you. Why would you need to wear something?
