So Waterloo startup Thalmic Labs recently announced their first product, the MYO. Despite being tempted by many other cool tech preorders (such as the Leap Motion), this has been the first that has made me excited enough to preorder it.
Glass is a product that could see great benefit being paired with the MYO - currently Glass supports voice control, as well as a touchpad on the side. The problem with this is that talking to yourself in public is still not socially acceptable, and reaching up to touch your Glass constantly is almost just as awkward.
I think the potential for this - assuming the marketing video is somewhat accurate - is incredible, and I personally can't wait to get at the API and play around with the finished product.
