Interaction with wearable devices such as smartglasses is yet a problem. While the input space is limited, the interaction itself can have strong social implications in public spaces. Missing social conventions and technology apprehension can affect the users willingness to perform interaction in public. One possible way to address this, is to reach for preferably unobtrusive interactions that do not cast a lot of attention upon the user. Social acceptance may then rise due to continued exposure with the technology.
