Implementation and evaluation of the Daisy Wheel for text entry on touch-free interfaces

Augmented Reality and Virtual Reality systems have become more popular, in part, thanks to the development of cheaper technologies, which make them more accessible to all kinds of users. Some of these systems try to find means of interaction free from the use of additional devices (keyboards, controllers or wearables), these are referred to as Touch Free Interfaces. Nevertheless, some activities are limited because of the design of current interfaces, such is the case of text entry, which isn't efficient when it's done using a QWERTY keyboard within a Virtual Reality or Augmented Reality environment. This paper proposes the use and evaluation of an interface which makes it easier to entry text on these systems through the movements of the hands.
