HMM for recognition of whole sentences. This system is
most similar to our system, but since it is intended for mobile
applications it requires the user to wear a glove, which is
not desireable in stationary use. Other approaches include
Zhou et al. [13] and Kim et al. [4] with the same restrictions
introduced by requiring to use handheld or wearable
devices. Text input for large displays was also investigated
by Shoemaker et al. [11], but for the Wiimote and without
handwriting recognition. In contrast, our system has no
such requirements and allows unrestricted text input.
