Small mobile devices such as smartwatches are a rapidly growing
market. However, they share the issue of limited input and output
space which could impede the success of these devices in future.
Hence, suitable alternatives to the concepts and metaphors known
from smartphones have to be found. In this paper we present
InclineType a tilt-based keyboard input that uses a 3-axis
accelerometer for smartwatches. The user may directly select
letters by moving his/her wrist and enters them by tapping on the
touchscreen. Thanks to the distribution of the letters on the edges
of the screen, the keyboard dedicates a low amount of space in the
smartwatch. In order to optimize the user input our concept
proposes multiple techniques to stabilize the user interaction.
Finally, a user study shows that users get familiar with this
technique with almost no previous training, reaching speeds of about 6 wpm in average.
