if cursor is moving into the “t”, rectangles corresponding to ‘ta’, ‘tb’,‘tc’, ...,‘tz’

appear in a vertical line like the first line

the heights of the rectangles correspond to the probabilities of these strings

according to the language model

algorithm before the

stylus is detected inside

one of the corners

once the stylus enters a

corner area, the corners

deflate for the duration of

the stroke (the right pict.)

for High Accuracy and Stability of Motion

onscreen keyboards are small and require the user to fix

attention on the keyboard rather than on the output

text entry (recognition) on a handheld device is difficult for

people with motor impairments (tremor, Cerebral Palsy

and fatigue)



marking menus and other forms of gesture input are being used in commercial desktop systems and in mobile devices

by analyzing mouse and pen flick gestures (5200 gestures), the high levels of angular error were revealed when using a pen-based input device to generate rightwards and leftwards gestures

the relatively long time taken to generate downwards gestures using the mouse

[9] Analysing Mouse and Pen Flick Gestures


Spatial ManipulationKeuning-Van Oirschot [10] investigated

cursor movements with an amplitude of 250

pixels, in eight different directions and with

three control devices: a mechanical mouse,

an optical mouse and an optical trackball,

to find characteristics of the cursor path

which could be used to create a prediction

algorithm on direction

the focus was on the mean curvature of

and the variability between the paths in

each direction

it can be concluded that on average cursor

paths are rather straight in all eight

directions and with all three devices

the variability of the paths depends on

direction, friction of the control device and

user



the method for rapid evaluation of new graphic templates for text inputthe method does not require learning of the new graphics, any layout or rules before testing, and is intended to evaluate the user’s capabilities regarding to the pen-based text entry techniquetesting takes no more than two minutes per graphic template



the average performance (left scale),

standard deviation and the amount of

copied images per second (right

scale)

the total times of the drawing (s),

the total length of tracks (mm) and

the number of copied images
