  5. Spatial Manipulation 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 demo1 [4] Dasher,http://www.inference.phy.cam.ac.uk/djw30/dasher/p0.html TAUCHI MMIG G. Evreinov 04_21 14.11.2003

  6. the left picture shows the EdgeWrite recognition 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.) Spatial Manipulation 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) [5] EdgeWrite: A Stylus-Based Text Entry Method Designed for High Accuracy and Stability of Motion TAUCHI MMIG G. Evreinov 05_21 14.11.2003

  7. Spatial Manipulation 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 TAUCHI MMIG G. Evreinov 06_21 14.11.2003

  8. Spatial Manipulation Keuning-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 TAUCHI MMIG G. Evreinov 07_21 14.11.2003

  9. Spatial Manipulation the method for rapid evaluation of new graphic templates for text input the 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 technique testing takes no more than two minutes per graphic template TAUCHI MMIG G. Evreinov 08_21 14.11.2003

  10. Spatial Manipulation 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 TAUCHI MMIG G. Evreinov 09_21 14.11.2003
