Stroke++: A new Chinese input method for touch screen mobile phones

Over the past few decades, users have been feeling clumsy inputting Chinese on mobile devices, partly because the layout of the keyboard/keypad is originally designed for inputting Latin alphabets. To improve this user experience, we propose Stroke++, a novel Chinese input method for touch screen mobile devices. More specifically, Stroke++ provides efficient keypad layout, a friendly user interface and a intelligent character/phrase candidate set generation algorithms. Stroke++ splits a Chinese character into multiple radicals. By leveraging hieroglyphic properties of Chinese characters, our method requires users to only input a subset of the radicals to identify the target character, making it much faster and easier to input Chinese on mobile phones. Our user study results show that Stroke++ outperforms most major Chinese input methods on mobile devices, including Stroke, Pinyin and Hand Writing Recognition (HWR), in terms of the input efficiency and usability. Moreover, we also demonstrate that Stroke++ offers a low entry barrier for Chinese-input novices.

Development of a touch probe based on five-dimensional force/torque transducer for coordinate measuring machine (CMM)

Systematic errors due to the pre-travel variation and the probe tip shape are irreducible to the traditional touch trigger probing systems. This paper describes the development of a probing system based on five-dimensional force/torque transducer for coordinate measuring machines. The compensation for pre-travel variation is accomplished through the five-dimensional force/torque information acquired by the integrated transducer and the stiffness matrix of the stylus. From the relationship between the obtained force/torque information and the geometrical shape equation, coordinates of the exact contact point immune from the contact error are acquired. After calibration, the combined measurement uncertainty is estimated to be less than ±0.3 μm.
