  • Publication number: 20140173496
    Abstract: A method for transition between sequential pages displayed by an electronic device which runs a slideshow presentation application program such as Microsoft® PowerPoint. The method includes the steps as follows. Generate input signals from a user tracing a simple shape with his fingertip on the screen. Identify the traced shape. The type of transition display property which is associated with the predefined shape is acquired when the traced and identified shape is substantially similar to a predefined shape stored in the storage unit. The transition to next displayed page is displayed with the acquired type of display transition property. A related electronic device is also provided.

  • Publication number: 20130184595
    Abstract: Methods are presented for determining pulse transit time (PTT) and/or pulse wave velocity (PWV) of a subject by application of parametric system identification to proximal and distal arterial waveforms. The two waveforms are measured from the subject. A system is defined that relates the proximal arterial waveform to the distal arterial waveform (or vice versa) in terms of the unknown parameters of a parametric mathematical model. The model parameters are determined from the measured waveforms using system identification. PTT between the proximal and distal arterial sites is then determined from the system model. PWV may also be determined by dividing the distance between measurement sites (D) by PTT.

  • Publication number: 20130120430
    Abstract: A text reading guide method for an electronic device including a display screen and a storage unit is provided. The storage unit stores a database recording a number of feature values of images and a plurality of coordinates. Each set of coordinates corresponds to a display region and is associated with a feature value. The method includes the steps of capturing an image of finger of a user; extracting a finger image feature value from the captured finger image; searching the database to find a matching finger image feature value, and retrieving the coordinates associated with the finger image feature value; determining the display content on the display region corresponding to the retrieved coordinates; and displaying the determined contents in a manner of highlighting on the display screen. An electronic device using the method is also provided.
