    摘要: This invention relates generally to devices for location positioning and more particularly relates to a system for identifying an environmental source emitting a base frequency and waveform signal. A sensor (101) records an environmental source (105) emitting a base frequency and waveform signal, the signal being amplified (102), digitized (103), processed and compared (104) with a stored unique waveform characteristic. On the basis of the comparison result(s), location positioning and/or a device orientation may be determined. The invention further relates to a method and a computer readable medium containing a program for making a processor carry out the method.

    摘要: A method of pre-processing gesture signals comprises the step of Filtering one or more signal segments by applying an infinite impulse response (IIR) filter both in a forward and in a backward temporal direction, so as to produce a band-limited gesture signal. The method may further comprise the step of matching the forward and backward initial conditions of the IIR filters to avoid any transients. Unevenly or sparsely sampled gesture signals may be subjected to the preliminary steps of interpolating the sampled signal, resampling the interpolated signal at a relatively high resampling frequency, filtering the resampled signal, and optionally downsampling the filtered signal, so as to produce a gesture signal having a well-defined sampling rate. An additional compression step may be carried out. The method may be utilized in conjunction with handwriting recognition methods.

    摘要: An interactive method and system include at least one detector (210) configured to detect glazes of at least one viewer (250) looking at items (230, 232, 234). A processor (130) is configured to calculate gaze durations, such as cumulative gaze durations per item of the items, identify the most looked at item(s) in accordance with the cumulative gaze durations, and provide information related to the most looked at items. A display device (240) displays the information, a list of the most looked at items, representations of the most looked at items, and/or audio/visual show related to at least one item of the most looked at items. At least one item (290) and/or item representation may be displayed more prominently than others ones of the most looked at items and/or item representations.
