Electronic apparatus with segmented guiding function and small-width biometrics sensor, and guiding method thereof

An electronic apparatus, comprising:

• a processing module;
• a human-machine interface device electrically connected to the processing module, wherein the human-machine interface device comprises a display;
• and
• a small-width biometrics sensor electrically connected to the processing module, wherein the processing module executes a positioning algorithm and cooperates with the human-machine interface device to utilize the human-machine interface device to provide a human-machine interface, the human-machine interface comprises a virtual fingerprint image to provide an initial intelligent guide to guide different physical portions of a finger of a user to directly contact or approach the small-width biometrics sensor, so that the small-width biometrics sensor senses the finger to capture partial physical patterns of the finger, wherein the processing module executes the positioning algorithm to judge a geometric position of a first one of the captured partial physical patterns corresponding to a global physical pattern of the finger, and correspondingly maps the geometric position to the virtual fingerprint image of the display to establish a virtual geometric position on the virtual fingerprint image to display an enrolled first partial virtual pattern.

A guiding method of an electronic apparatus with a segmented guiding function, the electronic apparatus comprising a human-machine interface device and a biometrics sensor, and the human-machine interface device comprising a display, the guiding method comprising the steps of:

• displaying a global virtual pattern on the display;
• utilizing the biometrics sensor to capture a first partial physical pattern of a finger;
• utilizing a positioning algorithm to calculate a geometric position of the finger according to the first partial physical pattern;
• establishing a virtual geometric position and cooperating with the display to display the global virtual pattern and a first partial virtual pattern corresponding to the partial physical patterns;
• and
• performing a subsequent intelligent guide according to the geometric position of the finger to utilize the biometrics sensor to capture a second partial physical pattern of the finger.
