1. An electronic apparatus with haptic output, comprising:
a camera component;
an ultrasonic component; and
a processing unit, coupled to the camera component and the ultrasonic component, wherein the processing unit is configured to:
repeatedly receive a detection image through the camera component,
continuously analyze the detection image to obtain a plurality of operating positions,
respectively generate a first control signal and a second control signal corresponding to two operating positions, which are continuously obtained and different from each other of the plurality of operating positions,
output the first control signal to the ultrasonic component, and sequentially generate a plurality of first oscillating points to form an oscillating clump at former of the two operating positions based on the first control signal through the ultrasonic component,
output the second control signal to the ultrasonic component, and sequentially generate a plurality of second oscillating points to form another oscillating clump at latter of the two operating positions based on the second control signal through the ultrasonic component, wherein
the plurality of second oscillating points have gradually-decreasing or gradually-increasing oscillation intensities in a rotation direction according to a distance change between the two operating positions.
