Head-mounted display, tapping input signal generating method and non-transitory computer readable storage medium thereof

A tapping input signal generating method, being adapted for use in an electronic apparatus, wherein the tapping input signal generating method comprises the following steps:

• determining a virtual plane position based on a plurality of real-time images including a plurality of fingers of a user;
• calculating a distance between each of the fingers and the virtual plane position to set a displacement threshold of each of the fingers based on the real-time images;
• calculating a displacement distance corresponding to each of the fingers based on the real-time images;
• determining whether there is a first finger among the fingers corresponds to a tapping pattern based on the displacement distance and the displacement threshold of each of the fingers;
• determining whether a sensing signal received from a wearable device matches a tapping gesture of the first finger in response to having the first finger among the fingers corresponding to the tapping pattern;
• and
• generating a tapping input signal corresponding to the first finger in response to the sensing signal matching the tapping gesture of the first finger.

A non-transitory computer readable storage medium, having a computer program stored therein, wherein the computer program comprises a plurality of codes, the computer program executes a tapping input signal generating method after being loaded into an electronic apparatus, the tapping input signal generating method comprises:

• determining a virtual plane position based on a plurality of real-time images including a plurality of fingers of a user;
• calculating a distance between each of the fingers and the virtual plane position to set a displacement threshold of each of the fingers based on the real-time images;
• calculating a displacement distance corresponding to each of the fingers based on the real-time images;
• determining whether there is a first finger among the fingers corresponds to a tapping pattern based on the displacement distance and the displacement threshold of each of the fingers;
• determining whether a sensing signal received from a wearable device matches a tapping gesture of the first finger in response to having the first finger among the fingers corresponding to the tapping pattern;
• and
• generating a tapping input signal corresponding to the first finger in response to the sensing signal matching the tapping gesture of the first finger.
