Prompt Method and Portable Device

A prompt method implemented by a portable device adsorbed on a magnetic holder, comprising:

• controlling a display of the portable device to be in an off state;
• detecting that a parameter related to a magnetic induction intensity indicative of adsorption between the portable device and the magnetic holder deviates from a preset threshold range;
• activating the display of the portable device and outputting a voice prompt;
• and
• displaying, on the display, prompt information for moving the portable device.

A portable device, comprising:

• a display;
• an audio output apparatus;
• a magnetic field sensor comprising:
• a magnetic sensitive element configured to sense a magnetic induction intensity proximate to the portable device from a magnetic holder ;
• and
• a signal processing circuit coupled to the magnetic sensitive element and configured to convert the magnetic induction intensity into a digital signal;
• a processor coupled to the display, the audio output apparatus, and the magnetic field sensor, wherein the processor is configured to:
• control the display to be in an off state;
• determine, based on the digital signal, a parameter related to the magnetic induction intensity indicative of adsorption between the portable device and the magnetic holder;
• detect that the parameter related to the magnetic induction intensity deviates from a preset threshold range;
• activate the display of the portable device and output a voice prompt using the audio output apparatus;
• and
• display, on the display, prompt information for moving the portable device.

A portable device, comprising:

• a display;
• an audio output apparatus;
• a magnetic field sensor comprising:
• a magnetic sensitive element configured to sense a magnetic induction intensity proximate to the portable device and of a magnetic holder;
• and
• a signal processing circuit coupled to the magnetic sensitive element and configured to convert the magnetic induction intensity into a digital signal;
• a processor coupled to the display, the audio output apparatus, and the magnetic field sensor, wherein the processor is configured to:
• display an interaction interface of the portable device on the display, wherein the interaction interface comprises an unlock interface, a home screen, a standby screen, a lock screen, a non-home screen, or an application interface;
• determine, based on the digital signal, a parameter related to the magnetic induction intensity indicative of adsorption between the portable device and the magnetic holder;
• detect that the parameter related to the magnetic induction intensity deviates from a preset threshold range;
• skip displaying, in response to the detecting, the interaction interface of the portable device on the display and output a voice prompt using the audio output apparatus;
• and
• display, on the display, prompt information about moving the portable device.
