Method and device providing multimodal input mechanism

A device for multimodal input mechanism, the device comprising:

• a memory storing instructions;
• one or more Input/Output (I/O) interfaces;
• and
• one or more hardware processors coupled to the memory via the one or more I/O interfaces, wherein the one or more hardware processors are configured by the instructions to:
• detect an event triggered by a user from a device to receive a sequence of characters selected from a plurality of characters through the multimodal input mechanism, wherein the plurality of characters comprise a combination of alphanumeric and special characters, and wherein the plurality of characters are divided into a plurality of character sets;
• activate the multimodal input mechanism on detection of the event, the multimodal input mechanism comprising:
• providing an option to the user to select an input modality pair from among a plurality of modalities, wherein the input modality pair comprises a first modality and a second modality, and wherein the plurality of modalities are preconfigured in the device and comprise a touch mode defined by a set of touch based gestures, a motion keyboard mode defined by a set of device tilt based gestures, an air gesture mode defined by a set of virtual gestures and a voice mode defined by a set of voice commands;
• setting:
• a) the first modality for selecting a character set among the plurality of character sets defined for the multimodal input mechanism;
• and
• b) the second modality for inserting a character among a plurality of characters from the character set selected by the user;
• and
• receiving the sequence of plurality of characters by enabling user to insert each character of the sequence, wherein inserting each character comprises:
• a) enabling user to select the character set to which each character belongs on detecting a first modality gesture among a set of first modality gestures defined for the first modality corresponding to each of the plurality of character sets, and wherein a first predefined vibration pattern, providing a haptic response to user, indicates the character set that is currently available for selection;
• and
• b) enabling the user to select the character corresponding to each of the plurality characters on detecting a second modality gesture among a set of second modality gestures of the second modality defined for each of the plurality of character in the selected character set, and wherein a second vibration pattern, providing the haptic response to the user, indicates the character from the selected character set that is currently available for selection.

One or more non-transitory machine-readable information storage mediums comprising one or more instructions, which when executed by one or more hardware processors causes a method for multimodal input mechanism, the method comprising:

• detecting an event triggered by a user from a device to receive a sequence of characters selected from a plurality of characters through the multimodal input mechanism, wherein the plurality of characters comprise a combination of alphanumeric and special characters, and wherein the plurality of characters are divided into a plurality of character sets;
• activating the multimodal input mechanism on detection of the event, the multimodal input mechanism comprising:
• providing an option to the user to select an input modality pair from among a plurality of modalities, wherein the input modality pair comprises a first modality and a second modality, and wherein the plurality of modalities are preconfigured in the device and comprise a touch mode defined by a set of touch based gestures, a motion keyboard mode defined by a set of device tilt based gestures, an air gesture mode defined by a set of virtual gestures and a voice mode defined by a set of voice commands;
• setting:
• a) the first modality for selecting a character set among the plurality of character sets defined for the multimodal input mechanism;
• and
• b) the second modality for inserting a character among a plurality of characters from the character set selected by the user;
• and
• receiving the sequence of plurality of characters by enabling user to insert each character of the sequence, wherein inserting each character comprises:
• a) enabling user to select the character set to which each character belongs on detecting a first modality gesture among a set of first modality gestures defined for the first modality corresponding to each of the plurality of character sets, and wherein a first predefined vibration pattern, providing a haptic response to user, indicates the character set that is currently available for selection;
• and
• b) enabling the user to select the character corresponding to each of the plurality characters on detecting a second modality gesture among a set of second modality gestures of the second modality defined for each of the plurality of character in the selected character set, and wherein a second vibration pattern, providing the haptic response to the user, indicates the character from the selected character set that is currently available for selection.
