Solution Overview

Problem

Existing mobile terminals are inconvenient for controlling multiple digital devices connected through them, as users need to individually manage each device, which limits the efficiency of controlling and executing speech commands across connected devices.

Innovation Solution

A mobile terminal equipped with speech recognition capabilities allows users to input commands that can be interpreted and executed across connected devices, enabling convenient control and modification of external devices without physical contact, using a speech recognition mode that converts voice commands into actionable instructions for connected devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users control each digital device individually, then each device can be managed precisely, but the operation becomes inconvenient and time-consuming

Engineering Contradiction:
Improveconvenience of controlling multiple devicesVSAvoidtime required to control each device separately
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges multiple device control functions into a single unified interface on the mobile terminal. The touchscreen display consolidates control options for camera, media player, and other connected devices, allowing users to manage multiple devices through one centralized control point rather than individually controlling each device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mobile terminal is designed with universal control capabilities that can manage various types of digital devices (camera, media player, audio equipment) through a single platform. The system provides multi-functional control where one device serves as a universal remote for multiple external devices, eliminating the need for separate control mechanisms for each device type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If speech recognition is used to control devices, then hands-free operation is enabled, but command accuracy may be reduced requiring modification capabilities

Engineering Contradiction:
Improvehands-free control capabilityVSAvoidaccuracy of speech command recognition
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system implements feedback by displaying the recognized speech command on the touchscreen display. This allows users to verify what the system heard and understand the intended action. The feedback mechanism enables users to correct misrecognized commands before execution, improving overall command accuracy while maintaining hands-free operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The touchscreen display serves as an intermediary between the speech recognition system and the user. It mediates the interaction by showing recognized commands and providing visual confirmation, allowing users to review and modify speech inputs. This intermediary layer bridges the gap between imperfect speech recognition and precise device control.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A mobile terminal and controlling method thereof are disclosed, by which a user can control a mobile terminal and each device connected to the mobile terminal using a speech via the mobile terminal while the mobile terminal and external digital devices are connected together via a prescribed interface. The present invention includes a display unit, a user input unit, a microphone, a communication module and a controller, when connected to at least one external device via the communication module, if a electric signal corresponding to a user's speech command is inputted via the microphone in a speech recognition mode, recognizing the speech command by analyzing the electric signal, the controller controlling the recognized speech command to be displayed as a prescribed graphic user interface (GUI) on the display unit.
