Mobile Terminal Input Through Cooperative Display And Hard Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal devices face challenges in input actuation due to limited touch panel area and increasing number of touch keys, making it difficult for users to perform inputs accurately and efficiently, especially when voice recognition is involved, as the user cannot visually confirm the correct assignment of touch keys.
Innovation Solution
A cooperative system comprising an information processing device and a mobile terminal device that allows for detachable connection, where the information processing device includes hard keys with concave shapes and dedicated display areas for icons, and the mobile terminal device displays operational state information, enabling intuitive input through shared display and tactile identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of touch keys is increased to provide more functions, then the functionality of the mobile terminal device is improved, but the area available for each touch key becomes smaller, making it difficult for users to accurately identify and actuate the keys
Solution Approach 1:
The patent combines the mobile terminal device with an information processing device (such as a car navigation system), allowing the information processing device's display and input units to be used in cooperation with the mobile terminal device. This merging enables the mobile terminal to leverage the larger display area and physical input units of the external device, thereby maintaining ease of operation while expanding overall functionality.
Solution Approach 2:
The patent introduces an intermediary system where the information processing device acts as a mediator between the user and the mobile terminal device. The intermediary provides additional display area and input mechanisms, allowing users to interact with the mobile terminal's functions through the external device's interface, thus resolving the contradiction between having many functions and maintaining easy operation.
2Productivity
If voice recognition is used to perform input without checking key layout, then input speed is improved, but the user cannot visually confirm correct recognition and key assignment, leading to potential errors
Solution Approach 1:
The patent implements a feedback mechanism where the information processing device's display unit visually presents the recognized voice input and the assigned touch key or function to the user. This feedback allows users to verify the correctness of voice recognition and key assignment before execution, thereby maintaining high input speed while ensuring input accuracy through visual confirmation.
3Weight of moving object
If the touch panel area is kept small to maintain portability, then the mobile terminal device remains portable, but the number of touch keys that can be accommodated is limited
Solution Approach 1:
The patent makes the system universal by enabling the mobile terminal device to cooperate with an external information processing device. The mobile terminal maintains its small, portable form factor, while the external device provides additional input capabilities and display area. This multi-functionality allows the system to offer both portability and access to numerous functions through the combined capabilities of both devices.

AI summary
According to the present invention, a specification unit (810) specifies an operational state including an operational mode of a mobile terminal device (800), and sends the specified result to a display control unit (820). When an information processing device (700) and the mobile terminal device (800) are performing cooperative operation, if it is discovered by means of the specification result that the operational mode of the mobile terminal device (800) changes, the display control unit (820) generates, according to the change of operational mode, display designation including icons to be displayed in the first display areas 721 of the information processing device (700) and there shapes. And the display control unit (820) transmits the generated display designation to the information processing device (700). Due to this, it is possible to employ the input unit of a different information processing device in an appropriate manner when performing actuation input to the mobile terminal device.
