Portable Terminal In-Place Data Insertion with Touch-Positioned Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable information terminal devices, such as smartphones, allow new data to be added only at predetermined positions on the display screen, requiring laborious and time-consuming operations to move the data to desired locations, especially when dealing with long data or lists.
Innovation Solution
A portable information terminal device equipped with a display screen and operation elements that allow new data to be added at any desired position by touching a button, which displays a cursor and a button to enable data input at the desired location, and a keyboard appears for direct data entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If new data is added only at predetermined positions (top or bottom), then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The display screen is segmented into multiple data regions, and operation elements are selectively displayed at specific regions based on user interaction. When a user touches a data region, an operation element (button) is displayed only in that region, allowing data to be added at that specific position without requiring complex global operations.
Solution Approach 2:
The operation element (button) is prepared in advance but not displayed until needed. When a user touches a data region, the button is immediately displayed at that position, allowing the user to add data at the desired location without moving through complex menus or performing preliminary steps to position the input point.
2Productivity
If new data must be added at predetermined position and then moved, then the device complexity is reduced, but the loss of time increases
Solution Approach 1:
The operation element is displayed at the exact position where data needs to be added before the user performs the input action. This eliminates the time-consuming process of adding data at a predetermined position and then moving it, as the input point is prepared in advance at the correct location.
Solution Approach 2:
Instead of moving the operation element to the desired position after displaying it at a fixed location, the system inverts the approach by displaying the operation element directly at the desired position through user touch. This reverses the conventional flow and eliminates the moving step entirely.
3Ease of operation
If keyboard is simply displayed when button is touched, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The keyboard is displayed locally at the position where the user touched the screen, rather than appearing at a fixed location. This local display approach allows users to input data directly at the desired position without needing to move the keyboard or perform additional operations to position the input interface.
Solution Approach 2:
The keyboard is prepared for immediate use as soon as the user touches the screen. The system anticipates the user's intent to input data and displays the keyboard in advance at the correct position, eliminating delays and unnecessary steps in the input process.

AI summary
A portable information terminal device is provided that has a display screen, a function for displaying data on the display screen, and an operation element A that is displayed on the display screen and operates the display of the data, and whose display data can be viewed and edited. The portable information terminal device has a function of displaying, on the display screen, marks that allow new data to be added to all positions to which data can be added among a plurality of data (items) arranged on the display screen when the operation element A is touched. The marks are a cursor and an operation element B, and the operation element B is in the form of a button. The portable information terminal device has a function of adding or writing data at a desired position by touching the operation element B at the desired position for adding data. It has a function of making the mark disappear by touching a part of the display screen other than the operation element B.
