Dual-Terminal Drawing System with Segmented Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawing systems on tablet PCs face challenges in maintaining a large enough drawing area while allowing timely and accurate input of instructions, leading to reduced work efficiency due to the overlap of drawing and instruction input areas, especially with smaller display screens.
Innovation Solution
A drawing system comprising two terminal apparatuses, one with a larger display screen dedicated to drawing and another with a smaller display screen dedicated to instruction input, connected via near field communication to separate these functions and prevent accidental input errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If both drawing area and instruction input area are provided in one display screen, then instruction input is enabled, but the drawing area becomes small and accidental input occurs
Solution Approach 1:
The system divides the display device into two separate terminal apparatuses: one dedicated to the drawing area and another dedicated to the instruction input area. This segmentation allows each device to specialize in its function, preventing the drawing area from being reduced while still enabling comprehensive instruction input capabilities.
Solution Approach 2:
The instruction input terminal apparatus acts as an intermediary between the user and the drawing terminal apparatus. Instructions are input on the separate terminal and then transmitted to the drawing terminal, mediating the interaction without occupying the drawing display space.
2Area of stationary object
If the drawing area is increased on a small display device, then drawing space is improved, but instruction input becomes difficult and work efficiency deteriorates
Solution Approach 1:
By segmenting the functions across two terminal apparatuses, the drawing terminal can maximize its display area for drawing purposes while the instruction input terminal handles all parameter adjustments, line type selections, and color changes, thereby maintaining high work efficiency without compromising drawing space.
Solution Approach 2:
The instruction input terminal apparatus serves multiple functions: it displays the instruction input reception screen, receives various instruction inputs (line type, color, hue, vividness, brightness, degree of gradation), and transmits these instructions to the drawing terminal. This multi-functionality compensates for the separation of devices and maintains productivity.
3Adaptability or versatility
If the instruction input area is provided on the same display screen, then parameters can be adjusted, but accidental input occurs when the electronic pen enters the instruction input area during drawing
Solution Approach 1:
The instruction input area is extracted from the drawing display and placed on a separate terminal apparatus. This extraction eliminates the risk of accidental input during drawing operations, as the electronic pen used for drawing on the drawing terminal cannot accidentally trigger inputs on the separate instruction input terminal.
Solution Approach 2:
The separate terminal apparatus serves as an intermediary that receives instructions through its own interface (separate from the drawing surface), thereby mediating the input process and preventing direct accidental interaction between the drawing pen and instruction input area.

AI summary
A drawing system that can reserve a large drawing area and that can receive an input of instruction to an instruction input area at appropriately timing to make a drawing corresponding to the input. The drawing system includes a first terminal apparatus and a second terminal apparatus are connected to each other and communicating with each other. A display screen of a display device of the first terminal apparatus is dedicated to a drawing area, and a display screen of a display device of the second terminal apparatus is dedicated to an instruction input area. The first terminal apparatus includes a first position detection sensor, and a drawing is made in the drawing area provided on the display screen of the first display device according to instruction information from the second terminal apparatus and according to a drawing operation input received through the first position detection sensor.
