Remote Control Interface for Touch Device Attribute Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when controlling large touch devices due to the need for extensive movement to reach and interact with various functions on the screen, especially when functions like changing text color or navigating menus, which can disrupt teaching or presentation activities.
Innovation Solution
A mobile apparatus with a user interface window that allows selection and transmission of input attributes such as color, font, size, thickness, and eraser for writing and drawing operations on a touch device, enabling easier control and reducing the need for physical movement by allowing attribute changes through a remote interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large touch device is used for teaching or presentations, then the display area and visibility are improved, but the ease of operation deteriorates due to frequent movement required to reach different functions
Solution Approach 1:
A remote control device is introduced as an intermediary between the user and the large touch device. The remote control transmits touch input coordinates and selected input attributes (color, font, size, etc.) to the touch device, enabling users to control functions without physically approaching the large screen.
Solution Approach 2:
The remote control device creates a simplified copy of the essential control interface. Instead of replicating the entire large touch interface, the remote provides a condensed version with key functions and attributes, allowing users to access all necessary controls from a manageable size device.
2Adaptability or versatility
If all control functions are integrated on the touch device screen, then the device functionality is improved, but the user convenience deteriorates due to the need to traverse large screen areas
Solution Approach 1:
The control system is segmented into two parts: the large touch device that provides full display and functionality, and the remote control that provides condensed access to essential controls. This segmentation allows each component to fulfill its optimal function without compromising the other.
Solution Approach 2:
The control interface is extended from a two-dimensional screen surface to a three-dimensional system involving both the large touch device and the handheld remote. This adds a spatial dimension, allowing users to interact with the system from a comfortable distance while maintaining full functionality.
3Area of stationary object
If the touch device is mounted on a wall or placed on a table for easy viewing, then the visibility is improved, but the accessibility deteriorates as hands cannot reach the entire screen surface
Solution Approach 1:
The remote control serves as a mediator that bridges the gap between the user's hand and the inaccessible areas of the mounted touch device. By transmitting touch coordinates and control signals wirelessly, the remote enables full accessibility without requiring physical proximity to different parts of the screen.

AI summary
A mobile apparatus configured to communicate with a touch device is disclosed. The mobile apparatus includes a communication interface configured to communicate with a touch device; an interface configured to display a user interface window through which an input attribute for a touch that is input at the touch device is selected; and a controller configured to control the communication interface to transmit to touch device information based on the input attribute selected through the user interface window.
