Smartphone Mediator for MFP Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visually impaired users face difficulties in operating and controlling multifunction peripherals (MFPs) due to the reliance on touchscreen interfaces, which are not accessible for them.
Innovation Solution
The use of Bluetooth Low Energy (BLE) beacons and smartphones or tablets with audio interfaces allows visually impaired users to interact with MFPs through audio menus and status updates, enabling them to control MFPs without hardware modifications, using existing devices and technologies like Android and iOS devices, and fallback solutions like Wi-Fi broadcasting for in-browser assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touchscreen interface is used for MFP control, then device functionality is comprehensive, but accessibility for visually impaired users deteriorates
Solution Approach 1:
The patent introduces a smartphone or tablet device as an intermediary between the visually impaired user and the MFP. The intermediary device provides audio output capabilities that the MFP lacks, while the MFP provides document processing functions. This mediator enables visually impaired users to access MFP functions through audio feedback and speech recognition, resolving the accessibility issue without compromising the MFP's comprehensive functionality
Solution Approach 2:
The patent makes the MFP accessible to multiple types of users by integrating speech recognition and audio output capabilities. The system can serve both visually impaired users through audio interfaces and sighted users through the traditional touchscreen interface, thereby achieving multi-functionality and universal accessibility across different user needs
2Ease of operation
If audio interface is added to MFP, then accessibility for visually impaired users is improved, but device complexity increases
Solution Approach 1:
Instead of adding audio interface hardware directly to the MFP, the patent uses the smartphone or tablet as a mediator that provides audio capabilities. This approach improves accessibility for visually impaired users without increasing the complexity of the MFP itself, as the audio processing is handled by the intermediary device
Solution Approach 2:
The patent replaces the need for physical audio interface hardware in the MFP with software-based speech recognition and audio output through the intermediary device. This substitution eliminates the need for additional mechanical or hardware components in the MFP, maintaining simplicity while achieving audio accessibility
3Ease of operation
If speech recognition is implemented, then user interface accessibility is improved, but processing time increases
Solution Approach 1:
The patent implements speech recognition for specific critical functions and commands rather than requiring speech for all operations. This partial implementation provides accessibility benefits for visually impaired users while minimizing the time overhead associated with speech processing, balancing accessibility improvement with efficient operation

AI summary
A system and method for assisted multifunction peripheral user operations employs portable user data devices, such as smartphones or tablets, as an interface for visually impaired users. An application running on the user's device senses when it is proximate to a multifunction peripheral in accordance with a Bluetooth beacon. The user is notified on their device that the nearby multifunction peripheral is configured for audio interaction via the device. When the user accepts the notification, their device is automatically paired with the multifunction peripheral and the user's interactions and instructions can be audio or speech-based via the user's portable device.
