Touchless Document Processing via Sensor-Triggered Slide Pausing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional document processing devices, such as printers, require physical interaction for setting configurations and executing jobs, which can be a concern in pandemic situations where contact needs to be minimized.
Innovation Solution
A touchless mode for document processing devices is implemented, using a slide presentation on a touch screen panel and detection sensors to allow job execution without physical contact, by detecting paper presence and pausing or resuming the slide sequence based on persistent detection events.

Engineering Contradiction Analysis
1Object-affected harmful factors
If physical interaction with the printer is required for configuration and job execution, then the device can be operated with simple interface, but contact with the printer becomes a vector for spread of contagion
Solution Approach 1:
The patent replaces mechanical/touch-based interaction with sensor-based detection. The detection sensor automatically detects paper presence and triggers job execution, eliminating the need for physical contact with the printer interface while maintaining operational capability.
Solution Approach 2:
The printer system performs self-service by automatically detecting paper presence through the detection sensor and autonomously initiating the printing job without requiring user intervention or physical contact, thereby reducing contagion risk while maintaining ease of operation.
2Object-affected harmful factors
If touchless mode is implemented using detection sensors and slide presentations, then contagion spread risk is reduced, but device complexity increases
Solution Approach 1:
The detection sensor serves multiple functions: it detects paper presence, triggers slide presentation mode, and initiates printing jobs. This multi-functionality reduces the need for separate components and complex control logic, thereby managing device complexity while achieving touchless operation.
Solution Approach 2:
The patent merges the paper detection function with the job initiation function into a single integrated process. The detection sensor's paper presence detection is directly linked to triggering the slide presentation and subsequent printing, consolidating multiple operations into one streamlined mechanism that reduces overall system complexity.

AI summary
Systems and methods relate generally to a document processing device. In an example method thereof, a document processing device is provided having a touch screen panel and configurable for touchless execution of a job. The job is performed with the document processing device with the touchless execution. The touchless execution includes: accessing a slide presentation mode; displaying a sequence of slides on the touch screen panel in the slide presentation mode; detecting paper accessible by a detection sensor of the document processing device; stopping at a slide of the sequence of slides responsive to a detection event of the detection sensor; pausing at the slide responsive to the detection event; and executing the job with the touchless execution responsive to persistence of the detection event by the detection sensor for a set duration during the pause.
