Two-Handed Controller for Electronic Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional input devices for electronic discovery, such as keyboards and mice, are inefficient and uncomfortable for long periods, limiting reviewers to one-handed operation and providing limited functionality, which slows down the e-discovery process and increases costs.
Innovation Solution
A two-handed controller system that allows for handheld, two-handed manipulation of electronic discovery software, utilizing buttons and joysticks to assign functions, and is ergonomically designed to reduce strain and increase mobility and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional input devices (keyboard and mouse) are used for electronic discovery software, then basic functionality is provided, but reviewer efficiency decreases and operation comfort deteriorates during long periods of use
Solution Approach 1:
The controller is divided into multiple functional zones including a first set of buttons for navigation, a second set of buttons for document review actions, and a joystick for cursor control. Each zone can be independently configured for specific discovery software functions, allowing reviewers to perform multiple tasks without returning to the keyboard or mouse.
Solution Approach 2:
The controller integrates multiple input functions into a single device that can navigate software interfaces, control document viewing, perform redactions, and tag documents. The controller serves as a universal input device that replaces the keyboard and mouse for all discovery software operations, improving both efficiency and comfort.
2Adaptability or versatility
If one-handed operation with conventional input devices is used, then device simplicity is maintained, but functionality is limited and operation speed decreases
Solution Approach 1:
The controller adds a spatial dimension to input operations by incorporating a joystick for continuous cursor control and multiple button zones for different function types. This multi-dimensional input approach allows two-handed operation where each hand can independently control different aspects of the discovery software, significantly expanding functionality beyond one-handed keyboard and mouse operation.
3Ease of operation
If reviewers use keyboard and mouse for extended periods, then basic input requirements are met, but reviewer comfort deteriorates and strain on wrists and hands increases
Solution Approach 1:
The controller enables reviewers to perform all discovery software operations independently without needing to switch between multiple input devices. The integrated design allows reviewers to complete navigation, document review, redaction, and tagging tasks using only the controller, eliminating the need to return to the keyboard or mouse and reducing repetitive strain.
4Productivity
If conventional input devices are used, then device simplicity is maintained, but reviewer engagement in the review process decreases and temptation to navigate away from discovery software increases
Solution Approach 1:
The controller merges navigation controls, document review controls, and annotation controls into a single integrated device. This consolidation keeps reviewers engaged with the discovery software by providing all necessary controls within easy reach, reducing the temptation to switch to other applications or web browsers during the review process.

AI summary
A system for electronic discovery may comprise an electronic discovery platform; a two-handed controller configured to produce a plurality of signals; and a memory configured to store at least one set of controller signal relationships, the controller signal relationships being associated with the two-handed controller. A system for electronic discovery may further comprise an interface application communicatively coupled to the memory, wherein the interface application uses the at least one set of controller signal relationships to associate at least one of the plurality of signals from the two-handed controller with at least one of a plurality of discovery commands associated with the discovery of electronic data, and wherein the interface application communicates a determined discovery command such that the discovery command is executed by the electronic discovery platform.
