Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated controllers are used for specific VR/AR systems, then system integration is improved, but developer flexibility and adaptability are reduced
Solution Approach 1:
The controller is divided into two independent parts: a reusable mobile computing device (smartwatch) and a system-specific grip portion. This segmentation allows the computing device to be shared across multiple VR/AR systems while only the grip portion needs to be system-specific, thereby improving developer flexibility without compromising system integration reliability.
Solution Approach 2:
The mobile computing device serves as a universal platform that can communicate with multiple different VR/AR systems through standardized protocols. This multi-functionality enables a single device to adapt to various systems, enhancing developer flexibility while maintaining reliable integration through the grip portion's system-specific design.
2Device complexity
If conventional controllers are used, then device simplicity is maintained, but ability to utilize full range of human abilities is limited
Solution Approach 1:
The mobile computing device functions as a universal controller that can implement multiple input methods (touchscreen, sensors, actuators) to capture a wide range of human abilities. This universal platform maintains operational simplicity while enabling diverse interaction modes including touch, gesture, and physiological sensing.
Solution Approach 2:
The mobile computing device acts as an intermediary between the user's natural abilities and the VR/AR system. It translates various human inputs (touch, gesture, physiological signals) into system-compatible commands, thereby expanding the range of detectable human abilities without complicating the overall interaction model.
3Reliability
If separate power sources are integrated into controllers, then operational independence is improved, but device complexity and power consumption increase
Solution Approach 1:
The power source is merged with the mobile computing device rather than being separate in the grip portion. Since mobile devices already contain batteries and power management systems, this eliminates the need for separate power sources in the grip, reducing overall device complexity while maintaining operational independence through the mobile device's existing power infrastructure.
Solution Approach 2:
The mobile computing device's existing power system serves multiple functions: it powers the grip portion through wireless or wired connection, runs the control software, and manages communication protocols. This multi-functional power management reduces the need for additional dedicated power sources, simplifying the overall system architecture.
4Reliability
If dedicated controllers are designed for specific systems, then system optimization is improved, but ease of manufacture and customization are reduced
Solution Approach 1:
By separating the controller into a universal mobile device and a system-specific grip portion, manufacturing is simplified. The grip portion can be mass-produced for specific systems using optimized designs, while the mobile device is manufactured once and reused. This segmentation improves both system optimization through specialized grips and ease of manufacture through standardized components.
Solution Approach 2:
The system allows for parameter changes in the grip portion's design (shape, size, magnetic properties) to optimize for specific VR/AR systems, while the mobile computing device remains standardized. This enables customization of critical interface parameters without requiring complete redesign of the entire controller, improving both system optimization and manufacturing efficiency.

AI summary
Recent technical advances have expanded the breadth, scope, and affordability of virtual reality (VR) and augmented reality (AR) systems. More people can use VR and AR systems than ever before. However, hand-held physical controls for these systems have not made similar advances yet. For this reason, it remains difficult for developers to create applications that take advantage of the full range of human abilities. In this proposal, we describe a system and method for combining off-the-shelf smartwatches with a set of inexpensive grips or sheaths to control VR/AR systems. With our approach, all of the computation and power for the controller derive from the smartwatch unit, allowing the grips to take almost any form, and allowing developers and designers to integrate a much wider array of interaction styles into their applications.
