Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motion data is collected from a handheld device to manipulate virtual objects in real-time, then the interactivity and immersion of the system is improved, but the device complexity increases due to the need for sensors, processors, and coordination between multiple devices
Solution Approach 1:
The system divides functionality between separate devices: the handheld device (smart ring) collects motion data using its own sensors, while the wearable device (eyewear) displays virtual objects. This segmentation allows each device to be simpler individually while achieving complex interactive functionality when coordinated through wireless communication.
Solution Approach 2:
A wireless communication interface acts as an intermediary between the handheld device and wearable device, enabling data transfer without requiring direct physical connection or complex integration. This intermediary approach simplifies the overall system architecture by allowing independent device development with standardized communication protocols.
2Speed
If virtual objects are displayed in real-time based on handheld device motion, then the responsiveness and user experience are improved, but the processing requirements and energy consumption increase
Solution Approach 1:
The system processes only the essential motion data needed for virtual object manipulation rather than analyzing all sensor outputs. The handheld device filters and selects relevant motion parameters, reducing the data volume transmitted to and processed by the wearable device, thereby lowering energy consumption while maintaining responsive interaction.
3Measurement precision
If motion data from the handheld device is used to control virtual object position, then the precision of object manipulation is improved, but the difficulty of detecting and measuring motion accurately increases
Solution Approach 1:
The system combines multiple sensor types (accelerometer, gyroscope, magnetometer) within the handheld device to achieve comprehensive and accurate motion tracking. By merging the strengths of different sensors, the system overcomes the limitations of individual sensors and simplifies the overall detection process through integrated signal processing.

AI summary
Systems, devices, media, and methods are presented for using a handheld device such as a ring to manipulate a virtual object being displayed by a wearable device such as eyewear. The path of the virtual object in motion is substantially linked, in time and space, to the course traveled by a hand holding the handheld device. The methods in some implementations include presenting the virtual object on a display at a first location relative to a three-dimensional coordinate system, collecting motion data from an inertial measurement unit on the handheld device, displaying the virtual object at a second location along a path based on the motion data. In some implementations the eyewear includes a projector located and configured to project the display onto a lens assembly.
