Engineering Contradiction Analysis
1Device complexity
If monotonic vibration feedback is provided to the user, then the device structure is simple, but the user cannot receive haptic feedback with a sense of presence
Solution Approach 1:
The vibration feedback system is segmented into multiple independent vibration sources (first vibrating device and second vibrating device) positioned at different locations. Each vibration source can be controlled independently to generate different vibration patterns, allowing complex haptic feedback to be constructed from simpler individual vibration elements.
Solution Approach 2:
Different vibration patterns are applied to different locations on the device. The first vibrating device generates vibration in a first direction while the second vibrating device generates vibration in a second direction perpendicular to the first direction, creating location-specific vibration characteristics that enhance the sense of presence.
2Reliability
If vibration feedback based on virtual object attributes is implemented, then the sense of presence is enhanced, but the computational requirements and system complexity increase
Solution Approach 1:
Vibration data is generated in advance based on the attributes of virtual objects (such as mass, material properties) before the actual interaction occurs. This pre-computed vibration data is then retrieved and applied during user interaction, reducing real-time computational requirements while maintaining realistic haptic feedback.
Solution Approach 2:
The system creates a virtual model (copy) of the vibration characteristics based on the attributes of virtual objects. Instead of performing complex physical simulations in real-time, the system uses pre-established vibration data that replicates the expected vibration patterns, reducing computational complexity while preserving realism.
