1Speed
If haptic data is transmitted without device-specific adaptation, then transmission speed is improved, but rendering accuracy deteriorates
Solution Approach 1:
The system performs preliminary actions by obtaining haptic device data and determining device capabilities before transmitting haptic data. The haptic engine adapts the haptic data to match the specific rendering capabilities of the target device, ensuring accurate rendering without requiring post-transmission adjustments.
Solution Approach 2:
The system changes parameters by modifying haptic data based on the specific capabilities of the haptic rendering device. Different device types (ERM, LRA, VCM, PZT) have different rendering characteristics, and the haptic engine adjusts the data parameters to optimize rendering accuracy for each device type.
2Manufacturing precision
If haptic device data is obtained and processing is performed to adapt rendering, then rendering accuracy is improved, but system complexity increases
Solution Approach 1:
The haptic engine implements a universal adaptation mechanism that handles multiple device types through a single processing framework. The system maintains a database of device capabilities and uses a unified adaptation algorithm to process haptic data for different device types (ERM, LRA, VCM, PZT), reducing overall system complexity.
Solution Approach 2:
The system introduces an intermediary adaptation layer between the haptic data source and the rendering device. This intermediary component processes the haptic data and transforms it to match device capabilities, simplifying the interface between diverse devices and the haptic engine while maintaining rendering accuracy.
3Manufacturing precision
If haptic device data is obtained and processing is performed to adapt rendering, then rendering quality is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by obtaining haptic device data and determining device capabilities before transmitting haptic data. The haptic engine adapts the haptic data to match the specific rendering capabilities of the target device, ensuring accurate rendering without requiring post-transmission adjustments.
Solution Approach 2:
The system applies partial adaptation by focusing processing efforts on the most critical rendering parameters specific to each device type. Rather than completely reprocessing all haptic data, the system selectively adjusts key parameters that have the greatest impact on rendering quality for the target device.
