Why latency matters
When drawing physical ink on paper, latency is zero. The line appears at the exact molecular point where the pen touches the paper.
In digital systems, the input must be scanned, processed, sent to the OS, interpreted by the app, and finally rendered to the screen. If this process takes longer than roughly 5ms, the human eye perceives the line "dragging" behind the pen tip.
How we fix it
By moving the vector calculations directly onto the pen's ASIC, Interface cuts out the OS processing step entirely, outputting raw coordinate deltas that bypass standard input lag.
