SLR trains recurrent continuous states to represent fingertip and finger direction, then align four later states with pooled target-region visual features before predicting a box. Finger and region annotations supervise training, not inference. On EgoPoint-Ground, Qwen3.5-4B reaches mIoU 0.778 versus 0.750 for same-backbone SFT, a 2.8-point gain, though gains vary by setting.
