Background:　The　sense　of　touch　plays　a　crucial　role　in　interactive　behavior　within　virtual　spaces,　particularly　when　visual　attention　is　absent.　Although　haptic　feedback　has　been　widely　used　to　compensate　for　the　lack　of　visual　cues,　the　use　of　tactile　information　as　a　predictive　feedforward　cue　to　guide　hand　movements　remains　unexplored　and　lacks　theoretical　understanding.　Methods:　This　study　introduces　a　fingertip　aero-haptic　rendering　method　to　investigate　its　effectiveness　in　directing　hand　movements　during　eyes-free　spatial　interactions.　The　wearable　device　incorporates　a　multichannel　micro-airflow　chamber　to　deliver　adjustable　tactile　effects　on　the　fingertips.　Results:　The　first　study　verified　that　tactile　directional　feedforward　cues　significantly　improve　user　capabilities　in　eyes-free　target　acquisition　and　that　users　rely　heavily　on　haptic　indications　rather　than　spatial　memory　to　control　their　hands.　A　subsequent　study　examined　the　impact　of　enriched　tactile　feedforward　cues　on　assisting　users　in　determining　precise　target　positions　during　eyes-free　interactions,　and　assessed　the　required　learning　efforts.　Conclusions:　The　haptic　feedforward　effect　holds　great　practical　promise　in　eyeless　design　for　virtual　reality.　We　aim　to　integrate　cognitive　models　and　tactile　feedforward　cues　in　the　future,　and　apply　richer　tactile　feedforward　information　to　alleviate　users＇　perceptual　deficiencies.　©　2023　Beijing　Zhongke　Journal　Publishing　Co.　Ltd
