LSVP: Towards Effective On-the-go Video Learning Using Optical Head-Mounted Displays
summary
Presents Layered Serial Visual Presentation (LSVP) that combines sequentiality and data persistence for on-the-go video learning on an Epson BT-300 OHMD versus smartphones. Reports a 56% higher immediate recall when sequentiality and persistence are combined, a 17% boost in 7-day delayed recall on OHMDs, and a 5.6% faster walking speed in hard navigation tasks. Tests use real educational videos across three mobility scenarios (straight path, curved with obstacles, directed navigation) and highlights persistence versus clutter trade-offs.
