Studying spatial memory and map navigation performance on projector phones with peephole interaction
TLDR
We conducted a study with 56 participants to find out if map navigation and spatial memory performance among users and observers can be improved by using a projector phone with a peephole interface instead of a smartphone with its touchscreen interface. Expand

Revisiting peephole pointing: a study of target acquisition with a handheld projector
TLDR
We present a user study performed with a handheld projector showing that Cao et al.'s model only outperforms Fitts' law in prediction accuracy when different peephole sizes are used and users have no prior knowledge of target location. Expand
