AB  - Eyewear displays allow users to interact with virtual content displaye
d over real-world vision, in active situations like standing and walki
ng. Pointing techniques for eyewear displays have been proposed, but t
heir social acceptability, efficiency, and situation awareness remain 
to be assessed. Using a novel street-walking simulator, we conducted a
n empirical study of target acquisition while standing and walking und
er different levels of street crowdedness. We evaluated three phone-ba
sed eyewear pointing techniques: indirect touch on a touchscreen, and 
two in-air techniques using relative device rotations around forward a
nd a downward axes. Direct touch on a phone, without eyewear, was used
 as a control condition. Results showed that indirect touch was the mo
st efficient and socially acceptable technique, and that in-air pointi
ng was inefficient when walking. Interestingly, the eyewear displays d
id not improve situation awareness compared to the control condition. 
We discuss implications for eyewear interaction design.
