We studied people's experiences related to four different commercial near-to-eye displays (NEDs). A total of hundred and six participants viewed a 40-min film and completed several sickness-, visual strain- and workload-related questionnaires. The severity of the symptoms varied among the devices used, but on average the sickness experienced and the eyestrain levels remained low. Headset fit affected not only the perceived workload, but also the pleasantness of tasks and NED-related opinion change. The participants were positively surprised at the NEDs' high quality, and many were interested in using wearable displays in the future.
