Community Health Workers (CHWs), specially Accredited Social Health Activists (ASHAs) play a significant role in improving healthcare services in developing countries like India. Although ASHAs are key-actors influencing rural health care, they are inefficiently trained. This leads to suboptimal knowledge and skill sets, hence poor information delivery among community members. In this paper, we present the design and evaluation of Pragati, a mobile-based Head Mounted Display (HMD) enabled Virtual Reality (VR) interface for training ASHAs. A user study conducted among 19 users revealed significant learnability and self-efficacy post-Pragati usage. Further, we conducted a between-group study among 57 CHWs to assess effects of 3 platforms (i) Pragati, (ii) mobile phone-based traditional videos and (iii) mobile phone-based 360-degree video on measures of learnability, self-efficacy, engagement, and presence. The results showed no impact of the platform for learnability and self-efficacy, whereas a significant increase in engagement and presence was observed for Pragati. © 2018 Association for Computing Machinery.
