Acesso em: 23 jan. 2017.0163-5980http://www.repositorio.ufop.br/handle/123456789/7175Wearable devices have emerged in the last years with new applications that provide user convenience. Healthcare, sports, safety are some examples of applications embedded in thousands of devices released in the last years. Wearable operating systems with different focus emerged together with wearable applications in order to make adjustments and optimizations of software and hardware. This paper presents a wearable operating systems discussion and shows the current challenges and wearable operating system influence. We developed a wearable appliance for geology. The wearable contains a Head Mounted Display (HMD) assembled with Google Cardboard API and sensors connected to developments boards. For each system component was used different operating systems according to hardware and software available. The results indicate some trends for wearable operating systems.en-USabertoWearable Operating SystemArtigo publicado em periodicohttp://dl.acm.org/citation.cfm?id=2903275https://doi.org/10.1145/2903267.2903275
