The Wearhacks event in Toronto showcased innovative wearable technology applications, including prototypes using Intel Edison, Nod Ring, Muse Headband, and MYO from Thalmic Labs. The event highlighted the potential of P2P replication for seamless data sharing between devices without relying on cloud servers. Couchbase Mobile enables peer-to-peer replication across multiple devices, allowing syncing of content to the cloud or locally. This technology can be used in wearable tech projects, IoT applications, and even mobile apps like Office Radar, which leverages location-based beacons to download content with a simple hand gesture. With Couchbase Lite and Sync Gateway, developers can create offline-online solutions for mobile and embedded devices.
