Web Player: 

Any web browser supporting WebGL like Chrome, Safari, Firefox, and Internet Explorer 11+ should work fine for the Web Player. Among them, Chrome works best on Macs, desktop PCs and Android; Mobile Safari works best on iOS.  And you can use your mobile device with Google Cardboard or any WebVR supporting VR headset to experience VR.
