Google Glass versus the COMPETITION

Details
Google Glass wasn't actually the first smart glasses / smart eyewear device, but Google certainly popularized the concept by focusing on consumer uses combined with a creative marketing campaign. At this month's meetup, we're going to look at Google's competitors. We'll have a presentation and discussion that covers the following:
• What smart eyewear devices are available now?
• What devices are coming later this year?
• How do the features of these devices compare to Google Glass?
• What are the price points? (NOTE: They vary wildly!)
BONUS TOPICS (if time permits):
- Smart contacts: A number of companies are working on contacts technology. This includes display / augmented reality, heat sensors, glucose monitoring and even cameras!
• How far away from shipping products are these devices?
• Will smart contacts replace smart glasses or are there use cases for both?
• How much will the early products cost?
- VR goggles versus smart glasses:
• How are these devices the same?
• How are they different?
• Will both go away if smart contacts technology is realized?
