We all know that Google has ended the Google Glass Explorer Program. Many people listed the reasons Google Glass failed, such as too expensive, privacy concerns, etc. Well, the Glass was just a beta product and Google will continue developing Glass. The team is moving out of Google X to become its own division. The head of Glass, Ivy Ross, told the Wall Street Journal they’re already working on the next version of Glass for a consumer release later this year—but only when they believe it’s ready for primetime.

I had worked on a project with Google Glass. It is an app to help new employees to recognize their colleagues and show information such as job title, contact info, org chart, projects, etc. Naturally, it is based on face recognition and the development was pretty smooth. But I also found several shortcomings of Glass. So here is my wish list for Google Glass 2.0.

  • Battery, battery, battery! Google says that the Glass’ battery life is “one day of typical use”. It doesn’t happen to me. My Glass battery often lasts only half day (four to five hours) without intensive use. If I turn on the continuous video shooting, the battery will say bye in less than one hour. Terrible! Even worse, the battery can get very hot easily. Google Glass contains a tiny 570 mAh lithium-polymer battery. It is a reasonable design choice as nobody’s nose and ears want to support a giant battery. Before scientists find materials to build super capacity battery, a possible solution is to employ quick-charging battery that can be charged in minutes rather than hours. Of course, safety is first. No one wants a hot or even exploding battery just behind the ear.
  • More and better ways to control. Wearable devices naturally relays on voice as the input. Of course, Google can do better with the voice recognition. Given the recent advances of deep learning, I am not worried too much on the accuracy of voice recognition in the future. But the voice is not always a good choice to control the device. I always feel odd or even embarrassing talking to a device in the public space. Glass users can control the device with some gestures such as tapping, swiping, and head up. But I wish more and better controls. And it may be beyond simple gestures. For example, why not brain computer interface that creates a direct connection from our brains to our Glass?
  • Better way to see the display. I am not talking about better display such as size, color, or resolution, but just how we see the display. We have to roll our eyes up to see the display. It is really not social friendly when you are facing others. Especially, it is a strong sign of disrespecting others in east Asian culture. If the battery is powerful enough for always-on experience, augmented reality may be a nice solution so that we don’t have to rolls our eyes.

This list can go very long, e.g. stronger CPU, larger RAM, better sound, etc. But the above is most important to me. What’s your wish? Tell us in the comments!
