Blinking UI in Blincam

Blincam  is a cool device. There has been a device which uses the blinking as camera control interface, but it may be first to combine it with a wearable device.

Blinking is a good media to command and control devices, because

  1.  It is a voluntary muscle and perhaps fatigue-less as finger.
  2. People naturally do blinking and it does not require people to learn the operation.

Blincam focuses on a single scenario to capturing a moment – capture what you see. The value proposition is easy to understand. It does not interfere with user sight as traditional camera. This is the same as Google glass.

On the other hand, it is different from Google glass as follows:

  • It is attachable to glasses you use already, not a brand new glasses. Adoption bar is lower than Google glass.
  • Use of Blinking UI
    • It is really hand-free. Google glass used a touch to control the device which is not really hand-free. (People like me thought that Google would combine gaze tracking with its Google glass, but they didn’t…)
    • Blinking keeps privacy of its user better than Google glass. Google glass used a touch/speech to control the device which looks strange in social context. Blinking is less noticeable from the others than speech or touch.

But, as you recognize, Blincam does not solve the problem of privacy of the people around the user. I am not sure about real reasons why Google glass failed, but the privacy of the others may be one of key problems. Blincam must solve the problem to get a broad adoption.

HMD or wearable glasses are another miniature of Desktop

Using Smart-Phone is eye-busy and hand-busy. You can’t use it while doing other things. Using on the road is dangerous.

It is because Smart-Phone is a mere miniature of  desktop computer interactions. Human use hand/finger to input and get information by eye. It doesn’t change human machine interactions fundamentally.

Apple’s Watch is another desktop too. Using it is eye-busy and hand-busy.

Head Mount display or wearable glasses such as Google glass, Microsoft Hololens looks to me yet another miniature of desktop interaction. Using them is eye-busy, though hands may be free. Eye is already busy to catch information from the rich world and to guide reaction against the world. Why do we over-load eye more? Virtual Reality belongs to this eye-busy staff.

I think it is worth pursuing an approach which take information from eye (gaze tracker) without any interference in sight, take advantage of eye to react against world without any interference in sight again.

Google glass

Google glass is a combination of wearable camera/display, touch sensor, and voice recognition.

  • Non-obtrusive capturing of images/movies may attract consumers very much.
  • In addition, their future focus may be to explore argumented reality (integration of atom and bit) and ad business model on it.

It could change the human computer interaction and economy fundamentally. However its focus is not a human computer interaction efficiency nor naturalness, because

  • It uses voice control. Voice interface has limitations about privacy, noise, social strangeness, confidentiality.
  • Touch has a limitation of hand business.

We could provide a bigger impact, the efficacy of computer-human interaction + Google glass values, through overcoming the problems of speech interface and providing the hand-free interface.
