Just saw TDK’s latest AR tech at the CEATEC expo today. They showcased retinal projection demos in both 720p and 1080p, along with a teaser for the upcoming 4k technology. The advancements they’re making are intriguing. I’m curious to hear thoughts from others who might have seen the demo. What do you think of the tech, and where do you think this is heading for future applications?
How would an IMU ring on the index finger detect a thumb tap on the middle finger? I can’t seem to figure out how that’d work.
Good question. From what I saw, it might just register the tap without specifically identifying which finger is tapping. It could be more about sensing the interaction rather than pinpointing exact fingers.
That makes sense, but the device still looks a bit bulky to me. Do you think they could have made it more compact?
Yeah, that’s a fair point. I think the focus was on getting the functionality right first, and maybe slimming down the design comes later. But I agree, a more streamlined version would be ideal.
Can you clarify what kind of projection technology they’re using? Is it something like uLED or Lcos?
They’re using laser scanning technology for the projection.
So would that mean they’re likely using a MEMS mirror for the scanning part?
Yeah, that’s probably the case for the 720p and 1080p demos. I’m not too sure what their plan is for the 4k version yet, though.
To be honest, I don’t think many people will want to wear something that looks so bulky.
I get that, but it’s worth remembering this is just a prototype for demonstration purposes. The final product could look a lot different once they’re ready to release it.
