Mobile ITX
« on: December 22, 2007, 11:30:44 PM »
Just read about the mobile ITX form factor that VIA are bringing out. All I can say is, I WANT IT! Check it out:

In particular:

Just imagine a wearable PC built with this platform, maybe using something like this for the display:

And something like these for the input:

Cyberpunk/geek heaven! :-D

I had thought about a wearable Minimig, but that's a little while away.

Anyone else like the whole wearable computer thing, or is it just me?

@cecilia

Those are some great benefits you've mentioned there. My favourite benefit to wearable PCs has to be augmented reality.

Need to know what AR is, see here:

Coolness! :-D

I wonder how much energy it consumes compared to conventional portable devices.


Check out this video (skip to 2:30 for the power consumption bit):

Around 8-10 hours on the device shown, and that has a bigger screen than my solution, along with a regular HD rather than something solid state.

Another way of looking at it is by examining the CPU. The reference design uses VIA's C7-M processor running at 1GHz, which draws under 12 W TDP (Total Design Power). VIA already have other CPUs capable of running at 5W TDP for 1GHz speeds, and this is all at 90nm fabrication. See here:
http://www.via.com.tw/en/products/processors/eden_ulv/
If they moved to a more modern fabrication process the power consumption would be even less.

For comparison, this is the main processor of the iPhone (running at 412Mhz):
http://www.arm.com/products/CPUs/ARM1176.html
As far as I can tell, maximum power consumption of the CPU is 279mW, or 0.279W, which is very impressive. It's rumoured that Apple may change the iPhone to a x86 architecture like Intel's Menlow or Moorestown. Silverthorne (CPU of the Menlow architecture) runs at around 0.55W, which shows you what shrinking production processes (0.45nm) can do.

I believe it would be possible to comfortably run a mobile ITX device off the battery for around a day using current tech, even if it does draw more power than similar tech.

@Speelgoedmannetje
x86 is not the devil. Do you dislike the architecture due to its place in history or for more technical reasons?

Having said that, building a wearable Minimig is my personal dream for the device, here's hoping this becomes a reality.

@Dan
I haven't been following wearable computing closely for 10 years like you, but I do know progress has been slow. The main barriers to more commercial devices (IMO) are:

1. Getting enough computing power in a small form factor (now solved with mobile-ITX).
2. Increasing battery life (bottleneck in many mobile devices, progress very slow but power efficiency making some improvements).
3. Building suitable input and output devices.

Point 3 is most interesting. I liked your ideas about a new UI, never thought of using a wristwatch as small display when HUD not suitable. When using HUD, maybe you could use the wristwatch surface as a touchpad (i.e. mouse replacement)?

For typing, I thought of a solution, though I'm not sure if it would take off. To type, you would wear gloves (wouldn't need any computer hardware in the gloves, but they would need to be of one fixed colour, green let's say). Wearing the HUD, you look down at your hands. The HUD device would have a camera built in, and when it saw the green gloves it would bring up the keyboard interface on screen as a augmented reality object. Typing would work as normal, though sounds would have to be added to give feedback when a key was successfully pressed. When typing was finished, you could look up to take away the virtual keyboard.

I think this keyboard solution would only be suitable for people when they were sitting down. If people tried to type like this whilst walking along it wouldn't be long before the term 'techno-zombie' would be in widespread use!
