The Promise Of Transparent Circuits 239

Posted by timothy from the heads-up-display dept.
aaron huslage writes "Research into Transparent Circuits has apparently come a long way lately. 'In a development that could accelerate architectural deployment of see-through surfaces with embedded circuitry, researchers from the Tokyo Institute of Technology have greatly improved the processing speed of transparent semiconductors, according to a report in the Nov. 25 issue of the journal Nature.' Imagine that your house is your computer!" Or a truly active windshield display in the car.

      The number of techno-gadgets allowed in an automobile should be inversely proportional to it's mass.
      • there would be an exemption for SUVs.

        just like in the USA, the tax you pay for your vehicle depends on mass. SUVs qualify for "lorry" status, but that would mean inconveniencing SUV users a bit which is the last thing the US wants to do. so they don't make the SUV owners pay accroding to mass like everyone else.

          First off the tax break was initially for Vans and trucks.
          The goal of the break was to allow farmers and small business witht here purches of need equipment. At that time SUV's were nowhere near the weight they are today, and they weren't seen as a status symbol.
          SO the tax break is not now, not has it ever been for 'SUVs'.

          They have since changed that tax break considerably.

      Well this could have some beneficial uses as well such as overlaying dots on where the white and yellow lines are in the road. Especially at night in the rain where the glare of the headlight tend to make the lines hard to see and when you get in a multi lane interchange this can get troublesome. Also if they could change color when you cross them so you know that you could be a bit off course (due to being tired or just been diving for to long) Or overlaying direction from a GPS so you can see where you really should turn. It would be like having an arrow pointing the way. But care should be taken on how much stuff in in front of your field of vision. TV shows, Or cutesy things will just be dangerous.

        I'd settle for one that automatically blocks most of the sunlight. I'm too big for the visors to work without blocking my view of the road, and I almost hit a pedestrian this morning who was wearing white and in the glare of the sun. A dark dot that positions itself between the driver's eyes and the sun would be very useful, even if that's all the 'active' windshield did.

          An active matrix LCD winshield where the "pixels" were half inch square. Just activate the pixels that track through from the sun to my head position. I actually looked into it and without wearing some funny headgear it would be rather tough to actually do.

    • This would be a really lousy way to make a head-up display for a car. The driver would have to shift focus between the road and the windshield display. Current head-up displays use reflection for a reason. When the display is reflected by a piece of glass at a 90 angle it appears as thought the information is being projected in the distance in front of the vehicle, so the driver does not have to shift his focus between far and near to read the information, it looks like it is projected on whatever he is loo
      • You sound like someone who has never driven a vehicle.

        By your logic, cars should not have rearview mirrors, speedmeters, stereos, etc. because these things make you look momentarily away from what's in front of the car.

        Also, Cadillac didn't think that their nightvision system was so bad with their small LCD screen on the dash, in front of the steering wheel.

        (Incidently, for those who don't know, you can now buy the same system and have it installed in your car, with the designed LCD "HUD" or without, so [nightdrivingsystems.com]
        • The nightvision system does not interfere with the view of the road because it is a view of the road. My point was that better technology already exists for a HUD. The whole point of a HUD is so the driver does not have to look away from the road. If you are going to put in an LCD panel, it might as well be on the dashboard, because the driver still has to look away from the road.
