One day in the not too distant future having a TV that you control with you mind will no longer be science fiction but science fact.  A big Japanese manufacturer has developed brand new technology that measure changes of blood flow within the brain and thus allowing the user to take control away from their fingers.  The technology behind this wizardry is called “Optical Topography”.  Wearing a non-invasive headband that bathes the brain in small amounts of infrared light it then connects to a mapping device via optical cables.  Company “H” say that to control objects by thought power users need to “turn the key and unlock their frontal cortex”. This can be achieved by solving mathematical problems or by singing for example.  Their scientists have already demonstrated the technology using a small train set which test subjects took control of whilst wearing the headband.  Other more advanced uses are being developed including TV remote control emulation.  Whilst this might sound like a great idea cost may be the prohibitive side and the old traditional zapper will be both cheaper and easier.  I can just see some people wearing one of these headbands and struggling to “use the power of their mind” (that’s if they have a mind to use).  Also will the system get confused when you are trying to watch and understand “Eastenders” for instance and change channel or turn the volume up.  I know a few people who struggle with a hand zapper let alone their mind!  What about the best of both worlds – a remote shaped like the old grey matter??
