In order to perform the event of focusing on most mobile phone cameras, you need to press the tiny little shutter button half-way down? Half-way down. That is an example of how much of a surgeon dexterity one needs to interact with some technology pieces.
The funny thing is that technologists (me) are often included into the non-athletic types category. It seems their (mine) muscular structure is not as solid as it should.. I mean, they (I) have no motor coordination whatsover. Don´t get me wrong: when they have to strike on their PS3/Xbox controllers, they are the best. But we are talking dexterity here.
Take a look at this blog post snippet from a photography expert text about the Canon Rebel..
Please note I am not criticizing the blog post above. It´s actually cool.
These buttons measure about 1mm of height (?). The software event of starting the auto-focus process is triggered by pressing these things half-way down, which measures 1/2mm (?)! Now seriously, it is not impossible, I know. But let´s face it, we have a large and comfortable room for improvement here.
Or, we can take Pai Mei´s training and be ready to use such technology:
