It takes our brain some slight extra time to compute that, that's a 2K2 resistor as apposed to the display directly showing 2K2. This would significantly speed things up if the user had intentions of measuring a considerable quantity of resistors.
Another feature might include averaging! The user samples 100 or so resistors and system spits out an average. So if you're going to do an OHM meter project - think different and it might all be worth while. Otherwise, that $5 meter on eBay looks like the go.
Nice out the box idea!!! Like the "2K2" readout.
Here's an even more "out the box" idea:
Somewhere I've got an article saved where an interface to a normal PC screen is shown.
So how about using one of the small screens (like those on cash registers) as the output device.
If it is a color screen, you could also display what the band colors are.
The human brain will probably start to associate the patern (as opposed to the individual bands) with the value and very soon will associate the patern with the value.
Unfortunately, if you then ask them "what are the band colors", they probably wont be able to tell you but if you put a resistor in front of them, they will recognise the color patern and tell you "2K2" or whatever.
This is why people can read but some are terrible at spelling. They recognise the patern of letters in the word and know the meaning but dont ask them what individual letters make up the word.
Best,
