'Good Guy' Google was the first thing that popped into mind when I heard about this. Even if Google is merely trying to stop its revolutionary venture from being tainted by lowly words, it certainly just seems like Google being Google. Funnily enough it goes further than just censoring your words, it just completely ignores anything that's considered swearing.
This trend stated with the Nexus One back in 2010. The built-in voice-to-text feature didn't allow for any expletives whatsoever. Whenever anyone entered in a curse word, it would just type down "####". At the time Google originally said that "We filter potentially offensive or inappropriate results because we want to avoid situations whereby we might misrecognize a spoken query and return profanity when, in fact, the user said something completely innocent".
Obviously Google don't want their products to mistakenly start spewing profanities at their users, but I believe that's not their real intention.
First of all it's Google. When have they not done something because it would be 'too difficult'? People said that it would be incredibly costly and insensible to attempt to project a heads up display (HUD) into glasses, yet Google is prepping to release a set of glasses that has not only has a HUD but replaces your entire phone too. So, I reckon if Google really didn't want their phones to swear at their users, they would just make their software better so that it didn't.
Secondly, it's...well Google, but for a different reason this time. Google are a nice company (by all means comment if you disagree!) as seen by their behaviour with Android. Windows and Apple created their Mobile OSs to be as stringent as possible to prevent competition from using it to create products. Android does the opposite, it was made incredibly open source so that people can do as much as they can do with, generating more opportunities for competitors, because it makes the consumer's life much nicer. (See the original article that talked about this)
So, I reckon Google Glass won't recognize profanities because Google wants us to be better people (what do you guys think?), naturally I'm not certain how effective this might be, but I applaud Google's efforts. Just one more thing about this censoring for those that like to swear. So far there isn't a way of deactivating it.
I open this up to our readers; do you reckon Google are overstepping the boundary here? Or should more companies follow their trend?
