The use of icons to replace words definitely seems to be on the rise. One particular reason is space, always at a premium whether it’s real estate or a web page. Instead of the words “Battery Status” on my kindle, there easily is a battery icon that shows a lightning bolt to show that my battery is charging. Moving the cursor over this icon causes the words “Energy Manager” to pop up in case I didn’t remember the meaning. My car’s dashboard has that picture of an engine complete with a fan that lights up just before my automobile decides to break down on a busy freeway. I am always concerned about civilization because language as well as verbal communications developed to replace cave drawings that our distant ancestors used. I’m concerned that icons are taking us back to those primitive times. Icons even dominate my new smart temperature control device installed on my Heating, Ventilation as well as A/C system. I haven’t figured out how to make it communicate with “Siri”, so I am using manual controls until my nephew figures everything out for me. Until then we actually must learn what those Heating, Ventilation as well as A/C icons mean. I’m relatively sure the plus (+) as well as minus (-) icons are to actually modify the temperature! There is also a snowflake icon that I suppose has something to do with starting the AC appliance as well as not a warning for extremely sensitive college students. The fan icon is self-explanatory as is the little picture of the sunlight that must indicate that my Heating, Ventilation as well as A/C appliance is in heat mode. The teardrop icon is not very clear to me. It may be there to specify the humidity level. It could also serve as a warning that I may shed a few tears over a costly repair bill if I fail to properly maintain my Heating, Ventilation as well as A/C appliance with correct cleaning as well as service by a Heating, Ventilation as well as A/C appliance professional.
