On my phone i have the iNat App symbol right there on the screen where the thumb lands naturally.
So if i hold the phone and click by accident any symbol with my thumb it will be iNat any way.
I like to use the iNat App because there i have every thing that i need to make a good observation.
There is in any case the option to do some instant notes, it makes automatically the GPS thing or it lets me use the map (even offline!), some times i also can instantly ID the observation directly while i am offline (if i know the taxon).
Some times i also do observations like a mushroom and then may also the tree where the mushroom is growing as a separate observation as it is an other life-form, or a bee but then also the plant, and then such observations in the gallery of the phone will look very similar or may look even like one single observation, for sure in the phone gallery it is very unordered and very confusing (to not say āits a messā), in the iNat app every thing is very well sorted and in order.
The problem i also have when using a cam (not a phone), i then stimm need the phone for the GPS and date stuff, then i need to do the observation with the phone first, and then when there is time i can do good pictures with the cam, but to keep order i need also a picture in the phone and the cam as as marker to mark where the observation as a series of pictures stars or ends, and then later i have to delete the marker from the observation and replace it with the additional pictures from the cam (you may can imagine, just to use the iNat solution is the way more simpler way).
Honestly i dont want to open a new box, but if you ask me, some one even should hack the OS of some cams like Nikon in my case, to make them run iNat by default (sadly my cam has no GPS or keyboard).
There is no rule at all, beside the iNat rules on observations like to add a location and a date and some evidence like a picture or some sounds, and not even that is a fix rule as you can do also observations with no evidence or no date or no location.
But in some cases it is very helpful to do a observation with just one hand on the cam, because then you have the other hand free to hold a gras still while it is windy or to slightly turn the stem of a plant so that you can see the bug better or also from an other side (such details can be important in some cases and makes an observation for sure more useful to people who not just want to take pictures but also want to learn).
You may misinterpret what i am asking for. it does not have to be a boolean AND solution, it could be and would be better an boolean OR solution. Just a button in the Settings to switch the knobs to the oder side. In some floating GUI this may means some thing like āif switch button is true then stitch the buttons 1 to X to the other sideā.
At the very end the buttons could even be on the bottom side of my shoes, if it is just a solution that allows users to act quickly without may even harming them self (and buttons on the lower side of the shoes is not realistic and even less handy at all, but the example should show you, that i am open to any good solution for all users including left handed users).
What wonders me a bit, by the way, iNat is used by so many scientists or students, may most are in the field of biology and not medicineā¦ and no one has asked for lefthand mode?!
Its well known from mobile phone users who use theyr phones often to message theyr teenage friends, that they (when very addicted to social media) they get even rheumatic problems in theyr fingers in early age, because they move theyr fingers a lot but never enough to let the blood flow as it should in theyr fingers.
I think from an ergonomic point of view, in a scientific community like iNat, you dont want your users to use the iNat app for years, to then hear from them that they got an iNat-finger-syndrome.
Ohh, in fact it is not big magic.
You see a bug on a plant, you take the phone, to your hand, its a long bug so you decide to take a landscape picture with the x2 cam, so you get more detail and loose less space in the photo.
Now you let the phone sit on your hand, let it slightly fall forward but hold it with your fingers, so you work some how with statical physic, as the phone is now āsittingā on the palm of your hand right there where your fingers begin, you now have a free thumb. Now you can use the other hand to hold the plant still or to turn it slightly to get a better view on the bug.
Now every thing is in position, you click to take the picture, but the bug did move a bit and you only see his tail, so you turn the plant a bit more, while you still hold the phone in place, and if you hit the repeat button it also goes back to the same settings of can and focus. Now you get your good picture and want to take an other picture to then choose the best, and you get a well picture, then you try to press the OK button, and you want to picture it again to also picture the front view of the bug, then you quickly hit OK button, but you miss it and hit repeat. Now your good picture from the side is gone, the bug runs away, you dont get a front view, and all you have it the tail of some thing and a rheumatic thumb.
At the end, lefthanded people have to live with such stuff, most of the best designers, not only in computer science, never think about lefthanded people.
Even worse, some GUI designers them self are lefthanded and take it as evidence to theyr creativity and they name a bunch of famous lefthanded people what makes them feel better, but then they seem so indoctrinated to a righthanded world, that they even discriminate them self in theyr own GUI designā¦ verry odd (may its just what they have learned in theyr design course, or maybe its because they are not creative enough and just think about all the ānormalā GUIs already out there or because they have to follow some orders from a management that already has a design and only needs a GUI designer to programm it but not to design itā¦ who knows?).
The iNat-App is understood as a field-tool. It is not a outdoor photo-studio. In the field often things have to go quickly, often there is no chance for a ābestā picture. If you are in the field and you picture a dragonfly in the air, there is mostly no second try that is not staged.
Sure you have better chances if you buy a professional photo equipment for just some thousands of bucks, and then you can glue the fly to the air and use your macro-zoom-stuff and take the best photo from every angle you want. Bu the iNat app as a field-tool also wants to reach just normal people, non scientists, wants to connect them to nature, wants to be simple (and all that stuff that you read at each corner in the web and even on the iNat site it self about iNat).
It is an other thing if you, as professional photographer want to do the best picture for your bird-newspaper, or if you are just a curious person that wants to know the name of this odd scary bug in your room to then read on wiki that it does not eat humans.
Sounds like one step forward to a brighter future
