Designing the nav bar toolbar
I have spent a while working on what the toolbar will look like in the app. The main toolbar is very important as it is the way in which the user navigates the app. “Navigation is a conversation. Because it doesn’t matter how good your site or app is if users can’t find their way around it.” [1] The navigation needs to talk to the user like a conversation. Simple put, easy to understand.
This was my first go at designing a navigation toolbar.
The background was the primary colour of the app. With white coloured icons for the navigation options. Small orange bar let the user know which navigation option was selected.
The reason I decided to go with icons instead of text is for many reasons.
“Icons bring a lot of nice benefits to user interfaces, such as saving screen real estate and enhancing aesthetic appeal” [2]
Icons also “make good targets. They are typically sized large enough to be easily touched in a finger-friendly UI”
I used the orange bar to tell the user which navigation option they had selected. This is because the user needs some sort of feedback with what they are doing. If nothing happened the user might become confused and not now where they are within the app.
I took this idea off from the app Tinder which if you haven’t used it before, has a very intuitive UI.
Although I liked what I had done, It just wasn’t looking “right”.
This was my second try at the toolbar design.
What I did with this toolbar compared to the second was remove the primary colour from behind the icons as it adds more white space.
White space “help maintain focus” it also creates focus point more easily drawing users attention to certain elements. [3]
I also think it looks a lot cleaner with less elements, instead of four colours there are only 3.
I also made the current navigation icon the apps primary colour. This further re-enforces feedback to the user. letting them know where they are within the app.
This is my third and so far final navigation tool bar design.
What I changed from the previous is I -
1. Made the icons smaller
3. Moved the navigation bar to the bottom
The reason I made the icons smaller was to add more white space and make room for the text. But I also followed the material.oi design guidelines and made the icon for a nav bar 24x24 dp. [4] This is the standard and most common guidelines. The reason I have followed these guidelines is because it makes the user instantly more familiar with the app, and further increases trust with the product.
I also added text under the icons. This is because according to Nick Babich [7] there are four different types of icons. Universal icons, Unique Icons, confusing icons and conflicting icons. The search and the mail icon in my toolbar design are examples of universal icons, as they are universally know for what they do and will not get confused with anything else. The leaf by itself is a confusing icon. There is no indication or understanding of what it means with just the icon. Therefore text is needed to tell the user what it is. I then added text to the other universal icons for consistency. [5] [6]
I also moved the nav bar to the bottom. I reason I did this was because whilst doing research I read an article called “ How Do Users Really Hold Mobile Devices?” by Steve Hoober [8]. He found that about half (49%) of people using mobiles use just use one thumb for navigating their mobile. This in turn limits the users dexterity to a certain range. as you can see in the image below.
“Green indicates the area a user can reach easily; yellow, an area that requires a stretch; and red, an area that requires users to shift the way in which they’re holding a device.”
Because of this to make the nav bar more accessible to the user I have moved it to the bottom.
I have been learning a lot about UX over the past weeks, and a lot of simple things I thought would easy and intuitive to design are becoming much more complex under the hood, so to speak..
