With projected capacitive touch technology (PCAP) it has become increasingly common to include a capacitive touchscreen in almost every new product that contains a display. Today many, if not most, users expect a device to be touch enabled and want the user experience to be good. When designing software for touch screen displays, any designer should be aware of some best practices.
Know Your Users
Anytime a new product is created, a key part of the design process is defining the target users of the system. You make assumptions about what country the user will be in, what language they will speak, and even with which hand they will touch the display. Let’s assume for this article that you are designing a product for the US English speaking market. By defining this user group you can now assume that when a user looks at a device their eyes will naturally go to the top left corner of the display. You can also assume that about 90% of users will be right-handed.
Navigation
Users do not want to read a manual or have to “figure out” how to use an application. Navigation elements should be kept as simple and consistent as possible. Luckily there has been a lot of research into designing software for mobile devices that has trained the users what to look for.
