Website Development With Touch Control Support.
Today, when computer tablets, mobile phones, and other modern gadgets work on touch control, it is important to create sites that would support such control. Otherwise, visitors coming to the site from mobile devices (and there are more and more of them) will be deprived of the opportunity to quickly and conveniently access the necessary information on the site. The creation of sites with touch control support is a competent step towards users of mobile devices.
One of the main tasks of developing sites with support for touch control is to provide visitors to such sites with a correctly responsive interface. So, for example, the size of the target area (target) on the site page is important: too small a target area will be inconvenient to click, and if you make the target area too large, the site page will be wasted.
On average, the width of a human finger is 11 mm; therefore, squares of at least 40 pixels in size are recommended as optimal targets on the pages of the site. Around the target objects, you need to leave a free area with a width of about 10 pixels. At the same time, the capabilities of modern web programming allow you to perform a similar set of distances between objects only for certain users – those who come to the site from touch mobile devices.
Not only the size of targets for clicking on the pages of a site plays a big role in ensuring a high level of usability of sites with support for touch control. It is also important that absolutely all elements of the site interface are accessible for touch control. For example, when using touch control, cursor guidance is not used, which means that if the site design uses drop-down menus that respond to cursor guidance, users of mobile devices with touch control will not be able to use such menus.
Thus, the main design parameters of sites with touch control support include:
size of target objects sufficient for finger pressing;
sufficient distance between the target objects (to avoid accidental erroneous touches);
refusal to use the menu that appears when you hover over;
General Requirements for Mobile Versions.
In addition, when creating sites with support for touch control, the general requirements for mobile versions of sites remain valid: minimizing page size to speed up loading, rejecting an excessive amount of graphics and effects, focusing on simplicity and convenience.
Today it is customary to create several versions of sites at once: one for visitors from ordinary PCs and one for users of mobile devices. When visiting the site, the client application (browser) on the mobile device sends the server containing the site a request containing the name and version of the application, the name of the device’s operating system. Based on these data, the server determines whether the visitor came to the site from a mobile device and, accordingly, issues the version of the site that suits this visitor.
