In Detail

Touch-screen monitors have become more and more commonplace as their price has steadily dropped over the past decade. Web applications have generally been transferred onto touch-enabled devices by the touch-to- click emulation provided by modern browsers. A relatively new approach to building web applications is to take advantage of touch-enabled devices by harnessing the new events to allow intuitive interactions just like native applications.

Instant Website Touch Integration takes you on an amazing journey through the world of touch events, giving you the necessary knowledge and advice to make sure your web application stands apart from the rest. Different tasks are explained clearly with examples and offer practical advice for implementing the features discussed in your own web applications.

Instant Website Touch Integration takes you from an introduction to touch events to implementing your own custom gestures. The style is fun and engaging, and you will come along for the journey as we kick other established mouse-driven paint applications to the curb by writing our own touch events. This will encompass handling touch events to draw on and erase the canvas as well as giving the user the ability to choose colors via swiping through a preset collection. At the end of your journey, you will know everything you need in order to add touch functionality such as swipes and pinches to your web application.
