vs. stylus </title><prolog><metadata><keywords/></metadata></prolog><conbody>

<section> <p>Consider the use cases of the application when deciding whether

to use finger or stylus control, or possibly hardware keys. Eliminate the

need to switch from using a finger or stylus on the touch screen, to using

any of the hardware keys. Design should enable completing a task with the

same interaction method as it was started with.</p><note>If your application

is intended to be used with the stylus, rather than a finger, try to present

this clearly to the users from the top level. It can be frustrating to start

using an application with finger touch, then switching to stylus, for example,

if the components on screen suddenly get smaller. </note><p>Decide whether

the application is to be used with a single hand, or two hands. Make sure

users are able to use at least the most important functions with only one

hand, even though the application is designed to be used mainly with two hands.

 With touch screen devices, this means that the users should be able to perform

most basic actions with their thumb.</p> <p>Applications that require the

use of both hands include:</p><ul>

<li><p>Applications that require the use of stylus</p></li>

<li><p>Applications that are intended for landscape mode</p></li>

<li><p>Applications that require data input </p></li>

</ul> </section>
