|
13 vs. stylus </title><prolog><metadata><keywords/></metadata></prolog><conbody> |
|
14 <section> <p>Consider the use cases of the application when deciding whether |
|
15 to use finger or stylus control, or possibly hardware keys. Eliminate the |
|
16 need to switch from using a finger or stylus on the touch screen, to using |
|
17 any of the hardware keys. Design should enable completing a task with the |
|
18 same interaction method as it was started with.</p><note>If your application |
|
19 is intended to be used with the stylus, rather than a finger, try to present |
|
20 this clearly to the users from the top level. It can be frustrating to start |
|
21 using an application with finger touch, then switching to stylus, for example, |
|
22 if the components on screen suddenly get smaller. </note><p>Decide whether |
|
23 the application is to be used with a single hand, or two hands. Make sure |
|
24 users are able to use at least the most important functions with only one |
|
25 hand, even though the application is designed to be used mainly with two hands. |
|
26 With touch screen devices, this means that the users should be able to perform |
|
27 most basic actions with their thumb.</p> <p>Applications that require the |
|
28 use of both hands include:</p><ul> |
|
29 <li><p>Applications that require the use of stylus</p></li> |
|
30 <li><p>Applications that are intended for landscape mode</p></li> |
|
31 <li><p>Applications that require data input </p></li> |
