Lines may appear jittery or wobbly when drawing slowly with an AES stylus - Acer Community

The system reports the location of the stylus based on the closest grid intersection many times each second. Drawing too slowly may cause diagonal lines to appear wavy because more locations will be reported. This is inherent to all products that use AES technology, and not exclusive to Acer products. We are currently working with stylus manufacturers to help optimize stylus performance on our products.</p> <p>The best way to reduce line jitter is to increase the speed of your strokes. If your lines are not as straight as you would like them to be, we recommend trying the following suggestions: The images below illustrate the difference in the way slow and fast strokes will be reported. The diagonal lines in the images show the lines drawn with the stylus, and each change in color between red and blue shows when a reporting point (green circle) is plotted.</p> <p><br></p><table cellpadding="0" style="border-spacing: 0px; width: 650px;"><tr><td align="center"><b>More reporting points</b></td> <td align="center"><b>2 reporting points</b></td></tr><tr><td><img src="https://us.v-cdn.net/6029997/uploads/migrated/acer_final/67457/aes1.png" alt="image" class="embedImage-img importedEmbed-img"></img></td> <td><img src="https://us.v-cdn.net/6029997/uploads/migrated/acer_final/67457/aes2.png" alt="image" class="embedImage-img importedEmbed-img"></img><br></td></tr></table><p>If your lines are not as straight as you would like them to be, we recommend trying the following suggestions:<br></p> <ol><li>Draw your lines with fast and fluid strokes.</li> <li>Use a line segment tool designed to produce perfectly straight lines.</li> <li>Turn on line smoothing in the software you are using.</li> </ol><meta content="#ConceptD CC314-72G,#ConceptD CN314-72"></meta> </article> </main>
