Chapter 6: User Interfaces for Mobile Media 263 drop the suitable tags on top of the object. Even though the user does not edit the tag’s keyword, the fact that the user has explicitly selected the tag implies importance. Shooting images and videos is one of the most popular tasks for getting content with a mobile device. In a simply form, capturing an image or a video task requires a viewfi nder and zoom, fl ash, and capture controls. Occasionally, the user may wish to override auto- matic settings and, for instance, modify white balance and exposure. Another method to get visual information is scanning, which changes content from a physical to a digital form. It may involve optical char- acter recognition (OCR), where the system identifi es characters from the image and converts them to text. Recording audio is a less frequently used creation method and mainly used for dictation and note taking purposes, and as a secondary modality when shooting video. Writing a document, composing a message, or listing to-do items requires lots of text entry. Furthermore, writing tasks may include embedding other content objects in that text. Text creation implies a need for formatting and styling the text, and supporting formats such as rich text format (RTF). Typically, the operations include changing font faces, sizes and colour, style, and formatting paragraphs (alignment and indentation, for instance). To enhance the presentation, the user may wish to add special characters and symbols. Increased (informal) text-based communication, fi rst via IRC and later via chat, instant messaging, and text messages, has introduced ways to decrease the number of characters that the user needs to type and enriched the communication with new terms, abbreviations, smileys, and emoticons. The older popular terms like BR, IMHO, and 2nite are now have now been added to by dozens of newer expres- sions, such as G2CU (good to see you), ILBL8 (I’ll be late), and 404 (I don’t know), which are challenging for predictive text entry solutions, not least due to their dynamic nature. A smiley is used to express the mood of the writer with ASCII characters. For instance, :-) or :) means happy, :-( is sad. An emoticon is essentially a way to present a smiley in a more graphical and perhaps personal way. Drawing is among other tasks useful in making quick sketches. It benefi ts from a direct pointing device, such as a stylus on a touch sensitive screen, in comparison to an indirect device. Drawing pre- defi ned shapes, such as a line, an ellipse, a rectangle, or a polygon is doable with both input device types, but free-form shapes are diffi cult to draw with a joystick. Furthermore, changing the drawing tool (from pen to eraser, for instance) may be tedious with an indirect pointing device, as it is slower than with a stylus. A drawing can also be seen
