Tags help you find and organize your bookmarks by letting you select all of your bookmarks with a certain tag or combination of tags. Quickly add relevant tags to a bookmark by clicking on any of the recommended tags that appear under the description field on the “Save Bookmark” pop-up. When you are satisfied with the information in the “Save Bookmark” pop-up, click the “Save Bookmark” button. Now a link to the page is stored in your Diigo library, and the information you entered is stored with it.

Highlight Highlighting lets you denote important information on a page, just like highlighting in a book, but with Diigo, the highlighted text will be conveniently saved to your library as well. There are some important things for me to denote on my recipe. My wife doesn’t like pineapple, my grandfather can’t have eggs or chocolate, and I don’t like coconut very much, so I highlight those items on the recipe to let me know I need to deal with them. Highlight by clicking “Highlight” on the Diigolet. Then select the text you want to highlight. The text will be visually highlighted and the text is now stored in your library. It’s that easy. Click the button again to exit highlighter mode. You can also change the color of a highlight by clicking the downward-pointing arrow next to “Highlight” and choosing a color. Colors are useful for differentiating different types of highlights. I will use a different color for each of the different people I need to consider.

To add a sticky note to a highlight, simply move your mouse cursor over a highlight. When the little pop-up tab with the pencil on it appears, move the cursor to it and a menu will appear. Choose “Add Sticky Notes”. Now you can type and post a sticky note just like before, but this time it will be tied to the highlighted text.

Presence is widely accepted as the key concept to be considered in any research involving human interaction with Virtual Reality (VR). Since its original description, the concept of presence has developed over the past decade to be considered by many researchers as the essence of any experience in a virtual environment. The VR generating systems comprise two main parts: a technological component and a psychological experience. The different relevance given to them produced two different but coexisting visions of presence: the rationalist and the psychological/ecological points of view. The rationalist point of view considers a VR system as a collection of specific machines with the necessity of the inclusion of the concept of presence. The researchers agreeing with this approach describe the sense of presence as a function of the experience of a given medium (Media Presence). The main result of this approach is the definition of presence as the perceptual illusion of non-mediation produced by means of the disappearance of the medium from the conscious attention of the subject. At the other extreme, there is the psychological or ecological perspective (Inner Presence). Specifically, this perspective considers presence as a neuropsychological phenomenon, evolved from the interplay of our biological and cultural inheritance, whose goal is the control of the human activity. Given its key role and the rate at which new approaches to understanding and examining presence are appearing, this chapter draws together current research on presence to provide an up to date overview of the most widely accepted approaches to its understanding and measurement.
