On-screen annotation

Draft

Introduction

On-screen annotation software allows to annotate screens and its applications and save the result. It can be categorized as a both a kind combination of presentation software, whiteboard, screen capturing and note taking tool. Teachers, for example, also may be interested in tools like Classroom Presenter, e.g. an ink-based collaborative annotation system.

Such software is very useful for teachers who present a mix of software, pictures and other stuff and who don't want to spend time preparing slides vs. preparing cool teaching activities and useful materials....

Features such a system may have are:

• Various drawing tools such as highlight, pen, arrow, rectangle, text box and free hand
• Be able to delete and move objects, undo
• Smooth on/off
• Capture of the whole screen and/or a region (preferably in editable format, but here we are dreaming)
• Works with any software (including applications like CS5 or web browsers)
• Some sort of focus tools (e.g. a spotlight/laster equivalent)
• magnification areas

Software

We found it really difficult to find good enough software and found this quite surprising. After all, one often wants to paint on the screen, both for live presentation and to create annotated screenshots. I didn't find any software that completely satisfy my needs - Daniel K.

General purpose

• Netop pointer (PC/Mac) Seems to be one of the two the best tools I have seen. Price unknown (probably more than $20). The "feature" I really dislike is that I have to select a drawing tool before each gesture. I.e. I can't go on annotating with the same tool without returning to the palette.

• Annotate Pro. Seems to be one of the two the best tools I have seen. See the feature list $20. I find this software more ergonomic than Netop pointer, but I am getting display errors with arrows and other geometric figures, i.e. a white rectangle interleaves with drawings. It will go away after clicking twice on the transparency button. (Win 8 64 bit Nivida laptop)

• Utlimate Pen (Mac) “Ultimate Pen can be used for drawing on just about anything, it is particularly useful when working with presentation software. You may add notes, draw shapes, make comments, or add illustrations directly on the screen.” $ 20.

• ScreenMarker “s a little piece of software that lets you make annotations on your computer screen.” (Warning: difficult to know who is behind this ....)

• Screen Marker (not yet available, march 2011)

Web browser annotation

These tools typically allow for collaborative/share annotation in various ways. And they usually do what you expect them to do, although some people probably will complain that there is no single tool that covers all the needs.
