Boinx Software has released Mouseposé, a mouse pointer-highlighting tool for presentations, screencasts or demos. The software’s being sold at the Mac App Store for $16.99.

Mouseposé dims your screen and shines a spotlight on the area around your mouse pointer. Since mouse clicks get lost during presentations, the software lets audiences visualize each click by drawing a red circle around the pointer for each click. Users can customize clicks to coincide with a specific sound, or give right and left clicks different colors in order to easily tell them apart. When the mouse lingers over a window for an extended period of time, the focus automatically expands to highlight the window.

Mouseposé also sports keystroke visualization tools, so an audience sees each key pressed, for easier comprehension of product demos or training.

“Mouseposé is the perfect tool to grab your audiences’ attention and keep them focused throughout your presentation,” said Oliver Breidenbach, CEO of Boinx. He added that the software is “Our fifth app to hit the Mac App Store, and we are thrilled with the reception we are receiving from customers, and proud to be a part of this new purchase and download platform. We are working hard to make sure that all of our apps are available in the Mac App Store soon.”

One of the busiest booths at last week’s Macworld 2010 Expo was one staffed by a 500-year-old company, showing a sparkling-new product. Papershow makes a presentation interactive over the Web or inside a meeting room. It relies on the magic of Papershow paper, a frame of microscopic points, almost invisible to the naked eye, which work as locators when a special pen moves across the sheet.

The software, pen and paper integrate with JPEG and PowerPoint files, so that slick slide deck you created to dazzle in the boardroom or in a pitch to a client gets a fresh angle. Canson, a French company that started selling paper in the 16th Century, unveiled the product for the Mac at the show, after selling Papershow during 2009 for the PC. It’s a $200 solution that was competing, sort of, with the likes of the massive $4,000 electronic whiteboard in the booth right next door.

The full solution includes a pen with a micro camera, Bluetooth transcorder and a processor on-board; the magic paper both in printable sheets (to put your slides in front of you to annotate) and in a notepad format; and a USB key of 256MB to plug into your Mac and receive the pen’s transmissions. Your presentation’s audience doesn’t even have to be in the room — if you’re able to share your screen over the Web, your marks and notes become part of your show in remote offices.

In front of a crowd still buzzing after a day and a half of expo time, Chason’s rep showed the ability to underline, circle or make a note on top of a PowerPoint slide, in multiple colors. The product makes a presentation more alive than the stock animations from PowerPoint. Once it imports a PowerPoint file for annotation, it can save the resulting markup back to PPT or JPEG formats, or Papershow’s native format.
