The iPhone can be synchronized with many devices to make presentations easier but now it can double and triple up as a stylus and laser pointer with the Tangram 'Smart Dot' extension and app.
The device can be attached to the iPhone using the audio jack and the app is free for download. Once the app is downloaded it powers the extension to become a laser pointer. This is perfect for presentations in which the smartphone can be a single prop guiding an entire meeting. The app also lets the iPhone become synchronized with computers so that it can become an on-screen trackpad, making the iPhone a mouse as well. The Smart Dot is perfect for smartphone users both in the classroom and the office.
