From multi-touch to foldable design, there have been a few innovations in the computer mouse segment. But no one had gone so far as to think of a scanner built into the mouse. LG has—with its LSM 100. While it looks like a regular desktop mouse, the LSM 100 is bigger in size, making it a little uncomfortable to hold and use. Although it has the regular controls, including a scroll wheel, a close examination reveals two buttons on the left panel and the sensitive glass casing at the bottom for scanning. To get on with the task, you have to install the Smart Scan software that comes with the mouse. Pressing the scan key launches the software and starts the scanning. By moving the mouse slowly over the document, all text and images can be scanned. While scanning, a real-time scanned image appears on the computer monitor and you can rotate it or adjust colour and brightness using the software. Surprisingly, for its small scanning area, the LSM 100 can be used for scanning A4 and A3 documents .
