Mobile-computing vendor Livescribe has released a smartpen that can work on small devices such as tablets and smartphones. The Livescribe 3 smartpen uses a mobile machine’s microphone to record directly on the device. It also has a capacitive stylus, which can be used to write on the smartphone or tablet, opposite the ink pen tip. The smartpen has a mobile app that can record and playback audio, organize data, and add photos to notes, which users could share via e-mail or save to applications such as Evernote and Dropbox.
