Transla-Pen

The Transla-Pen (トランスペン) is a language translation tool, sold in Academy City.

Principles
As its name suggests, the pen-shaped device is a tool that translates written text and spoken words between languages. A user can use the tool to translate between two set languages (such as English and Japanese) by either tracing the tip of the pen over written text or by using the microphone in the tip to pick up spoken words. The accessory can be synced with a phone, but is capable of audibly translating a conversation back and forth between two people without doing so. It is quite cheap, sold at discount stores in Academy City and coming as a free bonus with language material bought online, however its performance isn't always up to par.

Los Angeles Arc
{{Expand {{Expand|GT4 - Full referencing}} At some point prior to December 26th, Kamijou Touma had bought a Transla-Pen, thinking that he might need it sometime, but it had ended up unused and gathering dust. Early in the morning on December 26th, after escaping hospital he had Fukiyose Seiri and Himegami Aisa bring him some of his things, particularly his Transla-Pen, before being picked up by the Anglicans. He made extensive use of the accessory during the subsequent events in Los Angeles, though he was annoyed at the device's poor performance at times.
