## Abstract

Whilst portable electronic devices such as smartphones have become ubiquitous for billions of users their primarily uses are consuming content or generating limited low complexity data. In contrast, laptops, desktop PCs etc. allow users to enter extended and/or complex content due to ergonomic user interfaces such as keyboard and mouse. Moving data requires either a third electronic device, e.g. a USB memory drive, or remotely storing the content. Accordingly, it would be beneficial to provide users with the benefit of entering and generating content on one or more electronic systems supporting ergonomic and user compatible haptic interfaces with the ability to store this upon their PED, e.g. smartphone. It would be further beneficial to provide the user also with a means to enter information into applications upon their PED through such external interfaces rather than the haptic interface of their PED, e.g. typically a small touchscreen.
