Mobile desktop convergence is likely to happen sometimes in the next few years, at least for some users, when your smartphone will be the brain of your laptop or desktop computer. So far I imagined the smartphone would fit into a dock powering the phone – potentially wirelessly – and connects it to a large monitor, extra storage, and a keyboard and mouse. But based on a patent filled by Apple, it may also take another form: a laptop dock where your smartphone fits right where the touchpad is supposed to be.
The patent for an “ELECTRONIC ACCESSORY DEVICE” describes “various embodiments of systems and methods for providing internal components for portable computing devices having a thin profile. More particularly, the present application describes an electronic accessory device available to extend and expand usefulness of a portable computing device”.
The patent does not appear to describe the interfaces, but presents the general concept with the laptop dock and smartphone establishing a connection when the phone is inserted into a “port (112) having a size and shape in accordance with host device”. All processing power would be in the host device (smartphone), and the laptop dock would be a dumb device providing the communication interfaces between host and device, a keyboard, a display, speakers, and a battery.
The patent also include a block diagram of the host device, which looks like a typical smartphone to me. The data link (612) between the host and the accessories can be a wired or wireless connection.
