Apple has filed for a patent (number 20210255711) for a “deployable mouse key” that hints at an interesting keyboard. Per the patent details, a Mac or (more likely) an iPad keyboard could have a removable key that functions as a mini-mouse.

Background of the patent filing

In the patent filing, Apple notes that the computer mouse has become an essential component of desktop computing since graphical user interface was popularized in the 1980s with the introduction of the Macintosh. In the succeeding years, the computer mouse has undergone a series of innovations including the addition of a right- and left-click button, a scroll wheel, an optical sensor, a track ball sensor, a laser sensor, and wireless communication to the host computer. 

A mouse typically incorporates an ergonomic shape to fit comfortably into the hand, which is one factor that has kept its size relatively stable. Handheld mouse input is also well-suited for many types of precise tasks, such as graphic design, computer-assisted design and modeling, and editing large and complex documents. 

In some cases, portable computing devices such as laptop and tablet computers benefit from using a peripheral mouse input device. However, Apple says that the user is “then burdened with carrying the separate mouse with the computer, and the separate device can be redundant when the computer already has built-in pointing devices.” The company says there’s a “constant need for improvements and innovations to input devices for computer systems.” Apple apparently thinks that a removable mini-mouse key is one such innovation.

Summary of the patent filing

Here’s Apple’s abstract of the patent filing: “A computer input device can include a housing, a set of key switch mechanisms positioned in the housing, and a removable key structure that is operable between a first configuration positioned in the housing and a second configuration detached from the housing. The removable key can have a position sensor, wherein in the first configuration, the removable key structure is operable to provide a key-based typing input, and, in the second configuration, the removable key structure is operable as a computer pointing device using the position sensor. The removable key structure can therefore allow comfortable, portable, and precise pointer input for a computer input system.”
