A recent patent filing by Google surprisingly indicates that they're seriously eying the desktop and notebook markets for Android. Interestingly, the patent seems to focus on similar capabilities now found in Apple's Multi-Touch Trackpad and Magic Trackpad. In many ways that's understandable considering that Google is working on the Android for x86-project along with a serious list of other Intel-Android related projects. Android is headed for the desktop and today's report lays out Google's specific work on trackpad operations corresponding to touchscreen events.
Patent Overview
According to Google, certain applications and operating systems, such as their own Android operating system, have been designed around a touchscreen user interface. However, it may be beneficial to allow such applications and operating systems to be implemented on more traditional devices, such as a desktop, netbook or laptop device that include physical keyboards and/or pointing devices, such as trackpad devices.
Trackpad operations may be directly mapped to touchscreen events, which may be processed by applications that may be configured to process such events. In such fashion, a computing device may be capable of processing touchscreen-based events for applications that are configured to process such events during execution on the computing device, regardless of whether the computing device includes or is coupled to a touchscreen.
For instance, a user may initially move a single finger on the trackpad device to cause a displayed pointer to move correspondingly on a display device of the computing device. The user may touch or tap a single finger on the trackpad device to deliver a simulated touchscreen finger tap at the current pointer location as displayed on the display device. The trackpad finger tap operation may thereby be mapped to a touchscreen finger tap event that may be generated for processing by an application that is designed to receive input via a touchscreen interface.
Multi-Touch TrackPad
If the user touches two fingers on the trackpad device and substantially moves them together, those movements can be mapped into absolute touchscreen events relative to the current pointer location displayed at the start of movement, allowing the user to directly interact with graphical elements located at the current pointer location as if they are using a touchscreen device, and perform traditional touchscreen operations (e.g., dragging/flinging content, scrolling).
Desktops & Notebooks Configured to Map Trackpad Operations to Corresponding Touchscreen Events
In Google's patent FIG. 1 shown below we see is a block diagram illustrating an example of a computing device (shown as patent point 2 of the patent figure) that may be configured to map trackpad operations to corresponding touchscreen events. The computing device may, in some examples, comprise or be part of a desktop computing device or a mobile portable computing device such as a netbook, laptop or tablet device.
Google states that a user may use multi-touch actions on the trackpad. In the example shown in FIG. 1, the user has placed two fingers of their hand onto the surface of the trackpad device to provide multi-touch input. Of course, the user may provide any form of single- or multi-touch gesture input via trackpad device which includes a stylus option.
Example of Trackpad Operations
Google's patent FIG. 4 shown below is a diagram illustrating example trackpad operations that may be mapped to corresponding touchscreen events.
Virtual Touchscreen Input Device
There may also be a mechanism to map multi-touch operations from the trackpad device to select certain touchscreen events, such as pinch-zoom events. The computing device may, for example, generate such touchscreen events upon determining that the user's two fingers are moving in different directions on the trackpad device, or even possibly by determining that the user is holding down a modifier on the physical keyboard while moving the two fingers on the trackpad device. In such fashion, the track pad can function as a "virtual" touchscreen input device.
Google's patent FIG. 5 shown below is a conceptual diagram illustrating an example mapping of a trackpad tap operation to a touchscreen tap event at a current location of pointer 13. The display device may serve as the output device, such that trackpad 4 and display device 12 in combination may function as a virtual touchscreen device, as shown in FIG. 5.
As one example, Google's patent FIG. 6 shown above is a conceptual diagram illustrating an example mapping of a trackpad multi-touch movement operation to a touchscreen single-touch gesture event.
Google's patent was filed with the USPTO in Q3 2011 and published in February 2012.
Will We See Android on Haswell?
Back in 2005 Steve Jobs announced that Apple was transitioning to Intel's X86 and the transition was rather a quick one due to an army of Intel engineers assisting Apple. So if Intel is now seriously behind getting android to Intel processors, it's all but a done deal. It wouldn't surprise me in the least to see Android on a Haswell based Ultrabook in 2013, as that platform promises to support multiple operating system functionality as you could see in the slide below. Haswell will also power next generation desktops that will support multiple operating systems and voila, Android is a serious candidate for the desktop for Android fans. It's also the processor that will push the Ultrabook to function as a Notebook-Tablet combination unit and there's where Android will be able to shine.
With Apple integrating more iOS features into OS X this summer with the introduction of Mountain Lion, the influences of the tablet market moving into the desktop space will begin to change the traditional desktop OS. The popularity of Android almost demands that it move to something like the Ultrabook so as to function as both a tablet and notebook operating system.
