U.S. Last month, the Patent and Trademark Office issued a patent for Microsoft titled "Volume Adjustment on Hinge Multi-Screen Device." In 2019, Microsoft has been granted a couple of hinge-related patents for a folded Surface device and two patent applications for hinged devices that are likely to be part of Intel's Project Athena starting to roll out this fall.
The patent covers the elimination of physical buttons for controlling volume on the outside of the device, much like traditional Android and iOS smartphones, and users control the volume by using virtual controls on the screen. This will remove the external finish of the unit.
Microsoft patent FIG. 1 below shows an example of a mobile data processing apparatus; FIG. 2A shows an example of two screens arranged in a side-by-side orientation of the mobile data processing device of FIG. 1
Microsoft's patent, Fig. 3 above, shows a first example of implementation of GUI controls for adjusting audio parameters for mobile data processing device on FIG. 1; FIG. 5 shows a third example of implementation of GUI controls for adjusting audio parameters of the mobile data processing device of FIG. 1.
Microsoft specifically notes that in patent fig. 3 above you are able to see a user interacting with two different applications on multiscreen data processing unit # 12. In this example, a music application (# 40B) appears on the left display device (# 24B), while a game application (# 40A) appears on the right display device (# 24A).
A first graphical user interface (GUI) control (# 27A) and a second GUI control (# 27B) appear on the left display unit (# 24B).
In this case, mentation each GUI control (Nos. 27A and # 27B) is displayed as a slider control on one or both of the display units of a computer program (No. 38 in Fig. 1). .
The invention allows the dual display devices to use virtual display controls to control the volume of music or games instead of physical buttons as most smartphones do to control the volume.
Microsoft patent describes the device which has two face cameras in addition to two depth cameras on the face. The device also has inertial sensors that will turn on the GUI when the user starts unfolding the device to an open position and can support two dual speakers.
Microsoft was granted this patent last month. They originally applied for this patent on June 29, 2017.
