In the fourth quarter of 2016, Apple wrote a report entitled "Apple Expands Its Work to Promote Apple Watch to Include Wrist Movements and a Camera." The picture of our cover graphics is taken from the patent application. Apple's patent application published by U.S. Pat. The patent office this week shows that a number of applications were written and are now under a single continuation patent. Nine Apple engineers are listed on this invention, which was filed in March 2019. The 2016 patent application was only listed as a single Apple Engineer.
Apple's Erik de Jong is listed on this patent which makes it a serious project / invention because de Jong is listed as Apple Watch Product Design Lead. His profile shows that he is "Leading a team of design engineers to create next-generation Apple Watch. He later adds, his team is working to" develop future product concepts and features. "
Apple's invention generally applies to Apple Watch to detect a user's motion and gesture input to command commands to the device or to other devices. In particular, Apple Watch can use one or more sensors to determine the user's motion and gesture input based on motion of the user's hand, arm, wrist, and finger.
One or more optical sensors, inertial sensors, mechanical contact sensors, and myoelectric sensors, to name a few examples, can detect movements of the user's body. The device can interpret the gesture as an input command, and the device can perform an operation based on the input command.
By detecting movements of the user's body and associating the mouse elements with input commands, the device can receive user input commands in a different way as well. to, or instead of, speech and touch input, for example
Apple's patent Figs. 9A below illustrates exemplary movements and similar commands; Figs. 9D-9E illustrate example of hand and wrist movement; Figures 9F-9H illustrate examples of finger gestures associated with sign language.
With regard to Patent Fig. 9H, Apple notes that "Detecting sign language may include detection of both finger and wrist movements in both hands by the user For example, a user can sign the word "Go" by extending both index fingers # 903 and # 905 for both hands, bending the remaining fingers # 902 and # 907 for both hands and moving wrists # 920 and # 921 in an alternative and circular fashion.
Apple never explains the other device shown as # 901. It's hard to believe that Apple expects a user to use Two Apple Watches Are there an Apple Watch accessory? For now there is a mystery. Apple's patent Fig. 6 below illustrates a plan view of an Apple Watch with motion and motion detection using inertial sensors; a cross one of a wrist and an Apple Watch with motion and motion detection using mechanical contact sensors; FIG. 7B illustrates a cross section of a wrist and an Apple Watch with motion and motion sensing using optical sensors located in the strap; and FIG. 7C illustrates a close-up of the strap.
Apple's Patent Fig. 8 illustrates a cross-sectional view of a wrist and an Apple Watch with motion and motion sensing using myoelectric sensors.
In some examples, optical sensing may use light sources and light sensors located on the device itself or placed in the Apple Watch band. light sources and light sensors can generate a reflection profile from the reflectance of the light from the user's tendons, skin, muscles and legs. In an example as in Figure 8 above, myoelectric sensors can allow the device to detect the electrical signal or capacitance change in the tendons in combination with the user's motion.
Apple's Patent Fig. 4 below illustrates an exemplary configuration of an Apple Watch on the user's wrist. Specifically, when a user is requested to perform any of the movements illustrated in the figures below, begin with FIG. 3A, fingers # 402, wrist No. 420 and hand no. 404 can move when the user's brain sends electrical signals to stimulate muscles # 430. The muscles then agree in response to received electrical signals.
In response to received electrical signals, tendons (# 410) can be attached to the muscles (# 430), also the contract or movement, and can cause the user's fingers, wrists and hand to move. As tendons contract or move, Apple Watch can detect the movement of tendons, the electrical signal, or both.
Based on either the senate motion or the electrical signal or both, Apple Watch can determine the user's motion and gesture. The movement and gesture can be interpreted as commands to the Apple Watch.
