User environment location, collection of nearby people, and social situation.Computing environment available processors, devices accessible for user input and display, network capacity, connectivity, and costs of computing.They include the following pieces of the environment: They define context to be the constantly changing execution environment. Schilit et al. claim that the important aspects of context are: where you are, who you are with, and what resources are nearby.As Dey and Abowd published, the ones that can best be exaplained are: There are multiple definitions of context in the field of computing. Doors that opens when a person is near them.A text reader that takes the user proximity to the device to enlarge the text size when the user goes further from it.Here the desirable level could be determinated based on the user’s ableness to hear at some levels. A music player that, when the enviroment’s sounds are too loud, it automatically turns the volume up to a more desirable level.If fact, the are a lot of examples, for instance one can think of: Taken into account the importance of context-aware computing in wearable computers we will investigate the definitions of context, context-aware computing and some others related concepts.įirst of all, let’s review some examples of context-aware applications.

Beginning with an applications perspective on future computing environments, we have been able to identify some of the common mechanisms and architectures that best support context-aware computing. The context-awareness we have promoted considers physical, social, informational and even emotional information. To do this, computational services need to take advantage of the changing context of the user. That future computing environments promise to break the paradigm of desktop computing.

The touchpad is a full custom module made by Synaptics, and is driven by a Synaptics T1320A touchpad controller.Īs we claim in this post, head-mounted displays are probably the most prominent symbol of weareable computers. In their paper, «Context-awareness in wearable and ubiquitous computing», Abowd, Dey, et al. The part’s integrated 9-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data.

It incorporates InvenSense’s MotionFusion (sensor fusion, generated by combining the output from multiple motion sensors). The MPU-9150 is a 9-axis MotionTracking device. Inertial sensor (InvenSense MPU-9150, Gyro + Accelerometer + Compass) This sensor calculates the ambient light to adjust the brightness level of the screen and could also be used to detect if the user’s hands are in front of the glass and activate, for example, gestural commands. Proximity/ambient light sensor (LiteON LTR-506ALS): It is used to detect objects close to the glasses. In this first instance we mention the Google Glass hardware sensors, we ‘ll go deeper in some of the sensors capabilities after we get a bigger picture of the rest of the Google Glass hardware.
