03-Locating and Sensing

Homework required in preparation for this lecture

  • Read Chapter 8 on Location and Sensing
  • Do some research on the android platform and create a list of all sensors and actuators (e.g. vibration control) available on  android devices
  • Pick an android device you have access to and list all of the sensors/actuators on that device.
  • Write a blog post giving your list of sensors and actuators and mentioning one creative use of each sensor and actuator in your product
  • Write comments on three blog posts of people not in your incubator group.
The goal of this homework is to get you to think about sensors and actuators in the android platform and to reflect on how they might be useful in an application.
