It has been almost a month since the unveiling of the Galaxy S4, and Samsung wants to make sure they still have our attention. Earlier today, they published a presentation on their official blog covering some of the technologies behind the Galaxy S4’s features, and they are really quite impressive.

While previous announcements have been focused mainly on hardware, today’s post focuses on nine sensors, as well as recognition technologies, that understand user behavior.

Sensors and recognition technology

A number of sensors are featured in the GALAXY S4. These sensors are claimed to be smart enough to detect a user’s face, voice, motion, and much more. They include:

  • Temperature / Humidity Sensor – checks temperature and humidity levels
  • Accelerometer – detects the phone movement and is used as a Walking Mate
  • Barometer– identifies the atmospheric pressure at the user’s location
  • RGB Light Sensor (Samsung Adapt Display) – Measures the red, green, blue, and white intensity of the light source.
  • Gesture Sensor– recognizes the user’s hand movements using infrared rays
  • Proximity Sensor – recognizes whether the mobile phone is located near the user by using infrared rays
  • Face Recognition- used for Smart Pause, which pauses a video when the user looks away and resumes when the user returns, and Samsung Smart Scroll, which allows the user to scroll up and down without touching the screen.
  • Finger Hovering- measures electric currents that change when the user’s hand is in close proximity to the touch screen. (First debuted with GALAXY Note 2, this is the first time the technology can be used without an S Pen.)
  • Geomagnetic Sensor (Digital Compass MAP) – detects magnetic field intensity
  • Gyro Sensor (Smart Rotation) – detects the mobile phone rotation

Some of these features are not new, however they have been updated to make things more convenient and hassle-free for the user. According to Samsung, they want to “go beyond simple functions like making phone calls and running applications, so users can focus on themselves and loved ones.

If all of these extra features have you nervous about the battery life, Samsung says not to worry. They say their innovative ideas have also allowed them to optimize the phone’s battery consumption as well:

If all this extra power has you concerned about battery life, fear not. The GALAXY S4 has a Micro Controller Unit (MCU) that activates the Application Processor (AP) only when needed and makes it possible to control the sensors without activating AP. As a result, the power consumption of GALAXY S4 is optimized, letting you enjoy these features longer.
