Getting Familiar with Microsoft HOLOLENS



Ever since the launch of Microsoft Hololens at inception of 2015, it has continued to amaze the world. The proposed capabilities of cool looking device had left people in awe.

What is Hololens?

It is world’s first holographic head mounted display based on the concept of Augment Reality or rather, Mixed Reality. It lets you interact with holograms within an environment such as your room, providing a truly  immersive experience.

Once you wear the device , your visual world will be over laid by a digital one, without loosing sight of original. The device has high-end sensors and trackers that detect your eye position , capture your hand movements , record and respond to your voice. For starters, you can watch videos , check blogs , open documents. It scans your view and objects and marks them as reference whenever required. You can see a new 3D world in front of you.



According to excerpt from official Microsoft site , Interacting with holograms in mixed reality enables you to visualize and work with your digital content as part of your real world. Realize mixed reality’s promise with Microsoft HoloLens.



Hololens was introduced at Windows 10 launch event earlier in 2015.

  • 2GB RAM
  • 64 GB Flash storage
  • Custom Microsoft Holographic Processing Unit HPU 1.0, Intel 32-bit architecture
  • Multiple environment understanding sensors , ambient light sensor and inertial measurement unit
  • See through holographic lens display with Automatic pupillary distance calibration
  • 2 MP HD camera to capture photos and videos
  • Bluetooth and Wi-Fi connectivity
  • Weighs 579g
  • External speakers, 3.5mm audio jack
  • Charges over micro USB giving 2-3 hour active use battery life

  • Providing Voice support.



  • Gaze helps the device to understand the what to give information about.
