Holographic Smart glass: The New Era Of Navigation Systems


  • A new module has been announced combining mixed reality with the present smart glass devices.
  • According to Bosch, The Bosch light drive solution will be available to high-volume manufacturers by 2021

Mixed reality (MR) can be defined as merging of real and virtual worlds to produce new environments and visualizations. It is a platform where physical and digital objects co-exist and interact in real-time.

Mixed reality does not exclusively take place in either the physical or virtual world. In general, it encompasses both augmented reality and virtual reality using immersive technologies.

This technology is also considered as a synonym for sixth sense technology. It comprises of a high definition camera, projector and processor unit. Generally, the cost of these components is high. This results in increasing the overall cost of the system. To decrease the overall cost, system on chip design can be implemented in the development of these modules.

Combination of MEMS and mixed reality technology


Bosch Sensortec has unveiled a new module called Bosch light drive. It is a smart glass module that consists of MEMS mirrors, optical elements, sensors, and processor. This design combines the features of MEMS with mixed reality applications.

According to the company, this module uses a micro-electromechanical system (MEMS) based light scanner to scan holographic elements. This scanner is embedded in the lens of smart glass. It helps the projector to produce a crisp image. It also increases the visibility of the projected image in direct sunlight.

In-house development of the Sensor

The company informed that Bosch light drive is compatible with both curved and corrective lenses. The designed system is small and light. This module has a varying dimension of up to 45-75 mm x 5-10 mm x 8 mm. The weight of the final product is of up to 10 grams. This solution is developed in-house by Bosch. The company claims that this SOC design ensures high quality, reliability and performance to the user using the module.
Smart glass module is also equipped with a variety of sensor solutions. The module includes a integrated smart sensor. This one-chip solution combines an accelerometer, gyroscope and a processing unit. The module also integrates with an on-board pressure sensor and a magnetometer. These sensors enable an intuitive user interface. Example for such a feature is the multi-tap function on the sunglass frame.

According to Bosch, Bosch light drive solution will be available to high-volume manufacturers in 2021.

Dr Stefan Finkbeiner, CEO of Bosch Sensortec, commented on the new smart glass light drive system saying ,
“The Smartglasses Light Drive system is the smallest and lightest product on the market today and is, therefore, able to turn almost any regular spectacles into smart glasses. By eliminating distracting phone usage, smart glasses can help improve driving safety and reduce the impulse of users to constantly check their mobile devices for notifications or messages.”

This device can provide a revolutionary change in the field of machine vision systems. It can bring new navigation-based solutions compatible with the currently used devices.
