Bosch pushes interactive laser projector to touch on projection screen

On March 15th, Zhizhi Shanghai reported that Bosch launched an interactive laser projection micro scanner, the BML050, in Shanghai today. The device uses a laser as a light source, and can be automatically focused on projections on different distances of the display surface, and can also be projected on a curved surface.

At the same time, the device can also integrate infrared interactive modules, users can touch the screen on the projection screen.
The BLM050 was developed by Bosch Sensortec, a sensor subsidiary of the Bosch Group, and was first released during the MWC2017. This time it was exhibited at the electronic fair in Munich, China. It was the first appearance of the BML050 in Asia. Bai Libo, president of Bosch Sensortec Asia Pacific, said that the touch screen of smart phones creates a very creative way for consumers to interact, but it also limits the way we interact. Because no matter what we do we need to operate on a screen.
"We need a magical way of showing and interacting," said Bai Libo. Based on this consideration, Bosch Sensortec introduced the BML050, which has four major features:

1, using RGB laser as a projection light source. When you project to objects at different distances, you can focus automatically, ie the picture is always clear. In addition, thanks to the laser light source, the BLM050 can also project images onto non-planar objects such as curved surfaces.
2. Touch operation can be performed on the projected screen. By adding an infrared light source to the light source and integrating a sensor that senses reflected light, it can detect which part of the screen the user's finger is touching, thereby allowing the user to complete the touch operation on the projected screen.

3, small size, easy to integrate. The BML050 uses two very small MEMS lenses. The entire volume is very small and can be integrated into tablets, robots and even wearable devices.
4, low energy consumption. According to Bosch, the energy consumption of BML050 MEMS micromirrors is very low. The main energy consumption is mainly generated from laser light sources. Equipment manufacturers can choose different lumens (brightness) laser sources to control energy consumption according to the actual conditions of their products.
Finally, in today's event, Bosch Sensortec CEO Barry Bo also released some views on the smart hardware market.

He said that at present, the most important MEMS market is still concentrated in the field of smart phones, but after the completion of the replacement surge, the growth of smart phones has slowed down, the number of competitors in the MEMS field has also increased, and the MEMS market is shrinking. At the same time, the intelligent wave of robots, wearables, and smart homes is rapidly developing, but it also faces a wide variety of devices and different application scenarios. Therefore, it needs to consume a lot of R&D resources to provide products for them.

"Based on these changes in the market, Bosch Sensortec is transforming itself from a component supplier and package supplier to a solution provider, providing customers with solutions that integrate hardware and software including MEMS, microcontrollers, DSPs, and algorithms." Bai Libo concluded, "Even includes providing application cases to customers."
