Generating the real-time images required for augmented reality (AR) goggles usually requires considerable processing power, so that Raspberry Pi-based DIY work is often difficult to keep up. But what if your AR desires don’t need fancy high-resolution graphics?If the text and occasional icons are enough to complete the work, then These low-fidelity AR goggles come from [bobricius] May be the ideal solution.
Like the self-made AR device we saw before, this device is above all an affordable headset designed to project the display of a smartphone onto a pair of curved optical combiners.But not to put the phone in the earphones [bobricius] Using a customized PCB, it can accommodate a pair of ST7789 1.3-inch 240 x 240 IPS displays. Connected via SPI and supported by almost any microcontroller you want to use, it only takes a few lines of code to transfer some text data in your field of vision.
We have seen augmented reality displays using microcontrollers like ESP32 before, but these are essentially remote displays for more powerful systems. We like this simplified approach, because in many applications, only a few lines of text or some low-resolution images are enough to complete the task at hand. In addition, the commercial headset on which the project is based certainly looks better than some other donated goggles that we have considered modifying in the past.
