Collaborative Art Between Robot and Humans

FRIDA, a robotic arm with a paintbrush taped to it, uses AI to collaborate with humans on works of art. Ask FRIDA to paint a picture, and it gets to work putting brush to canvas. FRIDA, named after Frida Kahlo, stands for Framework and Robotics Initiative for Developing Arts. Users can direct FRIDA by inputting a text description, submitting other works of art to inspire its style, or uploading a photograph and asking it to paint a representation of it. The team is experimenting with other inputs as well, including audio. They played ABBA's ‘Dancing Queen’ and asked FRIDA to paint it.

The robot uses AI models similar to those powering tools like OpenAI's ChatGPT and DALL-E 2, which generate text or an image, respectively, in response to a prompt. FRIDA simulates how it would paint an image with brush strokes and uses machine learning to evaluate its progress as it works. FRIDA's final products are impressionistic and whimsical. The brushstrokes are bold. They lack the precision sought so often in robotic endeavors. If FRIDA makes a mistake, it riffs on it, incorporating the errant splotch of paint into the end result.

Spatial AR Optics by VividQ

The waveguide optics of VividQ and Dispelix display objects with variable depth of field. AR gaming could benefit from a wide field of view. Holographic display developer VividQ and waveguide manufacturer Dispelix report an advance that could improve gaming with transparent AR headsets. A proprietary solution is said to provide a clear image with variable depth of field.

Advantages include a wide field of view and a large eyebox for people with different interpupillary distances (IPD). A critical requirement for a good AR game, according to VividQ, is the ability to accurately render different depths of field. If an insect is crouching at the end of a real corridor, the view should adjust to that distance. If it jumps onto your hand, the focus should shift to a close-up.

XRA Launches Education Working Group

The Washington, DC-based XR Association announced recently it had formed its Education Working Group (EWG) tasked with developing immersive technologies and solutions for academic environments. The EWG will kick off on Thursday, 23 June and will unite professionals across the industry to develop best practices for educators using XR technologies in health and inclusive working. The event comes amid the organisation’s ongoing “Developers Guide: An Industry-Wide Collaboration for Better XR” series, which is set to publish later in the year.

The Washington, DC-based association will also work with the EWG amid its partnership with the International Society for Technology in Education (ISTE) to survey roughly 500 educators and staff about their thoughts on XR technologies in the classroom, the organisation explained in a statement. According to the organisation, all XRA member representatives can join the EWG, and the latter is currently seeking new voices to explore the XR education sector. The news comes just a month after ten tech firms joined XRA to expand the ongoing global ecosystem of immersive companies and their solutions.
