Benefits vs. Drawbacks And what about the apparent lack of consumer demand for In many ways, I think Lutz is right. I wouldn’t hazard a guess self-driving cars? As Apple (rumored to be working on its own at the time frame, but the potential benefits of autonomous self-driving car technology) cofounder Steve Jobs was quoted vehicles are too important to be ignored.

Our job is to figure out • save lives (and eliminate associated medical costs), what they’re going to want before they do.” • reduce fuel consumption (thereby reducing carbon emissions), That’s a big job, but I think you have the tools to do it.

Simulating Reality with a Touch of AR-VR Image Courtesy: Getty Images/ Monkey Business Images Incorporating Haptic Devices into Product Design and Validation For years designers and engineers have worked in 3D modeling and simulation applications with immersive, photorealistic visuals that can mimic reality. The affordable AR-VR gear and hardware that have recently emerged promise to bring the missing piece—a sense of touch—into product development. In this LIVE online roundtable moderated by DE’s Senior Editor Kenneth Wong, industry experts discuss: • bringing CAD data into the AR-VR pipelines; • adopting entertainment and game technologies for product development; • rethinking simulation and validation to incorporate haptic (touch-enabled) technologies.
