"mvis is arguing that some things are not easy or possible to do with just voice, so touch/interactive control is desirable, and mvis is surely arguing that interactive projection (combined with voice) is the best approach?
Yep... they've been arguing about a lot of things they're trying to sell..... The people I know use Alexa while they're doing other things... away from Alexa....and control what they want ALEXA to do with their voice. The use their laptops for more sophisticated challenges.... I'm not sure people need touch interaction with Alexa instead of voice...or even added... Like many features of VHS recorders that people didn't use.... VOICE and looking at the DISPLAY seems to be what I've seen used...while they're doing something else... like eating...
