Föderation EN Mi 19.02.2025 16:41:14 @vees Ah. I see your point. That is an angle I didn’t get until now. The way they combine haptics with touch does allow for tactile affordances on a touch screen. I need to mull that over. It’s a really interesting point. |

Föderation EN Mi 19.02.2025 16:43:42 @vees it would be cool if touch screens could create temporary textures. I think haptics are something jiggling behind the screen that I can feel jiggling. Wouldn’t it be neat if the screens were a little flexible somehow and could raise up textures, but also lower them or change them dynamically? You could make physical buttons on the screen that could actually be felt. The dynamism of a touch screen with the physicality of buttons. That would be so cool. |

Föderation EN Mi 19.02.2025 21:04:29 @paco @vees Apple has filed a bunch of patents around reconfigurable surfaces on top of a multitouch sensor going back around 15 years. There are still a lot of problems to overcome. Modern multitouch controllers are basically a specialized camera (like digital x-ray film) with internal image feature recognition. They scan the capacitive sensor grid and determine the capacitance present at each point, then they detect what regions of higher capacitance should be communicated as touch points. The recognition can generally also differentiate between pressures because fingers are squishy. As you press harder, the image of the touch becomes bigger and the edges become sharper. This isn’t really used today, but there’s no fundamental reason it couldn’t be. |
