Metasurfaces, the ultrathin media with extraordinary wavefront modulation ability, have shown versatile potential in manipulating waves. However, existing acoustic metasurfaces are limited by their narrow-band frequency-dependent capability, which severely hinders real-world applications that usually require customized dispersion. To address this bottlenecking challenge, we report ultra-broadband achromatic capable of delivering arbitrary and frequency-independent wave properties bottom-up...

In terms efficiency (speed), is initially slower, but outperforms within 30 minutes practice. Our results potentially a reasonable for general use, particularly exciting use mobile device interfaces.

Low‐frequency broadband locally resonant can be realized patterned with bandgaps are orders magnitude wider than other...

Due to their limited number of units but outstanding ability control rather complex wave-propagation phenomena, acoustic coding metasurfaces (ACMs) as two-dimensional metamaterials show a stronger competitiveness in metamaterial applications. However, hindered by narrow-band modulation capability, the previously reported ACMs do not exhibit broadband applicability. To address frequency-based this paper we report (BACMs) whose are designed bottom-up topology optimization method. Subsequently,...

Unlike their electromagnetic and acoustic counterparts, elastic waves involve different wave modes.

We conducted an empirical investigation of wearable interactive rings on the noticeability four instantaneous notification channels (light, vibration, sound, poke) and a channel with gradually increased temperature (thermal) during five levels physical activity (laying down, sitting, standing, walking, running). Results showed that vibration was most reliable fastest to convey notification, followed by poke sound which shared similar noticeability. The these three not affected level...

Online communities like Dribbble and GraphicBurger allow GUI designers to share their design artwork learn from each other. These sharing platforms are important sources for inspiration, but our survey with suggests additional information needs unmet by existing platforms. First, need see the practical use of certain designs in real applications, rather than just artworks. Second, want not only overall also detailed components. Third, advanced search abilities (e.g., multi-facets search)...

Sometimes users fail to notice a change that just took place on their display. For example, the user may have accidentally deleted an icon or remote collaborator changed settings in control panel. Animated transitions can help, but they force wait for animation complete. This be cumbersome, especially situations where did not need explanation. We propose different approach. Phosphor objects show outcome of transition instantly; at same time explain retrospect. Manipulating phosphor slider,...
