Bezel-less and Edge-to-Edge Smartphone Displays Pose Ergonomic Challenges that Compromise UX, Finds Strategy Analytics

More Physical Effort & Friction is required to Operate Smartphones with Edge Interactions


Boston, MA – January 25, 2018 – Bezel-less and edge-to-edge designs are rapidly becoming the norm, allowing OEMs to squeeze larger displays into a more compact form factor. However, optimizing one-handed usability and adding value through smart implementations of edge interactions is becoming critical. A recent study from the User Experience Strategies (UXS) service at Strategy Analytics “UXS Technology Planning Report: Smartphones”, investigating the needs, behaviors and expectations of consumers regarding smartphones, has found that bezel-less and edge-to-edge designs may enhance the user experience in terms of visual and cognitive aspects, but pose additional ergonomic challenges that can compromise the user’s experience.

Key report findings:

  • The benefits of larger screens through the removal of the bezel or edge to edge displays can obviously be found through displaying more content, legibility of text on the screen, on-screen multitasking and interaction with buttons on the screen.
  • But in turn, more physical effort and friction is required to operate the smartphone. Consumers may experience inadvertent activation of the display, additional extension of the thumb to be able to reach the bottom/top of the screen, having to adjust their grip to reach physical buttons on the device and, additional effort when trying to use the device one-handed when both on and off-screen multitasking.
  • Enabling users to customize how they prefer the virtual home button to work through actions such as ‘always on’ or swiping up, may be a good way to meet the needs for different tasks without compromising usability.

Ji-Wei Wu, Analyst and report author commented, “A reduction in the size of the smartphone bezel is visually striking; it increases the maximum screen size that is possible on a smartphone without necessarily increasing its overall physical size. But devices with edge interactions can result in user frustration when edge features are launched instead of the elements at the edge of an app they actually wanted. One-handed activation is especially problematic due to thumb-heel proximity at the edge of the content area.”

Chris Schreiner, Director of Syndicated Research, UXIP, added, “Device OEMs need to optimize the HMI and utilize machine learning to minimize physical and friction that are caused by these larger displays.”
