Many products —\u00a0digital and physical — are focused on \u201caverage\u201d users \u2014\u00a0a statistical representation of the user base, which often overlooks or dismisses anything that deviates from that average, or happens to be an edge case. But people are never edge cases<\/strong>, and \u201caverage\u201d users don\u2019t really exist. We must be deliberate and intentional to ensure that our products reflect that.<\/p>\nToday, roughly 10% of people are left-handed<\/strong>. Yet most products — digital and physical — aren\u2019t designed with them in mind. And there is rarely a conversation about how a particular digital experience would work better for their needs. So how would it adapt, and what are the issues we should keep in mind? Well, let\u2019s explore what it means for us.<\/p>\n<\/p>\n <\/p>\n

It\u2019s easy to assume that left-handed people are usually left-handed users. However, that\u2019s not necessarily the case. Because most products are designed with right-handed use<\/strong> in mind, many left-handed people have to use their right hand to navigate the physical world.<\/p>\nFrom very early childhood, left-handed people have to rely on their right hand to use tools and appliances like scissors, openers, fridges, and so on. That\u2019s why left-handed people tend to be ambidextrous<\/strong>, sometimes using different hands for different tasks, and sometimes using different hands for the same tasks interchangeably. However, only 1% of people use both hands equally well<\/a> (ambidextrous).<\/p>\n<\/p>\n <\/p>\n
<\/p>\n
<\/a>\n Challenges for left-handed people<\/a>: when a foldable desk for writing is located on the right. Better: pull it up to the center. (Large preview<\/a>)
\n <\/figcaption><\/figure>\nIn the same way, right-handed people aren\u2019t necessarily right-handed users. It\u2019s common to be using a mobile device in both left and right hands<\/strong>, or both, perhaps with a preference for one. But when it comes to writing, a preference is stronger.<\/p>\nChallenges For Left-Handed Users<\/h2>\n
Because left-handed users are in the minority, there is less demand for left-handed products, and so typically they are more expensive<\/a>, and also more difficult to find. Troubles often emerge with seemingly simple tools \u2014\u00a0scissors, can openers, musical instruments, rulers, microwaves and bank pens.<\/p>\n<\/p>\n <\/p>\n
<\/p>\n
<\/a>\n Challenges for left-handed people<\/a>: using \u201cregular\u201d scissors with the left hand can be difficult for left-handed users. (Large preview<\/a>)
\n <\/figcaption><\/figure>\nFor example, most scissors<\/strong> are designed with the top blade positioned for right-handed use, which makes cutting difficult and less precise. And in microwaves<\/strong>, buttons and interfaces are nearly always on the right, making left-handed use more difficult.<\/p>\nNow, with digital products<\/strong>, most left-handed people tend to adapt to right-handed tools, which they use daily. Unsurprisingly, many use their right hand to navigate the mouse. However, it\u2019s often quite different on mobile<\/strong> where the left hand is often preferred.<\/p>\n\n- Don\u2019t make design decisions based on left\/right-handedness.<\/li>\n
- Allow customizations based on the user\u2019s personal preferences.<\/li>\n
- Allow users to re-order columns (incl. the Actions column).<\/li>\n
- In forms, place action buttons next to the last user\u2019s interaction.<\/li>\n
- Keyboard accessibility helps everyone move faster (Esc<\/kbd>).<\/li>\n<\/ul>\n
Usability Guidelines To Support Both Hands<\/h2>\n
As Ruben Babu writes<\/a>, we shouldn\u2019t design a fire extinguisher that can\u2019t be used by both hands<\/strong>. Think pull up and pull down, rather than swipe left or right. Minimize the distance to travel with the mouse. And when in doubt, align to the center<\/strong>.<\/p>\n\n- Bottom left \u2192 better for lefties, bottom right \u2192 for righties.<\/li>\n
- With magnifiers, users can\u2019t spot right-aligned buttons.<\/li>\n
- On desktop, align buttons to the left\/middle, not right.<\/li>\n
- On mobile, most people switch both hands when tapping.<\/li>\n
- Key actions \u2192 put in middle half to two-thirds of the screen.<\/li>\n<\/ul>\n
<\/p>\n <\/p>\n

<\/a>\n Opposite-Handed UX test<\/a> can be helpful to test how good the UI is — also known as \u201cleft-handed oil test\u201d for physical products. (Large preview<\/a>)
\n <\/figcaption><\/figure>\nA simple way to test the mobile UI is by trying to use the opposite-handed UX test<\/strong>. For key flows, we try to complete them with your non-dominant hand<\/strong> and use the opposite hand to discover UX shortcomings.<\/p>\nFor physical products, you might try the oil test<\/strong>. It might be more effective than you might think<\/a>.<\/p>\nGood UX Works For Both<\/h2>\n
Our aim isn\u2019t to degrade the UX of right-handed users by meeting the needs of left-handed users. The aim is to create an accessible experience for everyone<\/strong>. Providing a better experience for left-handed people also benefits right-handed people who have a temporary arm disability.<\/p>\nAnd that\u2019s an often-repeated but also often-overlooked universal principle of usability<\/strong>: better accessibility is better for everyone, even if it might feel that it doesn\u2019t benefit you directly at the moment.<\/p>\nUseful Resources<\/h2>\n\n- \u201cDiscover Hidden UX Flaws With the Opposite-Handed UX Test<\/a>,\u201d by Jeff Huang<\/li>\n
