As the saying goes: "The more the more." Often see some products to publish ads or update the log, most of them have a kind of information: This release adds xx new function. Sounds like a good idea to experience more features. In the early stages of product development or for young products, the increasing functionality is a good thing. But for mature products or established products, just adding functionality will not necessarily bring the user experience up, especially now that the user tastes more and more diao.

There are four sets of attributes in the user experience model of Hassenzahl ' s:

Manipulation, identification, stimulation and evocation.

These attributes can be highly generalized as utility and hedonic properties. The Utility property represents the actual function and use of the product, and the hedonic attribute represents the product's own appearance, temperament or the psychological feeling of the user with a certain detail. Successful products in the sitting with practical properties to meet the needs of users, in the product details of the enjoyment of the attributes are also increasingly important, in the era of intense competition even become the key factor in the user experience.

However, not all teams value hedonic attributes to the user experience of the acceleration, facing more and more PO feature request, very few teams will be in the maintain product basic functions at the same time focus on the development of heterogeneous characteristics, in the individual details convenient to make innovation, The performance of the product's unique temperament and convey the designer and research team to the user's use of subtle care and considerate. Thinking of our own projects, the output of story points appears to be the sole criterion for measuring the performance of research and development departments, before each sprint, and no one care the innovation of feature usability. No one care how to change the current inheritance of several release but has long been no longer the courage of the heroic feature, so, the product research and development into a function of the accumulation, what must have, what is only follow or copy over, away from the outstanding far away.

Hedonic attributes can also be called charm attributes, as a product of the unique temperament, like a beautiful woman's charm, as if to experience, as if the language can not be described clearly. This peculiar experience is caused by many factors:

First of all, it is based on the practical properties of the product. A basic function can not be achieved, the interface ugly obscure, workflow chaos unbearable products, no matter how you do in the special details of how in place, will eventually be the user mercilessly abandoned. Only in many aspects of the product to achieve the industry average level on the basis of the hedonic attribute to stimulate the user's emotional resonance to obtain the possibility of hot holding.

Second, users are not easily aware of hedonic attributes, but as the attribute increases, user satisfaction increases exponentially, much higher than the utility attribute. In the early years, Vaio notebooks were innovative, pleasure, enthusiasm, inspiration, training and Difference 6 design guidelines, to achieve a compact and lightweight fuselage, stylish and exquisite appearance, user-friendly Man-machine interface, colorful color selection and health care, such as multiple hedonic attributes superimposed, creating a Vaio series of glorious course.

Then, after the hedonic attribute reaches a certain number, the early part is gradually degraded into a practical property because of being imitated and studied by other products, so the vitality product needs to increase the hedonic attribute constantly, thus satisfying the user's evolving demand. After the launch of the ipad, the market for tablet computers has been activated, countless manufacturers have followed the investment, a large number of similar products appear. If Apple were to add functionality just to meet the new needs of the user, there would not necessarily be a iPad2 current craze. IPad2 does not add much to the utility attribute, there is no USB, screen resolution or no upgrade, but some of the details made a number of adjustments to the already very thin basis for further "weight loss" in the already very good graphics processing ability to further "upgrade" in the already very cheap price further " Bleed ", resulting in a lightweight powerful cheap and strong experience, directly let other competitors have no way to go.

For hedonic attributes, some design details are always the best show. Product details can spread art, humanism, aesthetic perspective and commercial value. Google has always been very focused on the details of the user's feelings, the most recent one has been an impressive experience is: You can use Google search may forget to switch input method and input the wrong (native language) keywords, Google's search engine will be based on your current location of the local language to determine whether you forget to switch input method, so as to give a warm hint "you are looking for is not (English) XXX?", reduce the error caused by the user's mistake search. What a thoughtful design, how warm the details! Unfortunately, the service does not support Chinese at the moment. The iphone in the input text when the long press will be a magnifying glass, convenient for you to choose the text insertion position, this is a genius detail design, each use, will deepen my appreciation of Apple products. In the Playstation3 of the host power key design, Sony made a fresh attempt, the physical keys replaced by the induction button, with the body temperature of the fingers can be opened, and the pencil, ruler and other objects without temperature can not start when touching. With the tip of the finger lightly brushed, a crisp "drip" sound, PS3 host of the boot music sounded, this has become Sony to bring us wonderful memories.

"The Elders who desire wood must first be fixed to their roots; "Details determine success or failure, in the right direction to dig out the details, every designer should understand and bear in mind." Perhaps, one of the details of your tireless perseverance will eventually open the door of the user's lock.
