Over the last several decades, scholars have developed standards for how best to create, organize, present, and preserve digital information for future generations. What has remained neglected for the most part, however, are the needs of people with disabilities. As a result, many of the otherwise most valuable digital resources are useless for people who are deaf or hard of hearing, as well as for people who are blind, have low vision, or have difficulty distinguishing particular colors. While professionals working in educational technology and commercial web design have made significant progress in meeting the needs of such users, some scholars creating digital projects all too often fail to take these needs into account. This situation would be much improved if more projects embraced the idea that we should always keep the largest possible audience in mind as we make design decisions, ensuring that our final product serves the needs of those with disabilities as well as those without.
The needs of people with disabilities have often been overlooked in digital projects, which could be changed by adopting an inclusive design.
41~42. All humans, to an extent, seek activities that cause a degree of pain in order to experience pleasure, whether this is found in spicy food, strong massages, or stepping into a toocold or toohot bath. The key is that it is a ‘safe threat’. The brain perceives the stimulus to be painful but ultimately nonthreatening. Interestingly, this could be similar to the way humor works: a ‘safe threat’ that causes pleasure by playfully violating norms. We feel uncomfortable, but safe. In this context, where survival is clearly not in danger, the desire for pain is actually the desire for a reward, not suffering or punishment. This rewardlike effect comes from the feeling of mastery over the pain. The closer you look at your chillieating habit, the more remarkable it seems. When the active ingredient of chillies — capsaicin — touches the tongue, it stimulates exactly the same receptor that is activated when any of these tissues are burned. Knowing that our body is firing off danger signals, but that we are actually completely safe, produces pleasure. All children start off hating chilli, but many learn to derive pleasure from it through repeated exposure and knowing that they will never experience any real harm. Interestingly, seeking pain for the pain itself appears to be uniquely human. The only way scientists have trained animals to have a preference for chilli or to selfharm is to have the pain always directly associated with a pleasurable reward.
