The experience of enchantment in human–computer interaction

Improving user experience is becoming something of a rallying call in human–computer interaction but experience is not a unitary thing. There are varieties of experiences, good and bad, and we need to characterise these varieties if we are to improve user experience. In this paper we argue that enchantment is a useful concept to facilitate closer relationships between people and technology. But enchantment is a complex concept in need of some clarification. So we explore how enchantment has been used in the discussions of technology and examine experiences of film and cell phones to see how enchantment with technology is possible. Based on these cases, we identify the sensibilities that help designers design for enchantment, including the specific sensuousness of a thing, senses of play, paradox and openness, and the potential for transformation. We use these to analyse digital jewellery in order to suggest how it can be made more enchanting. We conclude by relating enchantment to varieties of experience.An earlier version of this paper was presented at Chi’2004 Fringe.

Cyclic voltammetric analysis of antioxidant activity in cane sugars and palm sugars from Southeast Asia

Fourteen commonly available types of cane and palm sugar were analysed for antioxidant activity using cyclic voltammetry. Five of the sugars, dissolved in phosphate buffer, showed anodic current peaks which were indicative of antioxidant activity. The rank order of these sugars was: gula anau > gula merah > China rock honey sugar > soft brown sugar > raw sugar. Gula anau is an unrefined palm sugar, while the other four are from sugarcane. Soft brown sugar and raw sugar are coated brown sugars. The China rock honey sugar contained chrysanthemum flowers, and its antioxidant properties appear to be due to these flowers and not to the sugar per se. Pure white sugar, other rock sugars and rock honey sugars (all refined from cane) as well as gula Melaka, an unrefined rock sugar from palm trees, had no observable antioxidant activity. It is concluded that, from a nutritional point of view, using gula anau as a sweetener or ingredient in foods or drinks has an added benefit owing to its antioxidant content.
