Products that are easy to use are often perceived as pleasurable by users, while conversely products that are difficult to use can lead to frustration or other similar negative emotional responses. Added to the increasing complexity in products and the functions that they fulfil, this can quite easily lead to such responses. Some products can in fact provide a very good function means, but are not appropriately designed to “suggest” or put forward their function and/or operation to the user. This hence brings forward a second DFe guideline that states that in order to stimulate positive emotions; design should include ‘use cues’ into products, i.e. product features that suggest to the user the correct product usage and operation. Such ‘use cues’ are intended to improve the user-product interaction experience especially during the initial moments of interaction that are know as being the most significant for the whole interaction process.

Not just a catchy name, 19 Crimes refers to the number of felonies used to exile convicts from Britain back in 1787, including Jane Castings, who covers the Hard Chard, and John O’reilly, who covers the Red Blend . Upon conviction of at least one of the 19 from that list, prisoners were sentenced to punishment by exile, and were transported to Australia — should they survive the journey there. Those who survived became the first British settlers on the continent.

A British conscript turned infamous convict, Michael Harrington is perhaps best known for orchestrating one of the most daring escapes from Australia. In 1876, Harrington, along with six others, braved a massive typhoon in nothing more than a tiny rowboat to board an American whaling ship in what is now remembered as the "Catalpa Rescue."
