Music Industry Future
[via Om Malik] Umair Haque writes:
Connected music players will totally reshape the future of music distribution. Record stores haven't vanished because, let's face it, shopping for music is fun - part of our utility in consuming media is sampling different goods.
When you combine connected music players with RFID, you get a whole new ecosystem of possbilities for music distribution. Ponder this for a second. RFID opens up whole new kinds of network possibilities for media goods in retail locations. The most obvious is record stores which can beam tracks directly into your iPod without a massive infrastructure investment, while you walk around different listening stations (or similar scenario).
But my money is on clubs becoming music distributors/retailers - when you go to a club, you can get the DJ set or selected tracks beamed into your player. This is a natural evolution for clubs, the most iconic of which (Tresor, Ministry) have evolved naturally into labels with dedicated shops. There are huge synergies here - we go to clubs to hear the tracks DJ's have selected - that's the value they add. But we don't get to consume them later without incurring significant additional cost (ie, tracking down the right tracks on the right CDs at the right record stores). Eliminating this additional cost creates huge gains for consumers.
Intuitive Design
[via Amy Wohl] Jaerd Spoll asks: "What does it mean, from a design standpoint, when someone desires a design to be intuitive?"
In our research, we’ve discovered that there are two conditions where users will tell you an interface seems ‘intuitive’ to them. It only takes meeting one of the two conditions to get the user to tell you the design is intuitive. When neither condition is met, the same user will likely complain that the interface feels “unintuitive”.
Condition #1:
Both the current knowledge point and the target knowledge point are identical. When the user walks up to the design, they know everything they need to operate it and complete their objective.
Condition #2:
The current knowledge point and the target knowledge point are separate, but the user is completely unaware the design is helping them bridge the gap. The user is being trained, but in a way that seems natural.
The biggest challenge in making a design seem intuitive to users is learning where the current and target knowledge points are. What do users already know and what do they need to know? To build intuitive interfaces, answering these two questions is critical.
For identifying the user’s current knowledge, we favor field studies. Watching potential users, in their own environments, working with their normal set of tools, and facing their daily challenges, gives us tremendous insight in what knowledge they will have and where the upper bounds are. Teams receive a wealth of valuable information with every site visit.
For identifying necessary target knowledge for important tasks, usability testing is a favorite technique of ours. When we sit users in front of a design, the knowledge gap becomes instantly visible.
