Abstract [en]

Keys and locks are designed ubiquitously and seldom chosen as appreciated in a day-to-day life; more often we "just unlock a door to get where we want to be". I challenge that assumption by examining non-functional qualities to make (un)locking an experience rather than a mundane interaction. To do so, a pepper mill, as an everyday object, is analysed using a somaesthetic approach, which acts as a starting point for an autobiographical, crafting-focused design process of key-lock interactions. Two prototypes explored movements and tactile experiences; two functional lock mock-ups combined movement with tactile feeling; and a final lock made of stone was installed in an everyday door. This work found that meaningful experiences can be created with material properties, tactile feedback, key size, lock placement, and playfulness. The results are discussed in terms of design friction and playfulness, both of which lead to meaningfulness and mindfulness. The contributions of this work are (1) a design process of creating meaningfulness by exploring movements, tactility, and materials while producing prototypes for key-lock interaction (2) a proven instance of how a mundane everyday interaction can be transformed into a meaningful experience without disturbing its everyday functionality.

Abstract [sv]

Nycklar och lås är designade allestädes närvarande och sällan valda som uppskattade i vardagen; oftare "låser vi bara upp en dörr för att komma dit vi vill". Jag utmanar detta antagande genom att undersöka icke-funktionella egenskaper för att göra (upp)låsning till en upplevelse snarare än en banal interaktion. För att göra detta analyseras en pepparkvarn, som ett vardagligt föremål, med hjälp av ett somaestetiskt tillvägagångssätt, som fungerar som utgångspunkt för en autobiografisk, hantverksfokuserad designprocess för interaktioner mellan nyckel och lås. Två prototyper utforskade rörelser och taktila upplevelser; två funktionella låsmockuper kombinerade rörelse med taktil känsla; och ett slutligt lås av sten installerades i en vardagsdörr. Det här arbetet visade att meningsfulla upplevelser kan skapas med hjälp av materialegenskaper, taktil feedback, nyckelstorlek, låsplacering och lekfullhet. Resultaten diskuteras i termer av designfriktion och lekfullhet, som båda leder till meningsfullhet och mindfulness. Bidragen från detta arbete är (1) en designprocess för att skapa meningsfullhet genom att utforska rörelser, taktilitet och material medan att producera prototyper för nyckel-lås-interaktion (2) ett bevisat exempel på hur en vardaglig interaktion kan omvandlas till en meningsfull upplevelse utan att störa dess vardagliga funktionalitet.1
