One of the most common devices found worldwide in todays society, is the curtain in

various designs. Different designs which requires different types of physical efforts to be

used and adjusted to achieve the intended purpose.

Due to lack of features in a regular vertical blind and its construction, it makes it hard to

use and apply with normal behaviours of the human. Where the basic idea is based on a

static design with a parallel relationship between the individual vertical blinds is the

prototype based on individual movements of the blinds. A static relationship, which

requires repeated adjustment through the day and the movement of the sun to achieve the

desirable functionality. However, when the user gets interrupted and distracted for example

at work repeatedly during a complete day, his or her performance and creativity at work

will be reduced.

In this paper I have chosen to focus on the interaction design of the vertical blind and how

to improve the interaction relationship between it and the user. Also showing how it is

possible to create solutions for a simple and common unit like a vertical blind, by means of

interactive models, use cases, technical predictions and a proposal of a future GUI that

makes it possible to implement the models in a prototype of an embedded system.
