About

" My master thesis is based upon the hypothesis that human body perception and intuition are likely to be influenced by the present form of self-tracking. This trend is highly characterized by quantification, the communication of body data via numbers, lists and diagrams and a gapless documentation. Numbers are objective. Humans are subjective. Latter are therefore highly diverse and cannot be brought down to one common denominator. Undisputed trust into technology has the potential to replace innate intuition. As an interface designer I try to find a ways to challenge this development. I'm excited to introduce two innovative and unique self-tracking devices to you. "

STRESS BALL // The interactive prototype “Stress Ball” determines the stress level by measuring the skin conduction with an external sensor. The value is translated into an physical transformation of a spherical surface – the change oscillates between a smooth and a rough texture. By touching the surface the measurement can be experienced in a haptic way. The transformation is created by miniature nobs, which move out the ball’s surface. The length of the nobs reflects the intensity of the stress level. Through actively touching, pressing or stroking the object, the user quickly starts to sharpen his or her tactile perceptual capacity and to associate different surface conditions with his or her individual stress level. When the colored nobs expand, their movement changes the uni-colored surface into a multicolored sculpture. The effect underlines the emotional accessibility and the three-dimensionality of the product. 580 nobs and the outer shell of the prototype are 3D printed. Every single nob is installed with a compression spring. The effect is realized by a balloon, which pushes the nobs out of Stressball’s skin by inflation.

MUSCLE SHIRT // The wearable concept „muscle shirt“ measures the level of athletic performance by detecting the heartbeat with a sensor integrated into the fabric. If physical activity is measured the fabric contracts. It is gathered on the back of the shirt. By contraction the wearable physically transforms. The transformation ranges between the properties “wide” and “comfortably tight”. It is perceived by the skin surface and has the potential to enhance the adequate posture of the wearer. The transformation can also be associated with psychological values like speed and agility, which are directly related to physical activity during exercise. The transitions of the transformation are fluent and do not include any fixed steps, nor imply any categories. In contrast to existing self-tracking apps, this reproduction of physical activity corresponds with the human body perception and delivers adequate space for innate intuition. In addition to the haptic experience the registered measurements are also communicated in a visual way. The upper layer of the fabric has a finely sliced structure that gets pulled apart through the contraction and reveals an underlying colored layer. The originally monotonous seeming grey fabric transforms into a colorful and lively appearing piece of fashion and second skin. For prototyping the effect was realized with a stepper motor. The motor is connected to the heartbeat sensor and rotates a bar which gathers the fabric at the back of the shirt if athletic performance is measured. In the future, to make ist more "wearable", the effect could be realized with shape memory wires, which are integrated into the fabric. The wires have the ability to contract and relax by minimal, imperceptible electrical power impulses.
