To put it simpy, the BBM Testlab investigates the man-machine-interface of products. Interfaces can, for example, be a switch, a display, a remote control, electrical outputs or the electroacoustic transducer of a device. The sum of visual, auditory and haptic impressions when using a product together with the user’s expectations determines its perceived quality. For example, elderly people have clearly different wishes and needs concerning a telephone than younger people.
Modern consumer electronics like smartphones, for example, have plenty of functions and interfaces, which are only realized or changed by the respective software. However, the hardware features may limit the possibilities of the firmware. We investigate these components separately to define their mutual influence and the potential for improvement. Only knowledge of the individual components allows for an adequate evaluation of the whole product.
