Finger gesture extraction from an integrated optical touch panel based on mathematical morphology

The paper presents a reliable method of extracting finger 2D gestures on an optical touch panel. All the testing data is captured from an optical AMLCD under the normal office lighting. The experimental results show that the method is efficient to correctly extract one or more-finger gestures from the shadow of finger(s) on the AMLCD. Development of such a method contributes to simplification of hardware requirements for reliable detection technique

Processes of Product Concepting

Chapter 1 contrasts concepting with product design. One of the differences noted was the lack of some of the typical product design characteristics in concepting projects. Concept design activities are not necessarily as closely bound to schedules with defined deliverables, product distribution and sales channels or technical and economic constraints as is product design. The expectations for concepting are higher in terms of the creativity, freedom and obligation to innovate and explore. An ideal process for conceptual design would therefore be to allow talented, well-educated, motivated and hard-working people to explore the design space. However, the present trend is for increasingly collectivity. Concept design is seen as a cross-disciplinary activity involving several professionals, representatives of the users and stakeholders belonging to the broad audience of new technologies. The cooperation, if nothing else, sets pressures on managing, facilitating and controlling the creativity processes. Indeed, conceptual design has become an object of scheduling, method development and even computational support[1].
