It may be the figure of the human handwriting as one of the most interesting outputs. By research on the figure of handwriting, characteristics or behaviors of the human are analyzed and cleared. The purpose of this paper is to report results on the comparison of data (the characteristics data by this measurement method) and the evaluation given by pattern differences of handwriting capital letters: B and D; U and V having constructive similarities. By using the divergence as one of statistics method, figures drawn by the dominant or non-dominant hand of examinees who are selected 40 persons of male and female dexterous students in total. Experiment for data collection is done based on the procedure of the author, and it is done by book-size personal computer display and the mouse device and by the recognition function of the computer. The following results are obtained: 1) average vector on pattern elements of t= (t1, t2, …, t7 or t8) 2) variance and covariance matrix on pattern elements of t = (t1, t2, …, t7 or t8) 3) value of divergence: DBD(t), DUV(t) etc. And, the conclusion of this paper on figures of handwring for male and female dexterous students analyzed by the statistics methods given in chapter 4 are shown.

Human Computer Interaction studies of visual attention in dynamic 3D computer gameplay can be greatly facilitated by automated gaze object logging implemented by integration of eye gaze tracking systems with game engines. This verification study reports the spatial and temporal accuracy of such an integrated system.

Mobility is a big deal for visually impaired people and many of the devices already available on the market suffer for poor degree and form of the information provided to the user. In this paper a new way of codifying the information to the blind end user is suggested.The proposed strategy is aimed to move the focus of the electronic aids from an artificial way to codify the information to a natural form. In particular, the developed contactless haptic cane exploits smart signal processing paradigms and an actuator matrix to produce on the user hand palm a stimulus miming the sensation given by a conventional white cane bumping into a obstacle in the user path.

Chaotic behaviour of nonlinear dynamic system as a mechanism of influence on uncertainty measurement are discussed. Based on the logistic equation as a mathematical model, measeurement uncertainty investigated. In the case when dynamic chaos take place in the system, uncertainty measurement has anormal distribution.

The main purpose of this paper is to present the uncertainty of spectrometric analysis considering peculiarities of chemical measurements. Qualitative evaluation of chemical–physical transformation and impact on uncertainty in spectrometric analysis is presented. Spectrophotometric method is used to show experimentally the influence of analysis conditions on the measurement result.
