Little empirical evidence exists to assist interactive videodisc and computer based training developers in determining optimum user-interfaces. Mouse and keyboard response modes have different instructional, development and cost factor advantages and disadvantages. This paper overviews a presentation related to the author's dissertation experiment covering these issues.

A Comparative Study of Random Patterns for Digital Image CorrelationDigital Image Correlation (DIC) is a computer based image analysis technique utilizing random patterns, which finds applications in experimental mechanics of solids and structures. In this paper a comparative study of three simulated random patterns is done. One of them is generated according to a new algorithm, introduced by the authors. A criterion for quantitative evaluation of random patterns after the calculation of their autocorrelation functions is introduced. The patterns' deformations are simulated numerically and realized experimentally. The displacements are measured by using the DIC method. Tensile tests are performed after printing the generated random patterns on surfaces of standard iron sheet specimens. It is found that the new designed random pattern keeps relatively good quality until reaching 20% deformation.

Straipsnyje pateikiami kelių versijų lietuviškos ir rusiškos sintetinės šnekos suprantamumo ir lietuviškos, rusiškos, vengriškos bei itališkos sintetinių šnekų patrauklumo duomenys. Lietuvių ir rusų diktorių kalba yra suprantamesnė nei atitinkama sintetinė. Ankstesnė rusiškos šnekos sintezė blogesnė nei lietuviška ar patobulinta rusiška sintezė (PRS). Pagal sintetinamų garsų charakteristikas aiškėja dvi priešingos PRS tendencijos - pagal bendrą atpažinimo klaidų mažėjimą ji artėja prie natūralios šnekos, tačiau pagal klaidų homogeniškumą nuo pastarosios tolsta. Kadangi pirmoji tendencija vyrauja, bendra atstojamoji rodo PRS gerėjimą.PRS suprantamumo ir patrauklumo koreliacija taip pat rodo jos didesnį artumą natūraliai šnekai. Tiriamiesiems PRS yra patrauklesnė nei ankstesnė rusiškos sintezės versija. Pastaroji, tiriamųjų nuomone, panašesne į roboto šneką, o PRS - į blogą, tačiau jau žmogaus šnekos versiją.Pagal patrauklumo duomenis natūralią šneką labiausiai vertina vengrų klausytojai, o kritiškiausi jos atžvilgiu yra italai. Visos tirtos sintetinių šnekų versijos vertinamos kaip mažiau patrauklios nei natūrali šneka, tačiau jas patobulinus šis vertinimas švelnėja. EVALUATION OF SYNTHETIC SPEECH QUALITY: A COMPARATIVE STUDY OF SEVERAL COMPUTER-BASED SPEECH SYNTHESIZERS Albinas Bagdonas, Feliksas Laugalys SummaryThis paper examines some versions of Lithuanian and Russian synthetic speech intelligibility and Lithuanian, Russian, Hungarian and Italian synthetic speech acceptability. The speech of both Russian and Lithuanian speaker is more intelligible than Russian or Lithuanian synthesis. Previous version of Russian synthesis is worse than Lithuanian and improved Russian synthesis (IRS). Study of characteristics of IRS sounds shows two opposite tendencies - according to the general quantity of mistake reduction this version is tending towards the natural speech, but according to the homogeneity of mistakes, it moves away. As the first tendency is clearly dominant, the general resultant in the new version shows a tend to improve. Correlation between intelligibility and acceptability of IRS deals possibility of small progress towards the natural speech. The IRS is more acceptable to subjects than previous version. The old synthesis is viewed as a rather decent instance of a robot's speech, while the IRS - as a poor variant of human speech. Acceptability studies showed natural speech more enjoyed by Hungarian listeners and more critical by Italian. All versions of synthetic speech were judged as less acceptable than natural but after improvement most of listeners changed their mind.
