Skaitmeninė pateiktis šiandien yra labiausiai paplitęs būdas mokyti kursų ir rengti mokslo bei verslo pristatymus. Norint paremti šią koncepciją, daugumoje universitetų klasės kambarių ir verslo konferencijų salėse yra įrengtos didelės raiškos projektoriai ir kompiuteriai. Siekiant kontroliuoti pateiktis, dėstytojai ar konferencijos dalyviai turi naudoti kompiuterio klaviatūrą ir pelę. Operacijos, tokios, kaip kitos skaidrės įjungimas, frazės paryškinimas ar grafiko nubraižymas, atliekamos dirbant kompiuteriu užuot tiesiogiai bendraujant su auditorija. Lazeriniai žymekliai – dažnai naudojamas įrankis pateikčių metu. Šis įrankis suteikia didesnę laisvę, tačiau atlikti pateikčių valdymo veiksmams pranešėjas privalo nueiti prie kompiuterio. Panaudojant turimą pateikčių įrangą ir įdiegus vaizdo apdorojimo sistemą, galima pateiktims suteikti interaktyvumo. Interaktyvios sistemos dėka, pranešėjas pateikčių metu galėtų atsiriboti nuo kompiuterio, sutelkti visą dėmesį auditorijai ir tuo pačiu metu atlikti pagrindinius pateikčių valdymo veiksmus. Tokiu būdu pranešėjas pateikiamą medžiagą auditorijai pateiktų efektyviau ir įtaigiau. Atliekant šį magistrinį darbą, sukurta „Fenix“ sistema, kuri internetinės kameros fiksuojamam vaizde, aptinka lazerinį žymeklį, nustato žymeklio padėtį ekrane ir, priklausomai nuo padėties, atlieka pagrindinius pateikčių metu naudojamus veiksmus. / Computer - based presentations are now the most common way to teach courses and make scientific or business presentations. To support this, the majority of university classrooms and corporate conference rooms are equipped with high - definition projectors and computers. To control presentation, teachers or participants of the conference must use the computer keyboard and mouse. Operations such as changing slide, highlighting phrase or graphic, performed by sitting near computer instead of directly communicating with the audience. Laser markers - a tool often used during the presentation. This tool provides more freedom, but presenter must go to the computer to make an action. This document describes a method for interactive presentation controlling using laser pointer, web cam, projector and image processing. In project part you will find the main technical and design issues of system that was developed during master course. Document also contains developed system test results and reviews.

Background: Impaired proprioception has been reported in patients with neck pain. The most common way to assess proprioception is the testing of joint position sense. Researchers usually uses advanced technical equipment. Laser pointer tests have been described for testing global joint position sense against two-dimensional targets, which can also be used clinically. One-dimensional targets can provide accurate information about deviations in the current motion plane and allow easy calculation of a number of additional output variables. Objectives: Evaluate test-retest reliability of a new clinical test using laser pointer and a one-dimensional target for assessment of cervical joint position sense. Design: Cross-sectional test-retest reliability study. Method:The study included 56 individuals, 30 healthy controls and 26 with neck pain were tested at two occasions 6-8 days apart. Calculation of the reliability was done by analysing relative, ICC, and absolute, SEM, reliability. Results: The results were relatively scattered but showed an overall moderatereliability with an ICC between 0,51-0,73, but in some cases a poor reliability under 0,5 except for two measures that showed good reliability over 0,77.The SEM for total group were between 0,72°-2,87°, indicating a relatively high level.  Conclusions: Current research demonstrates an overall moderate reliability testing JPS with a laser pointer and a one-dimensional target.

This master thesis deals with a construction solution for traversing of laser pointer, which is used for position identification for stock removal from the storage unit SSI Logimat, including a construction solution of leading of this traversing. The first part contains a research of storage systems used in logistics, as well as systems upgraded with laser pointer. In main part are described the suggestions of leading of laser pointer traversing, together with the design of mechanical transmission and components associated with mechanical transmission. Subsequently the drive of spin of the laser and drive of mechanical transmission are designed. Selection of drives is verified by calculation. The final part contains the check of leading of traversing by strength calculation for bending, from which is suggested the design of leading reinforcement.
