In this paper, an autonomous cell injection system based on vision and motion control is proposed for automatic batch injection of suspended biological cells. A plate for accommodating cells is specifically designed to hold and fix the suspended cells. The plate is fixed in a two-axis compliant micropositioning stage to transport cells to pre-planed positions. The cells are located using image-based...
Testing with final users allows evaluators to detect failures and problems that were not considered during the design and the different stages of development of an application or a web site. In order to be able to perform those tests is important to create an environment where user's responses, reactions and opinions while interacting with an application or a web site can be analyzed. A usability...
This paper describes the design and implementation of chess set using electronic circuits and MATLAB software for educational purpose. Nowadays, many children are addicted on the computer games, and tend to neglect the traditional games like chess game. The electronic chess set is designed in order to attract the interest of the children on the chess game. Besides that, the game provides some basic...
In the last two decades the use of technology in art projects has proliferated, as is the case of the interactive projections based on movement used in artistic performances and installations. However, the artists responsible for creating this work typically have to rely on computer experts to implement this type of interactive systems. The tool herein presented, MotionDesigner, intends to assist...

The work explores the integration of the Internet of Things, such as multimedia, wireless Internet communication, and automation control techniques into a powered wheelchair system. In particular, multiple...
The aim of this paper the extraction of human body dimensions using the latest Microsoft Kinect device. Another focus is the analysis of various application of this device in specific branches of science and research and its application in estimation of dimensions. Brief analysis of the device itself is carried out as well. The principal output of this paper the software application that utilizes...
Due to advancement in minimization and mass-production, cameras are ubiquitously embedded in most of current mobile devices including phones, vehicles, robots, and augmentedreality displays. These mobile cameras are cheap and can gather in real-time large amounts of streaming data about the surrounding environment. Using an information-theoretic model of a streaming video captured by a mobile camera,...
A mobile flying projector is hard to build due to the limited size and payload capability of a micro aerial vehicle. Few flying projector designs have been studied in recent research. However, to date, no practical solution has been presented. We propose a versatile laser projection system enabling in-flight projection with feedforward correction for stabilization of projected images. We present a...
Eye is the main sensing organ in human body, so it contributes much for user interface. Eye tracking has been widely used in Human Computer Interactions. Real time face image capturing along with eye gaze tracking can provide a means of user input to the computer. Here we combine an efficient method for tracking eye and detecting blink to produce an environment by which physically disabled persons...
Closed-circuit television (CCTV) or video surveillance is the most useful technology mostly used in the field of security purposes. CCTVs can be found at many places ranging from public to private places. One of the most challenging problem in installing the CCTV cameras at large scale is storage space occupied by the footage. Footage is mostly stored in secondary storage devices like hard disk drives...
This paper presents the development of an autonomous ball picking robot successfully completed as a one-semester mechatronics senior design project. It aimed to increase the capability of a 6-Axis industrial robot available at school. This project development was performed to demonstrate an autonomous capability of the robot to deal with a dynamic operational environment. The system developed features...
The paper presents a prototype for a two way peer to peer communication and advanced human computer interface (HCI). This could be in the form of a wearable ring equipped with laser, infrared and other radio capabilities that enable the human beings communicate with people and other smart devices in a much natural way. The ring ensembles two way peer to peer laser communication, NFC (Near Field Communication)...
Traffic congestion is a problem that often occurs in the big cities in Indonesia. It is caused by very rapid increase of vehicle. The offered solution is to monitor the traffic situation automatically. We implemented the method of detecting vehicle during night in four single board computers (SBC) that are: Raspberry Pi B+, Beagleboard Xm, Raspberry Pi 2 and Odroid XU4. Perfomance of Odroid XU4 exceed...
In this paper, the design and development of an Unmanned Aerial Vehicle suitable for indoor navigation and an innovative human-computer interaction interface is presented. More specifically, details pertaining to hardware design and software development of the entire UAV are presented. It should be highlighted that the UAV is developed from scratch rather than purchased off the shelf. By virtue of...
On June 5th at 21:10 CEST, the European Space Agency's Telerobotics and Haptics Laboratory conducted the first in history haptic handshake between space and Earth. This demonstration was part of the Haptics-2 experiment, which makes use of two haptic joysticks; one located in space on-board the International Space Station (ISS), and the other one on ground at ESA's laboratory in the Netherlands. Both...
Presented model expands the bi-directional interface for human-computer interaction. It broadens the communication channel from a man towards a computer. This is achieved by using a digital camera devices in the HCI interface and the use of novel (taken from the literature) image analysis. Proposed interface use the full bandwidth video channel, thereby increasing the interface adaptability skills...
This work proposes an accurate marker-less fingertip detection method under single camera. The moving skin regions are analyzed via enhanced mixture models. The models with adaptive learning rates can separate the backgrounds and moving skins effectively. For multiple fingertip detection, we propose an algorithm based on the likelihood computation of contour and curvature information. Furthermore,...
As the rapid development of the Internet of Things (IoT), communication between object, device and machine becomes a popular topic. The application of barcode has become an irreplaceable technique in the field, which provides a new way to embed various information such as hyperlink and text. In this paper, we present a novel voice-based 2D barcode system, which directly embeds voice into a barcode...
The development of intelligent systems to support maritime situation awareness is the main goal of the SEAGULL project. By equipping unmanned aerial vehicles (UAVs) with different types of optical sensors we target an intelligent maritime surveillance system. In this paper we present experiments performed with an hyperspectral camera to detect oil spills. We have developed a detection algorithm that...
Wireless Multimedia Sensor Networks (WMSNs) are composed of the number of video, audio, and scalar sensors which the proposed method is investigated on sensors equipped to cameras. In this paper a new method distributed is introduced for enhancing the environmental multimedia sensing coverage and recording in wireless multimedia sensor networks.
