Students at the Technion have developed a system that informs the user whether the Faculty prayer room is occupied or vacant and whether the worshipers are men or women. It does this with the aid of sensors alone, and without using a camera, which could violate the worshippers\u2019 privacy<\/b><\/p>\n
Mosallah (\u0645\u0635\u0644\u0649<\/strong>) is the name of an original system for monitoring the presence of worshippers in the Muslim prayer room at the Technion Faculty of Computer Science. The unique app can identify the current stage of the prayer and, according to this information, the system can estimate when the prayer will end. The innovative system was developed by three students at the Technion Faculty of Computer Science – female students Anwar Dabur and Lina Mudalej and male student Bakr Odeh – as their final project in the course on systems programming in an Arduino environment, <\/span>held in conjunction with Microsoft R&D.<\/p>\n Dabur relates, \u201cIt all started two years ago, when the Faculty provided its Muslim students with a <\/span>mosallah <\/span><\/i>(dedicated prayer room). \u00a0It was of course a very important step for us Muslims who want to pray during the day, but we soon found that there was a little problem: a person who wants to pray in the room has no way of knowing whether it\u2019s vacant or occupied.\u201d<\/span><\/p>\n Unlike prayers with many participants, where men and women gather in the same hall, prayer in small prayer rooms is not mixed. \u201cTherefore it is important for us to know not only if the room is occupied but also who is inside – men or women. We realized that this was a very complex challenge, but we are students at the Technion – there\u2019s no way we would fail to solve all those problems.\u201d<\/span><\/p>\n During the past year, the project year, the three visited many prayer rooms in order to analyze the characteristics that could be monitored during prayers in the <\/span>mosallah<\/span><\/i>, and developed the system, constantly improving it based on experiments. From the outset, it was clear to them that cameras would not be used, because they violate the worshiper\u2019s privacy. Therefore they developed a smart prayer rug equipped with pressure sensors. The rug provides the system with information enabling it to determine whether the <\/span>worshippers in the room are men or women. \u201cWomen and men pray differently,\u201d Dabur explains. \u201cWhen men pray, one of the <\/span>worshippers <\/b>stands in front and the others behind, while women pray in a single row. The order in which they kneel is also different. Therefore, based on the information obtained from the pressure sensors, we can determine the gender of the worshipers without entering the room.\u201d<\/span><\/p>\n The system developed by the three students includes pressure and distance sensors, an Arduino controller and servo motor; software that analyzes the data; and a dedicated app that sends the user prayer reminders on his mobile phone and tells him when the prayer room is vacant or partly vacant. The system can also be used without a smartphone, thanks to an interactive interface based on an LCD touch screen installed outside the prayer room, enabling the user to obtain relevant data and inform the system that he is waiting outside. <\/span><\/p>\n \u201cUsing the system saves the user a lot of time. Everyone knows that time is a rare commodity when you\u2019re a student at the Technion,\u201d concludes Lina. \u201cThis way, instead of standing in line to enter the prayer room, I study at the library and when I see on my phone that the room is vacant, I go there to pray. In the future, we intend to turn the app into a tool for learning prayers and the special movements that go with them.\u201d <\/span><\/p>\n
