The Influence of the Interface Button Design of Touch Screens on Operation and Interpretation by Elderly and Middle-Aged Adults

Body function begins to decline in middle age, with changes becoming increasingly noticeable over time. With the popularization of educational and information technology, people know more about healthcare and are becoming accustomed to self-testing using health equipment. Technological changes are reflected in products, which present innovations including the switch from traditional to touch-controlled interface designs. This can cause difficulties in the interpretation and interface operation for older adults, who may be facing physiological and psychological alterations. Understanding users’ physiological limitations has become an important aspect of product design. This study explored the effects of physiological limitations on touch-screen operation in middle-aged and elderly people, specifically regarding button type, display position, and button size. A total of 64 participants were included in the study: 32 middle-aged people (aged 45–64 years) and 32 elderly people (65 years of age and older). Each participant was asked to complete 32 tasks (two button categories × four button sizes × four presentation positions). The results revealed no differences between the elderly and the middle-aged groups with regard to the interpretation of image buttons and text buttons; however, button size affected the operation and interpretation time. Middle-aged participants demonstrated good interpretation performance when the buttons were displayed in the upper or lower part of the screen, whereas elderly participants only had a good interpretation performance when the buttons were in the upper part. For both groups, the ideal image button size was 16 mm with a text font size of 22.

IMPLEMENTASI METODE LBS (LOCATION BASED SERVICE ) PADA PENCARIAN RUTE PANTI ASUHAN DI KOTA MAKASSAR

Many people want to support the orphanage but still have difficulty getting accurate information about the orphanage and the location of the orphanage so they have to go to the social service office or by asking the community to get information about the local orphanage. This surely has an impact on the activities of donors who donates on a regular basis without knowing the conditions of other orphanages in the local area that are more likely to receive the donation. This application applies a Location Based Service (LBS) system that is able to detect the location of an orphanage, then can provide information services in accordance with the user's location. LBS is a location-based service, which is an internet-based service that is able to display position geographically from a smartphone or provide location information from the destined address. The aim of this research is to create an application that can provide information to donors through android about the location of orphanages in Makassar City with navigation features and display information related to orphanages to make it easier for donors to conclude which orphanages need more donations. This application can provide information for donors of android users to get convenience in finding and knowing the location of orphanages in the city of Makassar through an android mobile device to do donation activities.

Display in the Wild (DIW): An Adaptive Projection-Imaging System to Screen Geometry in Real Time

TVs and monitors are among the most widely used displays in various environments. However, they have limitations in their physical display conditions, such as a fixed size/position and a rigid/flat space. In this paper, we suggest a new “Display in the Wild” (DIW) concept to overcome the aforementioned problems. Our proposed DIW system allows us to display a flexibly large screen on dynamic non-planar surfaces at an arbitrary display position. To implement our DIW concept practically, we choose a projector as the hardware configuration in order to generate a screen anywhere with different sizes. However, distortion occurs when the projector displays content on a surface that is dynamic and/or non-planar. Therefore, we propose a distortion correction method for DIW to overcome the aforementioned surface constraints. Since projectors are not capture devices, we propose using a depth camera to determine the distortions on the surfaces quickly. We also propose DIW-specific calibration and fast/precise correction methods. Our calibration method is constructed to detect the projection surface easily and quickly, and also allows our proposed system to accommodate the intrinsic parameters such as a display resolution and field of view. We accomplish a fast undistortion process of the projector by considering only surface boundary pixels, which enables our method to run in real time. In our comprehensive experiments, the proposed DIW system generates undistorted screens such as TVs and monitors on dynamic non-planar surfaces at an arbitrary display position with Unmanned Aerial Vehicles (UAVs) in a fast and accurate manner, demonstrating its usefulness in practical DIW scenarios.

ACR (AUTOMATIC CONTROL ROBOT) BERBASIS ATMEGA 8535 SEBAGAI APLIKASI MODEL ROBOT MENGGUNAKAN REL

Arif Setiawan, Subali, in this paper explain that a fixed rail track used as a railway line. Application of rail as a direct path not only to train. However, there are also robots that use rail movement path. Rail crossings are used as the robot is not made of steel, but a line. This robot uses a single rail line is black with a white stripe background of a width adapted to the sensor mounted on the robot. Photodiode sensor lines will be detected, and then transmitted to the microcontroller 8535 as the brain or the source of the instruction that has been programmed. 8535 will detect the sensor output and then process the data received to proceed to the Driver that is connected to the DC motor. The output of the microcontroller 8535 will also be displayed through the LCD as the display position of the sensor and input characters. As an added speed control robot 4x1 keypad which will give instruction in the form of characters into the Microcontroller.
