    The parallax effect describes the displacement between the perceived and detected touch locations on a touch-enabled surface. Parallax is a key usability challenge for interactive displays, particularly for those that require thick layers of glass between the screen and the touch surface to protect them from vandalism. To address this challenge, we present EyePACT, a method that compensates for input error caused by parallax on public displays. Our method uses a display-mounted depth camera to detect the user's 3D eye position in front of the display and the detected touch location to predict the perceived touch location on the surface. We evaluate our method in two user studies in terms of parallax correction performance as well as multi-user support. Our evaluations demonstrate that EyePACT (1) significantly improves accuracy even with varying gap distances between the touch surface and the display, (2) adapts to different levels of parallax by resulting in significantly larger corrections with larger gap distances, and (3) maintains a significantly large distance between two users' fingers when interacting with the same object. These findings are promising for the development of future parallax-free interactive displays

    An interactive editor for definition of touch-sensitive zones for a graphic display

    In the continuing effort to develop more efficient man-machine communications methods, touch displays have shown potential as straightforward input systems. The development of software necessary to handle such systems, however, can become tedious. In order to reduce the need for redundant programming, a touch editor has been developed which allows a programmer to interactively define touch-sensitive areas for a graphic display. The information produced during the editing process is written to a data file, which can be accessed easily when needed by an application program. This paper outlines the structure, logic, and use of the editor, as well as the hardware with which it is presently compatible

    Get PDF
    We propose a model driven design and development methodology augmented with formal validation and verification (V&V) for the development of mobile health systems. Systems which deliver healthcare services remotely should be developed using robust and trusted engineering technologies. The methodology instantiates steps in the MDA trajectory using formal methods to verify critical properties of models, to test preservation of those properties in the derived implementations and to effect model transformations by correctness preserving transformations. The methodology is described and some initial modelling is reported

    The goal of the research is to find the under taking of motivation giving, the significant effect of motivation, and which variable motivation that has more dominantly influence on working productivity of the employees. Means of analysis that used to find the motivation and working productivity of the employees was scale span. To find the influence of Motivation (X) on working productivity of the employees (Y) was used double linear regression analysis by F test by comparing the value of F counting and F table. The result of averaged calculation in scale span for motivation variable (the need of existence), could be obtained a number of 118, which meant that motivation (the need of existence) given to the employees could be categorized as fullfilled. Based on the result of averaged calculation of scale span for motivation variable (the need to get in touch with others) could be obtained a number of 117 which meant that motivation (the need to get in touch with others) given to the employees could be categorized as fullfilled. Based on the result of averaged calculation of scale span for motivation variable (the need of development) could be obtained a number of 117,5 which meant that motivation (the need of development) given to the employees could be categorized as fullfilled. Based on the result of averaged calculation of scale span for working productivity of the employees, could be obtained a number of 130,33 which meant that working productivity of the employees could be categorized on very high level. The calculation of double linear regression analysis Y = -0,420 + 0,626 X1 + 0,742 X2 + 0,368 X3 + e, R2 square as much as the need to get in touch with others showed that motivation variable (the need to get in touch with others) contributed greatly on the working productivity of the employees. The result of F test conducted by comparing F counting with F table on real standard  = 0,05. F counting was 30,205 > F table 2,990. The results proved that simultaneous compensation could give significant influence on the working productivity of the employees. Based on the data above, the researcher could draw a conclusion that motivation (the need to get in touch with others) had predominantly influence on the working productivity of the employees

    Social touch and human development.

    Social touch is a powerful force in human development, shaping social reward, attachment, cognitive, communication, and emotional regulation from infancy and throughout life. In this review, we consider the question of how social touch is defined from both bottom-up and top-down perspectives. In the former category, there is a clear role for the C-touch (CT) system, which constitutes a unique submodality that mediates affective touch and contrasts with discriminative touch. Top-down factors such as culture, personal relationships, setting, gender, and other contextual influences are also important in defining and interpreting social touch. The critical role of social touch throughout the lifespan is considered, with special attention to infancy and young childhood, a time during which social touch and its neural, behavioral, and physiological contingencies contribute to reinforcement-based learning and impact a variety of developmental trajectories. Finally, the role of social touch in an example of disordered development -autism spectrum disorder-is reviewed

    Infancy started from 0-12 months which was characterized by rapid growth and physical changes accompanied by changes in nutritional needs to optimize the growth and development of the baby by providing touch, motion and other stimulation combinations. The research was purposed to know the effect of Touch Therapy on nutritional status and development on infants in Gayaman Village, Mojokerto Regency. The research design used one group pre-post test design. The population were infants in Gayaman Village, Mojokerto Regency, 70 respondents. The sample was 69 infants (0-18 months) in Gayaman Village, Mojokerto Regency, who were obtained by purposive sampling. Measuring instruments were used to assess nutritional status and denver II forms to assess the progress. The research was done on July 28 to August 25, 2018. Statistical test used Wilcoxon Signed Rank Test. The results showed that nutritional status before being given touch therapy was normal as many as 57 (83%) respondents, and the development after being given touch therapy increased to 66 (96%) respondents. The development before being given touch therapy was normal as many as 27 (39%) respondents with Ï = 0.003. This showed that there was an effect on touch therapy to their nutritional status. The nutritional status after being given a touch therapy increased to 57 (83%) respondents with Ï = 0.008. This showed that there was an effect of touch therapy on their development. Massaging was a fun way to help strengthening the bond between mother and child. This was the key to baby's development. &nbsp

    Bayesian perception of touch for control of robot emotion

    Get PDF
    In this paper, we present a Bayesian approach for perception of touch and control of robot emotion. Touch is an important sensing modality for the development of social robots, and it is used in this work as stimulus through a human-robot interaction. A Bayesian framework is proposed for perception of various types of touch. This method together with a sequential analysis approach allow the robot to accumulate evidence from the interaction with humans to achieve accurate touch perception for adaptable control of robot emotions. Facial expressions are used to represent the emotions of the iCub humanoid. Emotions in the robotic platform, based on facial expressions, are handled by a control architecture that works with the output from the touch perception process. We validate the accuracy of our system with simulated and real robot touch experiments. Results from this work show that our method is suitable and accurate for perception of touch to control robot emotions, which is essential for the development of sociable robots

    Developing a Multi-Touch Map Application for a Large Screen in a Nature Centre

    Get PDF
    The paper describes the development of a research prototype of a multi-touch map application for multi-use on a large multi-touch screen intended for a nature centre. The presented system and the development steps provide insight into what can be expected when similar systems are designed. A number of new considerations regarding multi-touch interaction, map browsing, and user needs for multi-use have been taken into account during the challenging ongoing development. These considerations include making a simple user interface used with intuitive, continuous and simultaneous gestures for map browsing, and taking different kinds of users and their needs to interact with each other into account. Since multi-user map applications in multi-touch environments are still rare, the given considerations may be helpful for the future development of similar map applications intended for public spaces
