Following wrong suggestions: self-blame in human and computer scenarios
This paper investigates the specific experience of following a suggestion by
an intelligent machine that has a wrong outcome and the emotions people feel.
By adopting a typical task employed in studies on decision-making, we presented
participants with two scenarios in which they follow a suggestion and have a
wrong outcome by either an expert human being or an intelligent machine. We
found a significant decrease in the perceived responsibility on the wrong
choice when the machine offers the suggestion. At present, few studies have
investigated the negative emotions that could arise from a bad outcome after
following the suggestion given by an intelligent system, and how to cope with
the potential distrust that could affect the long-term use of the system and
the cooperation. This preliminary research has implications in the study of
cooperation and decision making with intelligent machines. Further research may
address how to offer the suggestion in order to better cope with user's
self-blame.Comment: To be published in the Proceedings of IFIP Conference on

CodeGazer: Making Code Navigation Easy and Natural with Gaze Input
Navigating source code, an activity common in software development,is time consuming and in need of improvement. We present CodeGazer, a prototype for source code navigation using eye gaze for common navigation functions. These functions include actions such as âGo to Definitionâ and âFind All Usagesâ of an identifier, navigate to files and methods, move back and forth between visited points in code and scrolling. We present user study results showing that many users liked and even preferred the gaze-based navigation, in particular the âGo to Definitionâ function. Gaze-based navigation is also holding up well in completion time when compared to traditional methods. We discuss how eye gaze can be integrated into traditional mouse & keyboard applications in order to make âlook upâ tasks more natural
In Search of a Decision-Making Framework for Involving Users Who Have Learning Disabilities or Sensory Impairments in the Process of Designing Future Technologies
A comprehensive literature review was undertaken in order to identify design approaches that have been employed with users who have learning disabilities or sensory impairment; the factors that influenced their choices and the extent to which the approaches and techniques adopted were successful. There was a huge variation across the corpus regarding whether a justification was offered for the choice of approach and the extent to which those justifications were supported by evidence. In addition there was a lack of comprehensive evaluation of the design approaches. Technology designers who intend working with users with learning disabilities or sensory impairments therefore currently have little to help them decide which design approach might be the most appropriate or effective.</p
Exploring Vision-Based Interfaces: How to Use Your Head in Dual Pointing Tasks
The utility of vision-based face tracking for dual pointing tasks is evaluated. We first describe a 3-D face tracking technique based on real-time parametric motion-stereo, which is non-invasive, robust, and self-initialized. The tracker provides a real-time estimate of a ?frontal face ray? whose intersection with the display surface plane is used as a second stream of input for scrolling or pointing, in paral-lel with hand input. We evaluated the performance of com-bined head/hand input on a box selection and coloring task: users selected boxes with one pointer and colors with a second pointer, or performed both tasks with a single pointer. We found that performance with head and one hand was intermediate between single hand performance and dual hand performance. Our results are consistent with previously reported dual hand conflict in symmetric pointing tasks, and suggest that a head-based input stream should be used for asymmetric control
Keeping an eye on the game: Eye gaze interaction with massively multiplayer online games and virtual communities for motor impaired users.
Online virtual communities are becoming increasingly popular both within the able-bodied and
disabled user communities. These games assume the use of keyboard and mouse as standard
input devices, which in some cases is not appropriate for users with a disability. This paper
explores gaze-based interaction methods and highlights the problems associated with gaze
control of online virtual worlds. The paper then presents a novel âSnap Clutchâ software tool
that addresses these problems and enables gaze control. The tool is tested with an experiment
showing that effective gaze control is possible although task times are longer. Errors caused by
gaze control are identified and potential methods for reducing these are discussed. Finally, the
paper demonstrates that gaze driven locomotion can potentially achieve parity with mouse and
keyboard driven locomotion, and shows that gaze is a viable modality for game based
locomotion both for able-bodied and disabled users alike
Techno-Economic Aspects of Solid Food Wastes into Bio-Manure
Solid waste is health hazard and cause damage to the environment due to improper handling. Solid waste comprises of Industrial Waste (IW), Hazardous Waste (HW), Municipal Solid Waste (MSW), Electronic waste (E-waste), Bio-Medical Waste (BMW) which depend on their supply & characteristics. Food waste or Bio-waste composting and its role in sustainable development is explained in food waste is a growing area of concern with many costs to our community in terms of waste collection, disposal and greenhouse gases. When rotting food ends up in landfill it turns into methane, a greenhouse gas that is particularly damaging to the environment. Composting is biochemical process in which organic materials are biologically degraded, resulting in the production of organic by products and energy in the form of heat. Heat is trapped within the composting mass, leading to the phenomenon of self-heating.This overall process provide us Bio-Manure.
