Description

Due Week 3 and worth 180 points

  1. The following resources may be helpful when completing this assignment.Computer applications that run on desktop and laptop computers have, for a long time, been designed to be driven by dragging and clicking a mouse. With the introduction of tablet personal computers, the trend has shifted toward using touch-based screens. We now have access to touch-based TVs, touch-based monitors, touch-based laptops and touch-based tablets. Touch and multi-touch devices provide end users with the ability to interact physically with an application much more naturally.

    Imagine that you are the Information Technology Director of a major chain restaurant, and you have been assigned to design a menu ordering application that can run on all devices. Examine whether using a touch-screen monitor, a tablet, or using a mouse to select menu items to place an order would be most efficient. Speculate how employees would interact with these devices and the type of emotional reaction that customers and employees will experience while placing a beverage, appetizer or entrée order.

    Write a four to five (4-5) page paper in which you:
    1. Differentiate between the interaction types and styles that apply to multi-touch screens and applications running on them.
    2. Determine the conceptual model that you would use when designing a product for your restaurant.
    3. Describe the key analogies and concepts these monitors expose to users, including the task-domain objects users manipulate on the screen.
    4. Determine one (1) utility / tool in an application for touch-based and mouse-drive screens that should be designed with memory retention / recall. Provide a rationale for your response.
    5. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources. You may use the resources above or others of your choosing.
    6. Format your assignment according to the following formatting requirements:
      1. This course requires use of new Strayer Writing Standards (SWS). The format is different from other Strayer University courses. Please take a moment to review the SWS documentation for details.
      2. Typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides.
      3. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page is not included in the required assignment page length.
      4. Include a reference page. Citations and references must follow SWS format. The reference page is not included in the required page length.

    The specific course learning outcomes associated with this assignment are:
    • Describe the relationship between the cognitive principles and their application to interfaces and products.
    • Explain the conceptual terms for analyzing human interaction with affordance, conceptual models, and feedback.
    • Use technology and information resources to research issues in human-computer interaction.
    • Write clearly and concisely about human-computer interaction topics using proper writing mechanics and technical style conventions.
    Grading for this assignment will be based on answer quality, logic / organization of the paper, and language and writing skills, using this rubric.
  2. By submitting this paper, you agree: (1) that you are submitting your paper to be used and stored as part of the SafeAssign™ services in accordance with the Blackboard Privacy Policy; (2) that your institution may use your paper in accordance with your institution's policies; and (3) that your use of SafeAssign will be without recourse against Blackboard Inc. and its affiliates.

Introduction
Multi-touch is the technology that allows a touchscreen to recognize more than one point
of contact without conventional input devices. Multi-touch uses screens or touchpad to
communicate with the system as well as software or applications that are user-defined, for
instance, menus or logs. The use of multi-touch is rapidly being integrated into businesses almost
every device being used today. However, computers have for a long time used mouse driven
techniques to navigate screens. Multi-touch and mouse driven techniques work using similar
principles, but instead of interactive touch, a mouse controls cursor movements over a surface to
make selections. This paper discusses the different interaction types and styles applied by multitouch technology. The paper also includes a conceptual model for designing a multi-touch menu
product for a company as well as the concepts the monitors will expose to users for
manipulation.
1. Interactive types
According to Leftheriotis & Chorianopoulos, (2016), different multi-touch technologies apply
different interaction principles and styles
i. Surface Acoustic wave
SAW is a multi-touch technology that applies ultrasonic waves over the touchscreen
surface. When it is touched, the surface absorbs waves which register a change in ultrasonic
waves in turn. The position of the point of absorption sends signals of information to be
processed. However, contaminants or any other outside elements can damage or interfere with
the functionality of the touchpad.

Resistive sensors
Resistive touchpads contain several layers, but the most important ones are two thin

resistive and metallic electrically conductive layers separated by a thin layer of space. During the
interaction, the layers get connected at certain points causing a change in elec...
