HCI is (Human Computer Interaction) Answer the following five statements by first stating whether it is true or false and then given one sentence for justifying your answer a) You drag a folder to make a copy of its contents. An animation appears on the screen, showing files moving from one folder to another. This is an example of feedback. b) In augmented reality a screen is composed of a computer animation of the reality. c) The Model Human Processor is used in HCI to model complex cognitive processes d) Petri Nets can be helpful in modeling concurrent activities in a user interface. e) Gestalt is important to HCI as it offers tools to understand scenes.

MG 20 (create a specified custom function) My Soluti Create a Function - [Problem written by Ryan] A person works out 4 days over the course of a week and is trying to calculate their range of steps for days they work out versus the days they do not. They decided to analyze the data by using the number of steps each day that their watch collected over a two week span, Instead of assigning each day as a workout day or a nonworkout day, they decide to just assume workout days are any day that their step count is above the median step count for the two week span. Write a function that analyzes her steps (in thousands) in vector s (already created in given code). This function should categorize their steps into separate arrays for workout and non-workout days. It should then output the range for workout days as a 1x2 array named Max Step Range and output the range for non-workout days as a 1x2 array named Min_Step Range. These arrays should posess the minimum value in the first column and…

17. A chessboard is an 8 x 8 grid. A knight can move up two squares plus one square to the left or right, or up one plus two squares to the left or right. For a knight in the position shown, determine the number of paths to the top of the board, moving upward at all times. Describe how you solved the problem. (A: /2)(C: 14)

Problem B. Musical Key ConversionThe chromatic scale is a 12-note scale in music in which all notes are evenly spaced: that is, the ratio of the frequency between any two consecutive notes is constant. The notes are typically labeled in the following sequence: A, A#, B, C, C#, D, D#, E, F, F#, G, G# After G#, the labels loop back and start over with A (one octave higher). To convert between musical keys, you can shift all notes in a piece of music a constant number of steps along the scale above. For example, the sequence of notes E, E, F, G, G, F, E, D, C, C, D, E, E, D, D can be converted to another musical key by shifting everything up three steps: E, E, F, G, G, F, E, D, C, C, D, E, E, D, D G, G, G#, A#, A#, G#, G, F, D#, D#, F, G, G, F, F Notice that G was converted to A#, since going three steps up required us to loop off of the top of the scale back to the bottom: G -> G# -> A -> A#. Technically we should note that this would be A# of the next octave up, but we’ll…

7: Exams.cpp) Suppose a teacher weights the four exams he gives 10%, 25%, 30%, and 35%. Write a program that reads ten sets of four grades, prints the weighted average of each set, and prints the unweighted average of each test. The number of students should be in a global constant.

For such keys, the old value should be subtracted by the value of the same key in d2. If the new value of a key becomes smaller than 0, set the new value to zero.

(ms excel   In Moray, employees have Wednesdays and Thursdays off, and the following holidays: January 1, February 12, April 5, May 4, July 21, October 10-12, December 24-26. Design a spreadsheet in which the user can enter start and end dates, and the worksheet returns the total number of working days? Your spreadsheet should work for end dates entered up to and including December 31, 2030. Use formulas to generate the dates of the holidays. The result should be blank if no dates are entered.

2, Towers of Hanoi Problem. (10 points) The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. Answer the following questions. (1) Determine a state representation for this problem. (4points) (2) What is the size of the state space? (3 points) (3) Supposing K=3, N=4, what is the start state by using your proposed state representation method and what is the goal state? (3 points)

Huffman Code[Problem Description]For an English article, the frequency of occurrence of 26 lowercase letters is counted, and then they are encoded by Hoffman code.[Basic Requirements]1)      Read the original text file from the file and display the text on the screen..2)      Output the number of occurrences of 26 English lowercase letters, and the corresponding Hoffman code... Below is the data to be displayed  At present, most of the dynamic sign language recognition is only for sign language words,the continuous sign language sentence recognition research and the corresponding results are less, because the segmentation of such sentence is very difficult. In this paper, a sign languagesentence recognition algorithm is proposed based on weighted key frames. Key frames can be regardedas the basic unit of sign word, therefore, according to the key frames we can get related vocabularies, and thus we can further organize these vocabularies into meaningful sentence. Such work can avoid the…
