The communication between people with normal hearing with those having hearing or speech impairment is difficult. Learning a new alphabet is not always easy, especially when it is a sign language alphabet, which requires both hand skills and practice. This paper presents the GyGSLA system, standing as a completely portable setup created to help inexperienced people in the process of learning a new sign language alphabet. To achieve it, a computer/mobile game-interface and an hardware device, a wearable glove, were developed. When interacting with the computer or mobile device, using the wearable glove, the user is asked to represent alphabet letters and digits, by replicating the hand and fingers positions shown in a screen. The glove then sends the hand and fingers positions to the computer/mobile device using a wireless interface, which interprets the letter or digit that is being done by the user, and gives it a corresponding score. The system was tested with three completely inexperience sign language subjects, achieving a 76 % average recognition ratio for the Portuguese sign language alphabet.
In the globalized world, good products may not be enough to reach potential clients if creative marketing strategies are not well delineated. Public relations are also important when it comes to capture clients attention, making the first contact between them and companies products while being persuasive enough to trust that the company has the right products to fit their needs. A virtual public relations is purposed, combining technology and a human like public relations capable of interacting with potential clients located 180 degrees in front of the installation, by using gestures and sound. Four Microsoft Kinects were used to develop the 180 degrees model for interaction, which allows tracking and recognition of gestures, sound sources, voice commands, extract the face and body of the user and track users positions (heat map).
As Human Computer Interaction technologies evolve, they are supporting the generation of innovative solutions in a broad range of domains. Among them, Serious Games are defined as new type of computer game that is capable of stimulating users to learn, by playing and competing against themselves, against other users or against a computer application. While it could be applied to a broad range of fields and ages, these games are becoming especially relevant in educational contexts and for the most recent generation of students that is growing in a new technological environment, very different from the one we had some years ago. However, in order to become fully accepted as a teaching/learning tool in both formal and informal contexts, this technology has still to overcome several challenges. Given these considerations, this chapter makes a state-of-the-art review of several works that were done in this field, followed by the description of two real world projects, helping to understand the applicability of this technology, but also its inherent challenges.
Pool and billiards are amongst a family of games played on a table with six pockets along the rails. This paper presents an augmented reality tool designed to assist unskilled or amateur players of such games. The system is based on a projector and a Kinect 2 sensor placed above the table, acquiring and processing the game on-the-fly. By using depth information and detecting the table's rails (borders), the balls' positions, the cue direction, and the strike of the ball, computations predict the resulting balls' trajectories after the shot is played. These resultstrajectories, visual effects, and menus-are visually output by the projector, making them visible on the snooker table. The system achieves a shot prediction accuracy of 98% when no bouncing occurs.
In the globalized world, possessing good products may not be enough to reach potential clients unless creative marketing strategies are well delineated. In this context, public relations are also important when it comes to capture the client's attention, making the first contact between the clients and the company's products, while being persuasive enough to make them confident that the company has the right products to fit their needs. Three virtual public relations installations were purposed in this chapter, combining technology with a human like public relations ability, capable of interacting with potential clients located in front of the installation, at angles of up to 57º (degrees), 180º and 360º, respectively. From one to several Microsoft Kinects were used to develop the three interaction models, which allows tracking and recognition of users' gestures and positions (heat map), sound sources, voice commands and face and body extraction of the user interacting with the installation.
With new marketing strategies and technologies, new demands arise, and the standard public relation or salesperson is not enough, costumers tend to have higher standards while companies try to capture their attention, requiring the use of creative contents and ideas. For this purpose, this article describes how an interactive holographic installation was developed, making use of a holographic technology to call attention of potential clients. This is achieved by working as a host or showing a product advertising the company. The installation consists in a 360 degree (8 view) holographic avatar or object and optionality, also a screen, where a set of menus with videos, images and textual contents are presented. It uses several Microsoft Kinect sensors for enabling user (and other persons) tracking and natural interaction around the installation, through gestures and speech while building several statistics of the visualized content. All those statistics can be analyzed on-the-fly by the company to understand the success of the event.
