Location-Based Augmented Reality With Pervasive Smartphone Sensors: Inside and Beyond Pokemon Go!

Within the design and development of a smartphone, an important phase arises regarding time, which is related to the tuning of the ISP (image signal processor) of the camera. The ISP is an element that allows the adjustment of the images captured by a sensor in order to achieve the best image quality. The ISP implements different image improvement algorithms such as white balancing, denoising, and demosaicing as well as other image enhancement algorithms. The purpose of the ISP tuning process is to configure the parameters of these algorithms so that the processed images are of the highest quality. This task is carried out by the camera tuning engineer, who iteratively adjusts the ISP parameters through trial and error procedures until the desired quality is achieved. The complete adjustment process can be extended to several weeks and even months. The authors present a novel solution based on differential evolution, which allows a first-adjusted approximation of the ISP in a few hours. This work presents an architecture based on an optimization through a differential evolution algorithm with which different ISP tuning tests are carried out, and the good results in quality and time are verified.

“…Pokémon Go is a multiplayer location-based mobile application that was developed by Niantic for the iOS and Android mobile devices, and was released on July 2016, which to this day have attracted worldwide interest and attention [10]. Pokémon Go is a truly mobile application where player is tasked to physically roam an area by utilizing a mobile devices capabilities [11]. The reason which made it so appealing or special is that, Pokémon Go utilizes an innovative, award-wining gameplay mechanics that uses Augmented Reality (AR) technology, it superimpose computer-generated information over your physical surrounding and put virtual creature at a realworld location [12].…”

Fitness and keeping a balanced lifestyle are an important aspect in our daily lives. Being healthy will allow us to conduct our daily activities in a more productive manner. However, it is sidelined by the fact the people now a days are mostly busy with their work and other things, added the fact of the lack of motivation to conduct the physical activities, lead to people not having a balanced life. For that reason, the aim of the developed application is to provide users with an immersive and interactive jogging application which will help in motivating the user into wanting to conduct fitness activities. The interactivity is provided by implementing Geofencing technique, which is by generating a parameter around certain coordinates which when entered by a device will create certain events such as sending notification or directing to a different page. While the immersiveness aspect is implemented using Augmented Reality, which is where a 3D model is anchored into a certain plane which can be seen by using the mobile phones rear camera. The Rapid Development Life Cycle (RDLC) have been chosen as the methodology for the development of the application because it allows developer to iteratively change the system requirements during the development and presentation phase. Functionality testing have been conducted to the developed application.

“…In recent years, AR technology and SG devices are being increasingly tested, especially in professional contexts, such as the industrial [12,13], medical [14], educational and research sectors and many others like the agricultural sector [15][16][17], besides the SG producer companies, are more focused in developing solutions primarily for manufacturing and engineering field [18][19][20]. Interestingly, however, one of first widespread AR results was in the entertainment field with Pokemon Go smartphone application [21].…”

Performance and Usability of Smartglasses for Augmented Reality in Precision Livestock Farming Operations

In recent years, smartglasses for augmented reality are becoming increasingly popular in professional contexts. However, no commercial solutions are available for the agricultural field, despite the potential of this technology to help farmers. Many head-wearable devices in development possess a variety of features that may affect the smartglasses wearing experience. Over the last decades, dairy farms have adopted new technologies to improve their productivity and profit. However, there remains a gap in the literature as regards the application of augmented reality in livestock farms. Head-wearable devices may offer invaluable benefits to farmers, allowing real-time information monitoring of each animal during on-farm activities. The aim of this study was to expand the knowledge base on how augmented reality devices (smartglasses) interact with farming environments, focusing primarily on human perception and usability. Research has been conducted examining the GlassUp F4 smartglasses during animal selection process. Sixteen participants performed the identification and grouping trials in the milking parlor, reading different types of contents on the augmented reality device optical display. Two questionnaires were used to evaluate the perceived workload and usability of the device. Results showed that the information type could influence the perceived workload and the animal identification process. Smart glasses for augmented reality were a useful tool in the animal genetic improvement program offering promising opportunities for adoption in livestock operations in terms of assessing data consultation and information about animals.
