Development tools for mobile devices in market price information systems

There are already several applications on mobile devices that can be useful in agriculture. For example: GPS-enabled map software, individual cattle identification and tracking software and even complex agricultural systems. These are just beginning to spread in the Hungarian agrifood sector. The possibility of using for agribusiness of mobile internet and mobile tools is increasing. Mobile tools are really suitable for tasks like inspecting the evolution of prices of agricultural products. One of our application development is a mobile extension to access the Market Price Information System run by the Hungarian Agricultural Economics Research Institute. The accessibility of information demanded by market actors can be ensured effectively by using mobile tools. The biggest limitation for PDA is screen size. If it is getting smaller from full screen to PDA-sized and yet further to mobile phone dimensions, user performance drops. The main reason for this is that smaller screens make it more difficult for a user to make good judgements about the usefulness of any particular information. The development methods and tools help us to solve one part of these problems

Impact factors for mobile internet applications in the agri-food sectors

Mobile communication and the mobile Internet can provide important opportunities, economic advantages for enterprises end organisations and support their more efficient operating as they can be used anytime and anywhere. We can make their wide spread use, innovative effects and advantages economical if we consider the effect system of technologies and services. The technological, social and economical complex effect system puts a pressure on the spreading of business applications. The types of applicable equipment are increasing. According to social aspects there are four player groups: manufacturers, enterprises, customers and workers. The Internet technology and the Internet network have become essential communication tools in business processes recently. Using the Internet by means of mobile appliances increases the possibilities. By studying the business process the expenses, advantages, disadvantages can well be seen. Nowadays these applications are more and more successful in areas such as agriculture, different parts of the food industry, extension services, precision agriculture and logistics. It can be stated that the international and the Hungarian development tendencies of the mobile Internet, the RTD Programmes of EU help the wide-spread use of mobile services. The rapid development of the Hungarian domestic mobile market over the last years is the basis for the wide spread use of new broadband mobile services and applications. This system can contribute to the development of agriculture, enterprises and rural areas and can support production, commerce, services and product tracing. But for successful applications we have to consider the impact factors

Study of affordances of iPads and teacher's private theories

Post-PC TouchPad mobile devices are increasingly being used in educational contexts. Growing investment isplanned by higher education institutions in Hong Kong and by the HKSAR Education Bureau in relation to educational uses ofTouchPad technology. However, current research intoeducational applications of this technology is limited. This paper reports an ongoing qualitative study that investigates how higher education teachers use iPad technology to facilitate their practice. The emergent study results provide insight intoboth the educational affordances of iPad technology and theways in which teachers’ personal or private theories mediate these affordances and transform through the process. The studyoutcomes will contribute to theoretical understanding of higher education teacher changes through adoption of technology. Furthermore, the outcomes will provide a set of recommendations for applications of TouchPad technology inhigher education and ways to support teachers to effectively adopt such technology in their practices.published_or_final_versio

Evaluating the social acceptability of voice based smartwatch search

There has been a recent increase in the number of wearable (e.g. smartwatch, interactive glasses, etc.) devices available. Coupled with this there has been a surge in the number of searches that occur on mobile devices. Given these trends it is inevitable that search will become a part of wearable interaction. Given the form factor and display capabilities of wearables this will probably require a different type of search interaction to what is currently used in mobile search. This paper presents the results of a user study focusing on users’ perceptions of the use of smartwatches for search. We pay particular attention to social acceptability of different search scenarios, focussing on in-put method, device form and information need. Our findings indicate that audience and location heavily influence whether people will perform a voice based search. The results will help search system developers to support search on smartwatches

A Systematic Review on Integrating MALL in English Language Teaching

The use of technology in language learning has been going on for a long time. Many technological characteristics are currently utilized in language learning as a result of the rapid growth of technology. MALL is one of them. This study aims to review integrating MALL in English language teaching (ELT). The study employed a systematic review checklist as a method. Findings suggest that MALL has a good impact on students' English language development, which leads to positive outcomes, according to the overall findings. Parents, teachers, and students expressed an interest in promoting MALL in ELT. Teachers were enthusiastic about MALL and felt that it could be utilized to teach English. MALL also had a positive influence in educational contexts, with students enthusiastic about utilizing it in English classes. They also believe that MALL provides them with numerous benefits when performing their tasks. Due to the challenges teachers and students encounter in applying and using MALL in ELT, such as psychological, pedagogical, and technical limits, stakeholders are expected to develop solutions and policies to achieve effective technology-oriented learning in ELT.  Keywords: Systematic review, MALL, EL
