排球競賽即時記錄與分析之應用程式數據系統設計與開發

Abstract

排球在國內是越來越普及化的一項運動，也深受許多人喜愛。全國各規模之排球競賽逐年增加，報名隊數也逐年上升，相對球技表現之競爭力也越漸提升。然而，能夠有效反應球隊表現之排球競賽記錄，目前幾乎仍是使用紙本形式記錄。排球記錄表有助於釐清球隊在競賽中遭遇的困境，以及各球員表現狀況與得失分原因。本研究希冀藉由科技導入，讓記錄分析的效用提升。妥善運用即時運算的特性，將數據資料在比賽中呈現給教練進行戰術調配決策。本研究開發設計一款排球競賽即時記錄與分析之應用程式數據系統，提升排球競賽數據的應用層面，進一步提升隊伍競賽表現。透過相關文獻探討：排球記錄分析、資訊視覺化、互動設計、介面設計、數據分析等面向，來進行研究之設計與開發，並以適用於即時記錄的介面為主軸進行設計。而後訪談六位專業教練，了解在比賽中會影響決策的關鍵因素為：得失分因素、重點球員、落點位置。系統設計主要分為兩大項目：比賽記錄與數據圖表呈現。在設計開發完成後，使用量表與訪談進行評估受測者對於系統之滿意度，分別使用了：績效量測法、SUS系統易用性量表、QUIS使用者互動滿意度量表、淨推薦分數NPS調查問卷、訪談與意見回饋等方式，來評估分析受測者之主觀感受以及系統成效。在比賽記錄與圖表呈現的回餽上，圖表呈現部分得到較佳表現與肯定；受測者在記錄比賽時受到較多挫折，與學習時間和介面熟悉度有關。不過受測者皆認同能透過練習與學習的方式熟悉操作，並有自信操作系統。本系統改變了傳統紙本的記錄方式，並且加速了比賽之數據計算的時間，提供更即時的分析數據給教練與球員參考。

In Taiwan, volleyball had become more and more popular. The number of volleyball team has increased year after year in every domestic competitions and the competitiveness has also increased. However, the way to record the performance of teams hasn’t changed so much. Teams record each skill’s points on papers. The Forms help teams to find out the key point of competition result and the performance of all players. However, paper forms need time to calculate the numbers and are hard to read in competition. In this study, we tried to enhance the way of recoding, which can influent the result of competitions. And we design an application, which can get in-time calculated information for coaches to match tactics in games. In order to design a better system for in-time use, we study papers about volleyball performance analysis, infographic, human-computer interaction, user interface, and analysis system to design and develop this analysis application. After interviewing 6 professional coaches, we found out the key points to adjust their tactical decisions are: winning and losing factors, key players, and the ball’s falling position. This system has two main functions: recording and information presenting. We used performance measurement, System Usability Scale (SUS), The Questionnaire For User Interaction Satisfaction (QUIS), Net Promoter Score (NPS) and interviews to assess the subjective feelings of the subjects and the system effectiveness. The result is that information presenting got better performance and affirmation. Subjects were more frustrated when recording competitions, related to less learning time and low interface familiarity. However, the subjects have confident to operate the system by themself after practicing and learning. This system changed the way of recording the performance of teams in competitions, which enhances the time of calculating data and provides in-time analysis for coaches or players to reference.
