本論文では,Webデザインがユーザに与える印象と,記憶される情報量との関係を明らかにするため,Webアンケート調査と被験者実験(眼球運動測定,ヒアリング)を通して調べた結果について報告する.まずSD法によりWebデザインが与える印象,評価を分析した結果,「利便性」「文字の可読性」「エンターテイメント性」というWeb評価因子が抽出された.また共分散構造分析を通し,良いデザインと思われるには「利便性」「エンターテイメント性」,再利用意向を高めるには「利便性」の影響が大きいことを明らかにした.またWeb閲覧時のユーザの眼球運動測定,閲覧後のヒアリングにより,注視された情報量と記憶された情報量とは相関関係があること.また,注視された情報量は「利便性」「エンターテイメント性」,記憶された情報量は「利便性」の影響が大きいことを示した.つまり,良いデザインと思われる為にも,再利用意向を高める為にも,情報が注視される為にも,記憶に残す為にも,「次に何をすればいいか迷わない」「タイトルが見つけやすい」などユーザのメンタルモデルに即した「利便性」をWeb上にデザインすることが重要となることが明らかになった.

It is known that flying fish perform long-range flight in the air in order to escape from predators such as tuna and swordfish. During the unsteady flight, ground effect enables the flying fish execute to flight for the maximum range and longest time. In this study, it was investigated a basic characteristic of the flow around the flying fish fin in ground effect, in order to understand the flying fish gliding performance quantitatively. The streamwise velocity profiles around the airfoil model were measured by a high time-resolved PIV (particle image velocimetry) in an open loop wind tunnel. A moving ground essential to generate the ground effect was supplied using a rotating disk. Two plates were put in tandem as the test wing model of a pectoral fin and a ventral fin of the flying fish. It was found that decreasing the height of the airfoil model caused a larger difference between the velocity in the suction surface side and that in the pressure surface side of the pectoral fin model.

Any wind instrument can sound due to the vibration of the air, expiration flow inside of the wind instrument. In case of a trumpet or a clarinet, a mouth or a reed helps to sound variable tones. In case of a flute, there is no mechanical vibration. We would like to investigate more detail about the flow and the vibration with sound inside or outside of the flute, in order to understand the mechanism of the wind instrument and to aid in the manufacture of the good instrument. In this report, a Japanese traditional bamboo flute was used in the experiment. The dynamic PIN technique was applied to measure the vibration. 2 kinds of experiments were done. The Argon-gas flow with different tone inside/outside of the bamboo flute was measured using a high frequency pulse laser. Oil mist was used as the tracer particles. Then, we also tried to measure the flow in bamboo flute when a human player played, using a CW-laser and the water-mist as the tracers. We successfully measured that the periodical flow near a hole of the bamboo flute went out from and came into the flute at 200-500Hz dependent on the tone.

前報では,Webデザインがユーザに与える印象と記憶される情報量との関係性について報告した.この分析過程において,SD法に基づくWebアンケート調査を524名に対して実施し,「利便性」「文字の可読性」「エンターテイメント性」というWeb評価因子が抽出された結果についても明記した.本報告では,前報で用いたSD法による印象評価構造の分析を拡張する多次元尺度構成法による分析を検討する.通常SD法において各ユーザの印象は多くの項目,設問,すなわち多変量として収集される.このユーザの印象を2次元に情報圧縮した際の評価形容詞群と抽出された因子との関係性,評価形容詞群とWebサイトとの関係性,についての可視化を試みた.分析の結果,提案手法が従来法に加え,さらなる印象把握に向け有効なアプローチの1つであることが示された.
