In this paper, we investigate the effectiveness of two distinct techniques (Special Moment Approach & Spatial Frequency Approach) for reviewing the lifelogs, which were collected by lifeloggers who were willing to use a wearable camera and a bracelet simultaneously for two days. Generally, Special moment approach is a technique for extracting episodic events and Spatial frequency approach is a technique for associating visual with temporal and location information, especially heat map is applied as the spatial data for expressing frequency awareness. Based on that, the participants were asked to fill in two post-study questionnaires for evaluating the effectiveness of those two techniques and their combination. The preliminary result showed the positive potential of exploring individual lifelogs using our approaches.

Psammodiscus nitidus (Gregory) Round & D.G. Mann (1980: 371) (Figs 1–18) Basionym: Coscinodiscus nitidus Gregory (1857: 499, pl. 10, fig. 45) TYPE:— UK: Scotland, Lamlash Bay (BM 1343, Hendey 1964: 76, syntype). Size and shape: Cells solitary, attached to sand grains (Figs 1a, b). Valves circular to slightly elliptic in valve view (Figs 2–4). Valve diameter 13.5–28.5 µm, 8–9 striae in 10 µm, 8 areolae in 10 µm (Table 1). Plastids and nucleus: Discoid plastids located along valve surface, number ca. 90 (Fig. 5). Nucleus lies at cell centre (Fig.5). Fine structures of valve: Valve face flat (Fig. 6), striae radiate, reaching mantle (Fig. 6). Areola on valve face (Figs 7, 8) and mantle (Fig. 8) occluded by rotae with 2–3 spokes. Internal views of small valves not observed. Larger valves (Figs 9 and 12) originate from same frustule. Striae and areolae of large valves morphologically similar to those in smaller valves (Figs 9–11); occasionally areola abnormalities visible (Fig. 10). Spokes in areolae not observed from internal view (Fig. 14). Rimoportula: Number of rimoportulae 0–2 (Figs 6, 12, 15) per valve. Rimoportula external opening located near valve centre (Figs 6, 7). Some valves lack central rimoportula (Fig. 15). In larger valves, external opening of rimoportula observed near valve margin (Fig. 10). In internal view, two rimoportulae located at opposite sides near valve margin (Figs 12–14). Rimoportula sessile with simple slit surrounded by ridge (Figs 13, 14). Central small pore: Central small pore located near valve centre (Figs 6, 7). Additional small pore: In larger valve, external opening of small pore observed near valve margin (Fig. 10). Additional small pore situated close to rimoportula near margin (Fig. 14). Cingulum: epicingulum consisting of three open bands: valvocopula (VC), second (2B) and third (3B) bands (Figs 17a, b). Valvocopula and second girdle bands open at 180° to each other (Figs 15, 16, 18). VC with two rows of pores (Fig. 16), its opening covered by ligula of 2B (Figs 16, 17a, 17b). 2B with single row of pores (Fig. 17a, b). 3B narrow with single row of triangular non-occluded pores (Figs 17a, b).

In this paper, we introduce a tilting interface that controls direction based applications in ubiquitous environments. A tilt interface is useful for situations that require remote and quick interactions or that are executed in public spaces. We explored the proposed tilting interface with different application types and classified the tilting interaction techniques. Augmenting objects with sensors can potentially address the problem of the lack of intuitive and natural input devices in ubiquitous environments. We have conducted an experiment to test the usability of the proposed tilting interface to compare it with conventional input devices and hand gestures. The experiment results showed greater improvement of the tilt gestures in comparison with hand gestures in terms of speed, accuracy, and user satisfaction., Comment: 13 pages, 10 figures
