Enhancing people’s exercise adherence through technology remains an important research challenge. We propose a novel approach for a system supporting walking that draws from basic findings in neuroscience research. Our shoe-based prototype senses a person’s footsteps and alters in real-time the frequency spectra of the sound they produce while walking. The resulting sounds are consistent with those produced by either a lighter or heavier body. Our user study showed that modified walking sounds change one’s own perceived body weight and lead to a related gait pattern. In particular, augmenting the high frequencies of the sound leads to the perception of having a thinner body and enhances the motivation for physical activity inducing a more dynamic swing and a shorter heel strike. We here discuss the opportunities and the questions our findings open. date: 2015-04-23 publisher: Association for Computing Machinery official_url: http://dx.doi.org/10.1145/2702123.2702374 vfaculties: VFBRS oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_source: Manually entered elements_id: 1024782 doi: 10.1145/2702123.2702374 isbn_13: 9781450331456 lyricists_name: Berthouze, Nadia lyricists_name: Marquardt, Nicolai lyricists_name: Tajadura-Jimenez, Ana lyricists_id: NBERT19 lyricists_id: NMARQ26 lyricists_id: ATAJA50 full_text_status: public series: Annual ACM Conference on Human Factors in Computing Systems volume: 33 place_of_pub: Seoul, Republic of Korea pagerange: 2943-2952 event_title: CHI'15, 33rd Annual ACM Conference on Human Factors in Computing Systems, Seoul, Republic of Korea, April 18 - 23, 2015 event_location: Seoul event_dates: 2015-04-20 - 2015-04-23 book_title: Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems editors_name: Begole, B editors_name: Kim, J editors_name: Woo, W editors_name: Inkpen, K citation: Tajadura Jimenez, A; Basia, M; Deroy, O; Fairhurst, M; Marquardt, N; Berthouze, N; (2015) As light as your footsteps: altering walking sounds to change perceived body weight, emotional state and gait.
