However, performance on small and distant targets is impacted by the accuracy of the pointing device and the user's motor skills. Current pointing facilitation techniques are currently only applied in the context of the virtual hand, i.e. for targets within reach. We propose enhancements to Raycasting : filtering the ray, and adding a controllable cursor on the ray to select the nearest target. We describe a series of studies for the design of the visual feedforward, filtering technique, as well as a comparative study between different 3D pointing techniques. Our results show that highlighting the nearest target is one of the most efficient visual feedforward technique. We also show that filtering the ray reduces error rate in a drastic way. Finally we show the benefits of RayCursor compared to Raycasting and another technique from the literature.</jats:p><jats:p xml:lang="fr">Raycasting est la technique de pointage de cible la plus courante dans les environnements de réalité virtuelle. Cependant, sa performance sur des cibles à la fois petites et distantes est affectée par la précision du dispositif de pointage et les capa-cités motrices de l'utilisateur. Les techniques actuelles de facilitation du pointage ne sont actuellement appliquées que dans le contexte de la main virtuelle, c'est-à-dire pour les cibles à portée de main. Nous proposons des améliorations au Raycasting : le fil-trage du rayon, et l'ajout d'un curseur contrôlable sur celui-ci pour sélectionner la cible la plus proche. Nous décrivons une série d'études pour la conception d'aides visuelles, la technique de filtrage, ainsi qu'une étude comparative entre différentes techniques de pointage 3D. Nos résultats montrent que la mise en évidence de la cible la plus proche est l'une des techniques les plus efficaces de rétroaction visuelle. Nous montrons éga-lement que le filtrage du rayon réduit le taux d'erreur de manière drastique. Enfin, nous montrons les avantages de RayCursor par rapport à Raycasting et à une autre technique de la littérature.</jats:p></jats:abstract><publication_date media_type="online"><month>12</month><day>03</day><year>2019</year></publication_date><acceptance_date media_type="online"><month>12</month><day>03</day><year>2019</year></acceptance_date><publisher_item><item_number item_number_type="article_number">5933</item_number></publisher_item><program xmlns="http://www.crossref.org/AccessIndicators.xsd" name="AccessIndicators"><free_to_read start_date="2019-12-03"/><license_ref applies_to="am" start_date="2019-12-03">https://creativecommons.org/licenses/by/4.0</license_ref><license_ref applies_to="vor" start_date="2019-12-03">https://creativecommons.org/licenses/by/4.0</license_ref><license_ref applies_to="tdm" start_date="2019-12-03">https://creativecommons.org/licenses/by/4.0</license_ref></program><program xmlns="http://www.crossref.org/relations.xsd"><related_item><intra_work_relation identifier-type="uri" relationship-type="isSameAs">https://hal.science/hal-02158113v2</intra_work_relation></related_item></program><doi_data><doi>10.46298/jips.5933</doi><resource>http://jips.episciences.org/5933</resource><collection property="crawler-based"><item crawler="iParadigms"><resource>https://hal.science/hal-02158113v2/document</resource></item></collection><collection property="text-mining"><item><resource mime_type="application/pdf">https://hal.science/hal-02158113v2/document</resource></item></collection></doi_data></journal_article></journal></body></doi_batch>
