	Asterisk and Obelisk: Motion Codes for Passive Tagging Aakar Gupta, Jiushan Yang, Ravin Balakrishnan In Proceedings of UIST 2018 We propose Motion Codes, a passive tagging mechanism that is based on the kinesthetic motion of the user's hand. To scan a motion tag the user simply traces their finger over the pattern and the motion is decoded into the encoded information by an inertial motion ring. Paper Video
	HapticClench: Investigating Squeeze Sensations using Memory Alloys Aakar Gupta, Antony Albert Raj Irudayaraj, Ravin Balakrishnan In Proceedings of UIST 2017 Squeezing is one of the most intimate forms of human contact. HapticClench generates squeezing sensations on the wrist using shape memory springs. We show that HapticClench can generate up to 4 distinguishable loads, works well in distracted scenarios, has high spatial acuity and can communicate gradual progression information. Paper Video
	Summon and Select: Rapid Interaction with Interface Controls in Mid-air Aakar Gupta, Thomas Pietrzak, Cleon Yau, Nicolas Roussel, Ravin Balakrishnan In Proceedings of ISS 2017 Current freehand interactions rely on point & select wherein the constant hand movement in air for pointer navigation leads to hand fatigue quickly. We introduce summon & select, a new model for freehand interaction where, instead of navigating to the control, the user summons it into focus and then manipulates it. Paper Video
	Porous Interfaces for Small Screen Multitasking using Finger Identification Aakar Gupta, Muhammed Anwar, Ravin Balakrishnan In Proceedings of UIST 2016 The lack of a dedicated multitasking interface in smartphones results in frequent app switching which has obvious temporal, physical, and cognitive costs. Porous interfaces enable fast and efficient smartphone multitasking using translucent windows and finger identification. Paper Video
	Haptic Learning of Freehand Semaphoric Gestures Aakar Gupta, Antony Irudayaraj, Vimal Chandran, Goutham Palaniappan, Khai N. Truong, Ravin Balakrishnan In Proceedings of UIST 2016 Semaphoric gestures that act as shortcuts for mid-air commands require dedicated learning. We show that haptic gestural learning enables learning without visual engagement thus allowing users to learn in mobile scenarios. Paper
	DualKey: Miniature Screen Text Entry via Finger Identification Aakar Gupta, Ravin Balakrishnan In Proceedings of CHI 2016 (BEST PAPER NOMINATION) Fast and accurate access to letter keys for miniature screens remains an open question. We propose DualKey, a text entry technique that uses finger identification. In a 10-day study, DualKey outperforms existing techniques and achieves up to 25 words-per-min. Paper Video
	Direct Manipulation in Tactile Displays Aakar Gupta, Thomas Pietrzak, Nicolas Roussel, Ravin Balakrishnan In Proceedings of CHI 2016 (BEST PAPER NOMINATION) Wearables remain in persistent skin contact which demands the exploration of tactile interactions as rich as visual displays. We introduce the concept of a Direct Manipulation-enabled Tactile display that consists of a tactile pointing interface with a tactile screen, tactile pointer, and tactile targets. Paper Video
	mClerk: Enabling Mobile Crowdsourcing in Developing Regions Aakar Gupta, William Thies, Edward Cutrell, Ravin Balakrishnan In Proceedings of CHI 2012 mClerk enables crowdsourced distribution of local-language digitization tasks to low-end mobile phones by leveraging a little-known protocol to send small images via ordinary SMS. mClerk spread virally from 10 users to 239 users during a 5-week deployment in semi-urban India and digitized over 25,000 words. Paper MIT-TR
	Biometric Monitoring as a Persuasive Technology: Ensuring Patients Visit Health Centers in India's Slums Nupur Bhatnagar, Abhishek Sinha, Navkar Samdaria, Aakar Gupta, Shelly Batra, Manish Bhardwaj, William Thies In Proceedings of Persuasive 2012, Tuberculosis patients in rural India are required to visit a center over 40 times over 6 months. We explore the role of a biometric attendance terminal, which enrolled over 2,300 patients across 25 centers, in persuading patients to complete health visits in slum communities of New Delhi, India. Paper
	Collage: A Presentation Tool for the K-12 Classroom Saurabh Panjwani, Aakar Gupta, Navkar Samdaria, Edward Cutrell, Kentaro Toyama In Proceedings of ICTD 2010 Collage is a software presentation tool created exclusively for supporting instruction in a K-12 classroom in the developing world. The tool enables teachers to display digital scans of textbook pages along with digital multimedia in an interactive fashion. Paper Video
	Five years of IndiaHCI: A Scientometric Analysis Aakar Gupta In Proceedings of IndiaHCI 2015 After five consecutive years of IndiaHCI (2010-2014), we analyze the demographics, citations and themes of its proceedings to reflect upon the way forward for the conference and the HCI community in India.

DISHA: Multiple Mice in Narrative Content-based Computer Aided Learning for Children

Aakar Gupta, Praveen Shekhar, Navkar Samdaria, Mohit Jain, Joyojeet Pal
In Oral Presentation at IndiaHCI 2010

The MultiPoint technology enables multiple students, each with their own mouse, to simultaneously engage on a single PC. In collaboration with NCERT, India, we developed a unique design methodology that allows teachers to be the primary designers for collaborative learning games that supplement classroom teaching.
